Continuous thoracic epidural infusions for postoperative analgesia after pectus deformity repair.

PURPOSE: To determine whether continuous epidural analgesia after repair of a pectus deformity is a viable and safe alternative to high-dose narcotics in children. METHODS: Data were collected prospectively for 19 children (4 to 17 years of age; 15 boys, 4 girls) who underwent pectus excavatum (14) or carinatum (5) repair between June 1, 1991 and July 1, 1994. Seventeen had a thoracic epidural catheter placed for postoperative pain control and two did not. The epidural catheter was routinely plead preoperatively by the anesthesiologist at the T3-T8 level, after induction of general anesthesia. Epidural catheters were test-dosed with local anesthesia alone or in combination with fentanyl, and afterward a continuous epidural infusion was maintained on the floor. Postoperative pain was assessed by nursing and house staff on the Wong-Baker scale, with adjustment of the dose rate or analgesic medication as appropriate. RESULTS: All patients had extubation before leaving the operating room and were sent to the general pediatrics ward after leaving the recovery room. The average duration of the epidural was 69 hours (range, 20 to 116 hours). Sixteen patients received their test epidural dose preoperatively, and one patient had his in the recovery room. Fifteen epidural initially were dosed with bupivicaine (1 to 2 mg/kg) alone or in combination with fentanyl (1 to 2 micrograms/kg). Two patients received initial doses of lidocaine (1 to 1.5 micrograms/kg). Ten of 17 patients received fentanyl (1 microgram/kg/h) with bupivicaine (0.5 to 1.0 mg/kg/h) in the epidural as their maintenance medication, and the remainder received bupivicaine alone at the same dosage rate. Eight of 17 patients required additional intermittent supplemental narcotics, with an average of two doses of intravenous morphine per day (0.1 mg/kg) over the first 3 postoperative days. In contrast, the two patients who did not have an epidural catheter for pain control required high-dose intravenous morphine (0.2 mg/kg) every 2 to 3 hours for the first 3 to 4 postoperative days. No catheter-related complications occurred. CONCLUSION: Thoracic epidural analgesia was completely successful in nine (53%) children who underwent repair of pectus deformity, and effectively reduced the intravenous narcotic demand in the other eight. Pain control was excellent, and no catheter-related complications were encountered. The data show that this method of analgesia in children is a safe and attractive alternative to intravenous narcotics, and eliminates the potential disadvantages of sedation and respiratory compromise.

Perioperative gastric aspiration increases postoperative nausea and vomiting in outpatients.

The efficacy of aspiration of gastric contents to reduce postoperative nausea and vomiting was investigated in a controlled randomized, double-blind study of 265 outpatients. Patients in the treated group had their stomachs aspirated with an orogastric tube. In the control group no tube was inserted. Data on the incidence of nausea and vomiting were collected in the recovery room, the day surgery unit and the day after surgery. The overall incidence of postoperative nausea and vomiting was comparable in the two groups. It was also comparable in the recovery room and the day surgery unit. However, treated patients had a higher incidence of both nausea (26.5% vs 12.0%, P < 0.005) and vomiting (16.7% vs 6.8%, P < 0.02) after their discharge from the day surgery unit. We conclude that aspiration of gastric contents with an orogastric tube does not decrease postoperative nausea and vomiting in outpatients and may increase it after discharge of the patient.

[Patient-controlled analgesia using meperidine in the postoperative period after cholecystectomy. Study of possible complications at 2 different levels of surveillance].

