Postoperative changes in the full-field electroretinogram following sevoflurane anaesthesia.

BACKGROUND AND OBJECTIVE: We tested the hypothesis that disturbances of the visual pathway persist following general anaesthesia, even after normal clinical discharge criteria have been met. METHODS: We performed full-field flash electroretinography in the right eye of 10 unpremedicated ASA I patients who underwent N2O/sevoflurane anaesthesia. Electroretinograms were recorded preoperatively, immediately after discharge from the recovery room and 2 h after discontinuation of sevoflurane. The time at which postanaesthesia discharge score first exceeded 9 was also noted. Data were analysed using paired, one-tailed Student's t-test. RESULTS: Latency of the b-wave on the photopic electroretinogram was greater at each postoperative time point (30.5 +/- 0.9 and 30 +/- 1.3 ms), compared to preoperative values (29.2 +/- 0.8 ms, P < 0.001 and P = 0.04, respectively). The A-B amplitude of the b-wave was less postoperatively (220.3 +/- 52.7 and 210.3 +/- 42.7 pV) compared to values before operation (248.1 +/- 57.6 microV, P = 0.03 and P = 0.01, respectively). Oscillatory potential latencies were greater at each postoperative time point (21.4 +/- 0.5 and 20.8 +/- 0.6 ms) compared to before operation (20.4 +/- 0.4 ms, P < 0.001 and P = 0.03, respectively). Oscillatory potential amplitudes were less at the first postoperative time point (17.5 +/- 6.1 microV), compared to preoperative values (22 +/- 6.4 microV, P = 0.04). CONCLUSIONS: Postoperative electroretinogram abnormalities are consistently present in patients who have undergone N2O/sevoflurane anaesthesia. These abnormalities persist beyond the time at which standard clinical discharge criteria have been met.

Nitrous oxide does not increase vomiting in children after myringotomy.

The aim of this study was to establish whether nitrous oxide has a clinically important effect on postoperative vomiting in children after myringotomy. We studied 320 healthy children of ages 0.5-13 yr undergoing elective myringotomy and tube insertion. Induction and maintenance of anaesthesia were randomized to inhalation with either 70% N2O/30% O2/halothane or 100%O2/halothane. Surgical technique and postoperative management were not influenced by this study. Vomiting in the recovery room (PAR) and Day Care Surgical Unit (DCSU) was recorded by nurses unaware of the anaesthetic technique. Parents were contacted 24-48 hr after surgery to ascertain the incidence of vomiting after discharge. The groups were similar with respect to demographic data, except that the anaesthesia time was greater among the 158 patients in the N2O-treated group (11 +/- 4 vs 12 +/- 4 min, mean +/- SD). The incidence of vomiting was 13% in both groups. Most of the 42 patients that had emesis only vomited once or twice. The incidence of vomiting was not altered by sex (13% vs 13%) or duration of anaesthesia. The incidence of vomiting increased with increasing age. The children aged less than 3 yr vomited 4% of the time, those aged 3-5 vomited 11% of the time, those aged 6-8 yr vomited 17% of the time, while the incidence of vomiting among those aged 9-13 yr was 31%. Vomiting prolonged the postoperative hospital stay from 75 to 92 min, P < 0.001, ANOVA. In summary, we have been unable to demonstrate that N2O induces vomiting by children after a brief general anaesthetic for myringotomy.

Tramadol for postoperative shivering: a double-blind comparison with pethidine.

In most operating and recovery rooms, shivering is controlled by the use of humidifiers, warming blankets, and inhalation of humidified heated oxygen. However, pharmacological control is an effective alternate treatment modality. This randomized, double-blind trial, conducted in 30 ASA Grade 1 or 2 patients, was designed to explore the efficacy of tramadol and pethidine in the treatment of post-anaesthetic shivering. Tramadol is an inhibitor of the re-uptake of serotonin (5-hydroxytryptamine) and norepinephrine in the spinal cord. This facilitates 5-hydroxytryptamine release, which influences thermoregulatory control. We compared the efficacy of tramadol with that of pethidine, presently a widely used drug for the control of shivering. Patients received either tramadol 1 mg/kg or pethidine 0.5 mg/kg intravenously and the grade of shivering, pulse rate, blood pressure and respiratory rate were observed every 10 minutes after injection for one hour Shivering was significantly more likely to have ceased in the tramadol group (12 of 15 versus 4 of 15 cases, P<0.05) at 10 minutes after drug administration and this control was better sustained. No patients receiving tramadol had a recurrence of shivering. It is concluded that intravenous tramadol 1 mg/kg is more effective for the treatment of postoperative shivering than pethidine 0.5 mg/kg.

The Canadian four-centre study of anaesthetic outcomes: II. Can outcomes be used to assess the quality of anaesthesia care?

Since anaesthesia, unlike medical or surgical specialties, does not constitute treatment, this study sought to determine if methods used to assess medical or surgical outcomes (that is the determination of adverse outcome) are applicable to anaesthesia. Anaesthetists collected information on patient, surgical and anaesthetic factors while data on recovery room and postoperative events were evaluated by research nurses. Data on 27,184 inpatients were collected and the analysis of outcomes determined for the intraoperative, post-anaesthetic care unit and postoperative time periods. Logistic regression was used to control for differences in patient populations across the four hospitals. In addition, a random selection of 115 major events was classified by a panel of anaesthetists into anaesthesia, surgical and patient-disease contributions. Across the three time periods, large variations in minor outcomes were found across the four hospitals; these variations ranged from two- to five-fold after case-mix adjustment (age, physical status, sex, emergency versus elective and length of anaesthesia). The rates of major events and deaths were similar across three hospitals; one hospital had a lower mortality rate (P less than 0.001) but had a higher rate of all major events (P less than 0.0001). Of major events assessed by physician panels, 18.3% had some anaesthetic involvement and no deaths were attributable partially or wholly to anaesthesia. Possible reasons to account for these variations in outcome include compliance in recording events, inadequate case-mix adjustment, differences in interpretation of the variables (despite guidelines) and institutional differences in monitoring, charting and observation protocols. The authors conclude that measuring quality of care in anaesthesia by comparing major outcomes is unsatisfactory since the contribution of anaesthesia to perioperative outcomes is uncertain and that variations may be explained by institutional differences which are beyond the control of the anaesthetist. It is suggested that minor adverse events, particularly those of concern to the patient, should be the next focus for quality improvement in anaesthesia.

Ondansetron/promethazine combination or promethazine alone reduces nausea and vomiting after middle ear surgery.

STUDY OBJECTIVES: To determine the incidence of postoperative nausea and vomiting when a combination of ondansetron and promethazine is given prophylactically, and to ascertain the effect of postoperative nausea and vomiting on recovery room duration and patient satisfaction. DESIGN: Prospective, randomized, placebo-controlled, double-blind study. SETTING: University-affiliated tertiary-care hospital. PATIENTS: 87 ASA physical status I and II adult patients scheduled for middle ear surgery. INTERVENTIONS: Patients were randomly assigned to receive one of the following interventions intravenously: ondansetron 4 mg (Group 1), promethazine 25 mg (Group 2), ondansetron 2 mg plus promethazine 12.5 mg (Group 3, combination), or placebo (Group 4). MEASUREMENTS AND MAIN RESULTS: Independent, study blinded observers recorded complaints of nausea and number of episodes of vomiting for 24 hours following the patient's first response to commands. All patients were contacted the day after discharge to inquire about nausea and vomiting. The awakening time, postanesthesia care unit and day surgery unit durations, opioid use, and side effects were recorded. At the end of the 24-hour period, the study blinded observers asked patients for an overall assessment of their global anesthesia experience using an 11-point scale. During the 24-hour period, the incidence of postoperative nausea and vomiting was reduced from 74% (placebo) to 39% (promethazine; p = 0.03) and 29% (combination; p = 0.003). Compared with placebo, the severity of vomiting was significantly less in the combination group (p = 0.04). The number of very satisfied patients correlated negatively with the incidence of postoperative nausea and vomiting (p < 0.0001) and with the severity of vomiting (p = 0.003). CONCLUSION: The prophylactic use of an antiemetic with middle ear surgery may reduce postoperative nausea and vomiting over 24 hours, and the ondansetron/promethazine combination or promethazine alone are cost-effective choices. Finally, the combination reduced significantly the severity of vomiting.

[The washout behavior of isoflurane following balanced anesthesia and its effect on postoperative oxygen supply].

Few studies have described the pharmacokinetics and pharmacodynamics of isoflurane (I) during the postoperative recovery room stay. In this study the influence of balanced anesthesia with I on the postoperative course was investigated by studying pulmonary washout of I and its effect on arterial oxygen saturation. METHODS. Following institutional approval and informed consent, 50 patients (ASA I and II) scheduled for lateral fenestration for intervertebral disc herniation participated; all had no previous record of cardiopulmonary problems. Induction of anesthesia was achieved with intravenous alcuronium 0.03 mg/kg, fentanyl 0.003 mg/kg, thiopental 5 mg/kg, and succinylcholine 1.5 mg/kg followed by alcuronium 0.09 mg/kg before changing to the prone position. Anesthesia was maintained with controlled ventilation in a rebreathing system (fresh gas flow FGF) = 3.01/min, FIO2 = 0.3 in N2O, plus 0.8 Vol.-% cIet = 1.3 MAC). Near the end of surgery I was discontinued and IGI was increased to 61/min O2 for 10 min. Patients then returned to breathing ambient air. Extubation was carried out as soon as a minimum tidal volume of 400 ml was obtained. End tidal I concentration (cIet; Vol.-%) was measured by infrared absorption (Normac, Datex) and O2 saturation by pulse oximetry (Biox III, Ohmeda). Datum point of the pulmonary I-washout curve was the mean end-tidal I concentration obtained 15 min before terminating I (cIAW). Effects of duration of anesthesia, Broca index, and amount of I administered (tidal volume x inspiratory I concentration x min; ml) on I-washout were assessed. A pulse-oximetric O2 saturation of less than 90% was regarded as hypoxygenation. RESULTS. Mean duration of anesthesia for both males and females was 85 +/- 25 min, mean Broca index 102 +/- 13. The amount of I administered with the inspiratory volume was 5.661 +/- 2.194 1 I (1.0 +/- 0.4 Vol.-%). Mean I-regression (Fig. 3) was 236 x 10(-5) Vol.-%/min (Figs. 1 and 3). Mean I-washout 60 min after extubation was 44.6 +/- 15.2% of the administered amount. Adequate spontaneous breathing began a mean of 17 min after the end of I exposure, corresponding to 20% cIet of washout. All patients were extubated after a mean of 22 min at a mean etI of 17% of washout. After extubation, pulse oximetry indicated hypoxygenation in 18 patients (= 36%) during 2 periods (Fig. 4): (1) at a mean cIet of 0.1 Vol.-% (= 15% of washout) after a mean of 8 min; and (2) at a mean cIet of 0.08 Vol.-% (= 12% of washout) a mean of 19 min following extubation. Further episodes of hypoxygenation occurred as much as 40 min post-extubation. (ABSTRACT TRUNCATED AT 400 WORDS)

Transient blindness associated with transurethral resection of the prostate.

Visual impairment or even transient blindness can result from transurethral resection of the prostate when glycine is used as the irrigating fluid. Electroretinograms were obtained from patients in the anesthetic preparation area and in the recovery room immediately after surgery. Four patients reported visual aberrations ranging from a "gray darkening" to "light perception only" coincident with elevated serum levels of glycine. Electroretinograms consistently demonstrated a loss of oscillatory potentials only in those patients with visual impairment. Thirty-hertz "flicker-following" was also attenuated. The excessive serum levels of glycine may contribute to visual impairment and may account for the dropout of oscillatory potentials generated by the retina due to glycine's role in the retina as an inhibitory transmitter.

Effect of steroids on posttonsillectomy pain in adults.

OBJECTIVE: To determine whether a single intraoperative dose of intravenous dexamethasone has an effect on pain after tonsillectomy. DESIGN: Double-blinded randomized controlled clinical trial. SUBJECTS: Thirty-four consecutive nonpediatric patients presenting for tonsillectomy. INTERVENTION: Patients scheduled for electrocautery tonsillectomy were randomized to receive either intravenous dexamethasone or placebo during surgery. Pain was measured twice daily for 10 days by means of a visual analog scale. RESULTS: There were no statistically significant differences between the groups, but the dexamethasone group had a trend to report less pain over the first several days. The dexamethasone group received less analgesic in the recovery room, but there were no differences between the groups in the 10 days afterward. CONCLUSIONS: There is evidence that a single dose of dexamethasone reduces pain after tonsillectomy to a small degree. A single dose was not associated with adverse effects, so the risk-benefit ratio may be favorable for this practice.

Influence of minor ear surgery on infrared tympanic thermometry.

BACKGROUND: Infrared tympanic thermometry (ITT) is often used for postoperative recovery room monitoring regardless of recent minor otologic surgery. OBJECTIVE: To evaluate the use of ITT in pediatric patients who have undergone bilateral myringotomy with insertion of pressure-equalizing tubes. DESIGN: A prospective cohort study. SETTING: Tertiary care academic medical center. PATIENTS: Consecutive patients of a staff pediatric otolaryngologist (M.A.R.): (1) ear surgery group, children aged 10 years or younger undergoing bilateral myringotomy with insertion of pressure-equalizing tubes and (2) non-ear surgery group, children aged 10 years or younger undergoing bilateral tonsillectomy with or without adenoidectomy. INTERVENTIONS: Immediate preprocedure temperature measurements included right and left ear ITT. Immediate postprocedure temperature measurements included right and left ear ITT and thermistor probe rectal temperature. MAIN OUTCOME MEASURES: The average difference between the preprocedure and postprocedure tympanic temperature in the ear surgery group was compared with that in the non-ear surgery group. The average difference between postprocedure rectal and ear temperature in the ear surgery group was compared with that in the non-ear surgery group. RESULTS: There were 20 patients (40 ears) in the ear surgery group and 20 patients (40 ears) in the non-ear surgery group. In the ear surgery group, the average difference between the preprocedure and postprocedure tympanic temperature (0.55 degrees C) was not significantly different from that (0.62 degrees C) in the non-ear surgery group (P =.66, 1-way analysis of variance). In the ear surgery group, the average difference between postprocedural rectal and ear temperature (1.94 degrees C) was not significantly different from that (1.89 degrees C) in the non-ear surgery group (P =.76, 1-way analysis of variance). CONCLUSION: Recent minor ear surgery (bilateral myringotomy with insertion of pressure-equalizing tubes) does not have a significant effect on ITT measurements in pediatric patients.

Traditional tonsillectomy compared with bipolar radiofrequency thermal ablation tonsillectomy in adults: a pilot study.

OBJECTIVES: To assess the morbidity and efficacy of bipolar radiofrequency thermal ablation tonsillectomy and compare it with traditional cold dissection tonsillectomy with diathermy hemostasis. DESIGN: Prospective, randomized, single-blinded, controlled clinical study. SETTING: Helsinki University Central Hospital, Department of Otorhinolaryngology-Head & Neck Surgery, Helsinki, Finland. PATIENTS: Forty healthy volunteer patients aged 18 to 65 years admitted for elective tonsillectomy with recurrent or chronic tonsillitis, obstructive tonsillar hypertrophy, or history of quinsy. Two patients were excluded from the study and 1 patient cancelled the operation. INTERVENTIONS: Nineteen patients underwent a traditional cold dissection tonsillectomy with diathermy hemostasis, and 18 patients underwent a bipolar radiofrequency thermal ablation tonsillectomy. There was no intergroup difference in age, sex, weight, and indications for tonsillectomy. The subjects were not informed of the type of procedure until the telephone interview 3 weeks after the operation. MAIN OUTCOME MEASURES: Operating time and intraoperative blood loss; need for anesthetics during the operation; different recovery indicators in the recovery room (ie, duration and medications administered), surgical ward (ie, medications administered, use of corticosteroids, general condition, and status of the uvula on the first postoperative day), and in the 2 weeks following surgery (ie, visual analog scale scores on 6 symptoms, medications needed, the day patients returned to work, use of antibiotics, and retreatment acceptance); and complications and certain laboratory parameters. RESULTS: There was a statistically significant but clinically insignificant difference in operating time and intraoperative blood loss in favor of the traditional tonsillectomy group. The other outcome measures showed no statistically significant differences. CONCLUSION: Bipolar radiofrequency thermal ablation and traditional tonsillectomy were associated with similar postoperative morbidity.

Temperature-controlled radiofrequency tonsil reduction in children.

OBJECTIVE: To evaluate the safety and efficacy of temperature-controlled radiofrequency tonsil reduction in the treatment of children with a sleep-related breathing disorder associated with tonsillar obstructive hypertrophy. DESIGN: Prospective, nonrandomized, case series feasibility study of children meeting the criteria for tonsillectomy or adenotonsillectomy for the treatment of an obstructive sleep-related breathing disorder. SETTING: Community-based hospital. Patients Ten children, aged 4 to 13 years, presenting consecutively to a community-based otolaryngology practice with tonsillar or adenotonsillar obstructive hypertrophy implicated clinically in causing a sleep-related breathing disorder; their parents consenting to temperature-controlled radiofrequency tonsil reduction instead of surgical tonsillectomy. Intervention Temperature-controlled radiofrequency tonsil reduction, along with surgical adenoidectomy, if adenoids were present, under general anesthesia. MAIN OUTCOME MEASURES: Tonsil size reduction, treatment morbidity, and symptom improvement with follow-up to 1 year. Baseline and 3-month posttreatment polysomnographic data were used. RESULTS: There was a reduction in tonsil size at 1 year of 75.0% on average, without evidence of regrowth during the 1-year follow-up. All children were drinking liquids in the recovery room, and most were eating soft diets within 6 hours; 8 of the 10 children were eating a normal diet by day 5. On average, the return to normal activity was 3.9 days, with 2.9 days of parental loss of work time. Quality-of-life variables all improved. Snore indexes decreased by 88.6%. Polysomnography at 3 months revealed an 84.2% reduction in the apnea index and a 52.3% reduction in the apnea/hypopnea index. There were no complications. CONCLUSION: Temperature-controlled radiofrequency tonsil reduction seems to be a safe, effective, and minimally morbid treatment for tonsil hypertrophy in children with obstructive sleep-related breathing disorders.

Effect of perioperative administration of ropivacaine with epinephrine on postoperative pediatric adenotonsillectomy recovery.

OBJECTIVES: To determine whether perioperative administration of ropivacaine hydrochloride with epinephrine decreases postoperative pain following adenotonsillectomy and to determine the pharmacokinetics of ropivacaine following injection. DESIGN: Prospective, randomized, double-blind clinical trial. SETTING: University pediatric ambulatory center. PARTICIPANTS: A total of 130 children, aged 2 to 12 years, undergoing adenotonsillectomy. INTERVENTION: Patients received injections, in the tonsillar fossae, of isotonic sodium chloride solution or 0.5% ropivacaine hydrochloride with epinephrine immediately following tonsillectomy. MAIN OUTCOME MEASURES: Modified objective pain score, time to 100 mL of oral intake, serial plasma ropivacaine levels, use of analgesics, incidence of retching and emesis, and other symptoms. RESULTS: Fifty-three patients (80%) in the ropivacaine group had detectable plasma levels in at least 3 of the 4 measurement time periods. The mean +/- SD peak concentration (C(max)) was 0.71 +/- 0.33 micro g/mL and the half-life was 0.96 hours. The average modified objective pain scores over all time points favored the placebo group (P =.06 test of between-subjects effects). Similarly, the average behavior score over time favored the placebo group (P =.046 test of between-subjects effects). Neck pain was better in the placebo group when averaged over postoperative days 1, 3, 7, and 14 (P =.04). The percentage of patients who had retching in the recovery room was greater in the ropivacaine group (41% vs 19%, P =.006). CONCLUSIONS: The injection of 0.5% ropivacaine with epinephrine immediately following adenotonsillectomy results in a measurable plasma level. Ropivacaine with epinephrine injection does not reduce pain postoperatively and adversely affects behavior scores, neck pain scores, and retching frequency compared with placebo. Ropivacaine with epinephrine injection for postoperative analgesia is not recommended for this patient population.

Radiofrequency ablation of microcystic lymphatic malformation in the oral cavity.

OBJECTIVE: To determine the efficacy and safety of radiofrequency (RF) ablation of vesicles and the resulting symptomatic control of microcystic lymphatic malformation (LM) in the oral cavity. DESIGN: An institutional review board-approved retrospective study with follow-up telephone interview. SETTING: Tertiary pediatric medical center. Patients Eleven children (6 girls and 5 boys), aged 4 to 16 years, presenting between August 1, 2002, and December 1, 2004. Intervention Radiofrequency ablation of LM in the oral cavity. MAIN OUTCOME MEASURES: Symptoms related to LM, postoperative oral intake, and postoperative antibiotic requirements. RESULTS: Eleven patients presented with microcystic LM involving the lips, tongue, floor of the mouth, or buccal mucosa. Complaints included bleeding, infection, swelling, vesicle formation, and malocclusion. Patients underwent RF ablation (coblation) of oral cavity lesions. Seven (64%) of the 11 patients were able to tolerate oral intake in the recovery room. The need for antibiotics was reduced after RF ablation. All patients related diminished bleeding, pain, infection, or vesicle formation, with more than half reporting a significant improvement (6 patients) or complete resolution (1 patient). Five (62%) of 8 parents stated that the improvement after RF ablation was superior to that following previous procedures. CONCLUSIONS: Subtotal RF ablation of LM appears to be safe, with early postoperative oral intake and minimal postoperative pain. Further studies are needed to determine long-term control of LM.

Extraordinary growth of giant cell reparative granuloma during pregnancy.

A 25-year-old woman had a giant cell reparative granuloma (GCRG) in the nasal fossa during the fifth month of pregnancy. This was treated with a partial excision, but the lesion recurred three months later. By this time, there was extension into the anterior fossa. Because of rapidly decreasing visual acuity, headache, and facial pain, a combined craniofacial approach was undertaken. The lesion encroached on the optic chiasm and a piecemeal, but incomplete, removal of the lesion was performed. The patient spontaneously gave birth to a normal child while in the recovery room. She received no additional therapy and her symptoms disappeared. She remains well 11 years later. The course of disease in this patient is compared with eight other patients from the literature who had GCRG during pregnancy.

Alternatives to packing in septorhinoplasty.

Nasal packing is considered routine by most physicians and patients at the completion of nasal and septal surgery. Yet the rationale for this maneuver is not clearly defined by reported investigation or logical analysis. We discuss 75 consecutive nasal surgical procedures completed without packing. There were two postoperative episodes of bleeding, both from pyriform aperture incisions for lateral osteotomy and both managed in the recovery room with an absorbable gelatin sponge. Technical refinements such as scrupulous preoperative history taking, through-and-through suturing of the entire septal flaps, small-caliber osteotomy, meticulous closure of all intranasal incisions, and proper application of a conforming dressing are essential for hemostasis. We offer specific procedural guidance to minimize the risk of postoperative nasal bleeding.

Short-stay outpatient tonsillectomy.

OBJECTIVE: To determine the risk of complications after discharge in outpatient adenotonsillectomy after a short (< 6 hours) period of postoperative observation. DESIGN: Retrospective chart review. SETTING: Outpatient surgery center at a university hospital. PATIENTS: All patients 18 years of age or less who were scheduled for adenotonsillectomy or tonsillectomy from January 1988 through December 1991. Two hundred fifty-five patient records were reviewed. Twenty-two patients were excluded from the study because of various complicating medical conditions that required planned overnight hospitalization leaving a study population of 233 patients. MAIN OUTCOME MEASURES: (1) Rate and type of complications; (2) duration of postoperative observation. RESULTS: Complication rates of bleeding, emesis, dehydration, and readmission were compared with rates deemed acceptable in the literature (< or = 10%). Power analysis demonstrated that the patient number was sufficient to establish a 95% confidence interval for a complication rate of 0% to 10%. The mean duration of postoperative observation was 136 +/- 48 minutes. Complications included bleeding, emesis, dehydration, and nonscheduled admissions. The total complication rate was 9% (95% confidence interval, 5.5% to 12.7%). The rate of primary bleeding was 1.4%, and all primary bleeding occurred within 75 minutes of arrival in the recovery room; no primary bleeding occurred after discharge from day surgery. This complication rate is comparable with rates previously described in the literature for patients who were observed for a 6- to 12-hour period. CONCLUSION: The findings in this study suggest that short periods of observation are safe for outpatient pediatric patients undergoing adenotonsillectomy after discharge criteria are met.

The Millikan modified mesh-plug hernioplasty.

HYPOTHESIS: A modified technique for mesh-plug hernioplasty is a safe and efficacious option for primary unilateral inguinal herniorrhaphy. DESIGN: Prospective analysis of 1056 patients who underwent primary unilateral inguinal hernioplasty. SETTING: A private university medical center. PATIENTS: One thousand twenty-five men and 31 women (mean age, 49 years) with primary unilateral inguinal hernias that were surgically repaired between May 1, 1997, and November 1, 2001. INTERVENTION: We performed a modified technique using a mesh plug and local anesthesia with intravenous sedation. The modified technique consisted of placing the mesh plug into the preperitoneal space and suture fixation of the plug using the inner petals. MAIN OUTCOME MEASURES: Surgical morbidity, hernia recurrence, postoperative pain medication used, and return to normal activities. RESULTS: We included 642 indirect and 414 direct hernias. Mean operative time was 25 minutes; mean recovery room time, 45 minutes. All procedures were performed as outpatient surgery. One thousand thirteen patients (95.9%) returned to normal activities within 3 days. All manual laborers returned to work on postoperative day 14. Only 169 patients (16.0%) required prescription pain medication. At 1-year follow-up, 1045 patients (99.0%) have been examined, and 1 recurrence (0.1%) has been detected. No mesh infection has occurred, and 19 hematomas spontaneously resolved. Five patients (0.5%) required treatment for persistent postoperative pain. CONCLUSIONS: The modified mesh-plug hernioplasty uses a minimum of medical resources and is associated with a small amount of postoperative pain and an early return to normal activities and manual labor with a minimal documented early recurrence rate. The Millikan modified mesh-plug hernioplasty should be adopted as the gold standard for unilateral primary inguinal hernioplasty.

Double-blind, prospective, randomized study of warmed, humidified carbon dioxide insufflation vs standard carbon dioxide for patients undergoing laparoscopic cholecystectomy.

HYPOTHESIS: Patients undergoing warmed, humidified carbon dioxide (CO2) insufflation for laparoscopic cholecystectomy will (1) maintain a warmer intraoperative core temperature, (2) have their surgeon experience less fogging of the camera lens, and (3) have less postoperative pain than patients undergoing laparoscopic cholecystectomy with standard CO2 insufflation. DESIGN: A double-blind, prospective, randomized study comparing patients undergoing laparoscopic cholecystectomy with standard CO2 insufflation vs those receiving warmed, humidified CO2 (Insuflow Filter Heater Hydrator; Lexion Medical, St Paul, Minn) was performed. Main variables included patient core temperature, postoperative pain, analgesic requirements, and camera lens fogging. RESULTS: One hundred one blinded patients (69 women, 32 men) undergoing laparoscopic cholecystectomy were randomized into 2 groups-52 receiving standard CO2 insufflation (group A) and 49 receiving warmed, humidified CO2 (group B). Mean patient intraoperative core temperature change (group A decreased by 0.03 degrees C, group B increased by 0.29 degrees C, P =.01) and mean abdominal pain (Likert scale, 0-10) at 14 days postoperatively (group A, 1.0; group B, 0.3; P =.02) were different. Other variables (camera lens fogging, early postoperative pain, narcotic requirements, recovery room stay, and return to normal activities) between groups were similar. CONCLUSION: While patients undergoing laparoscopic cholecystectomy with warmed, humidified CO2 had several advantages that were statistically significant, no major clinically relevant differences between groups A and B were evident.