OBJECTIVES: To ascertain the side effects of intravenous meperidine in patient-controlled analgesia under two levels of surveillance: one in the recovery room and one in the hospital's surgical ward. PATIENTS AND METHODS: Patient-controlled analgesia with meperidine was made available to 80 patients who had undergone cholecystectomy by laparotomy. Instances of nausea/vomiting, pruritus, urinary retention and technical problems were recorded, as well as arterial gas levels (cooximetry) on the first, third, twelfth and twenty-fourth hours after surgery. We also recorded meperidine consumption and its relationship to side affects. RESULTS: Side effects were associated with higher consumption of meperidine (437.0 +/- 117.7 mg vs 297.7 +/- 135.9 mg in those experiencing no side effects), with more episodes of PO2 < 70 mmHg and SO2 < 90% on the ward than in the recovery room (24 and 10 as compared to 85 and 30, respectively). Patients presenting adverse side effects were significantly older (76.6 +/- 13.5 vs 58.1 +/- 11.1 years). CONCLUSIONS: Given that age and higher meperidine consumption were associated with more frequent occurrence of hypoxic episodes, patients should receive greater surveillance on the ward, with oxygen therapy, monitoring of accumulated consumption and caution used with older patients.

Simple narcotic kits for controlled-substance dispensing and accountability.

Operating rooms require a storage, dispensing and accounting system for restricted drugs which satisfies narcotics control authorities and is compatible with efficient care of patients. We describe narcotic kits containing fentanyl-morphine-midazolam, alfentanil-midazolam and sufentanil-midazolam, for general operating rooms, and two kits with larger quantities of fentanyl and sufentanil for cardiac operating rooms. The container for each kit is a video cassette holder which has a foam-rubber liner with sculpted depressions for each ampoule. Sealed kits are delivered each morning from pharmacy to the locked narcotics cupboard in the recovery room. On request, the recovery room nurse unlocks the cupboard and the anaesthetist signs out the required kit(s) for the day. A drug utilization form is enclosed with each kit, on which the anaesthetist records the amount of drug administered to each patient, and before returning the kit to the locked narcotics cupboard, the total amount of each drug used, discarded, and returned. Used kits are collected the following morning by a pharmacy technician who reconciles the contents and drug form of each kit. More than 40 staff anaesthetists and a similar number of residents have used the system for seven years, during which time 130,000 patients have passed through the operating rooms. Detection of one case of drug diversion by a staff anaesthetist was made partly by the control system, but mainly by behavioural changes. The system is simple, inexpensive, and effective and has been well received by the departments of pharmacy, anaesthesia, and nursing.

The effect of nitrous oxide and carbon dioxide pneumoperitoneum on operative and postoperative pain during laparoscopic sterilization under local anesthesia.

STUDY OBJECTIVE: To compare carbon dioxide and nitrous oxide pneumoperitoneum with respect to intraoperative and postoperative pain during laparoscopic sterilization under local anesthesia. DESIGN: Randomized, double-blind study of pain during surgery and at 15 minutes, 1 hour, and 24 hours postoperatively. SETTING: Regional Medical Center, Memphis, Tennessee. PATIENTS: Women scheduled for laparoscopic sterilization under local anesthesia. Interventions. Forty-nine patients were randomized to carbon dioxide and 56 to nitrous oxide pneumoperitoneum. MEASUREMENTS AND MAIN RESULTS: Pain was assessed using a modified McGill pain questionnaire. Intraoperative pain was measured by the amount of supplemental narcotic required. Analgesic use in the recovery room and during the first 24 hours postoperatively was compared. Demographics for both groups were similar. The groups had no statistical differences in pain during surgery or at any of the postoperative time periods. Recovery room analgesia requirement was similar, but the nitrous oxide group used fewer pain tables (0.98 vs 0.42 tablets) in the first 24 hours. CONCLUSIONS: There is no difference in intraoperative and postoperative pain between nitrous oxide and carbon dioxide pneumoperitoneum for laparoscopic sterilization when used in conjunction with a protocol such as ours.

Recovery after general anaesthesia for laparoscopy.

Recovery after two methods of light general anaesthesia for gynaecological laparoscopy was studied. For this purpose, 30 patients were divided into two equal groups (A and B). The patients in group A were anaesthetized with thiopentone, fentanyl and suxamethonium infusion, while the patients in group B received inhalation anaesthesia with enflurane and suxamethonium infusion. Both groups were normoventilated with nitrous-oxide and oxygen mixture. A battery of recovery tests was applied in the recovery room. The patients who received inhalation anaesthesia with enflurane scored better in the recovery tests, and reached preoperative values after 3 h in the recovery room. Inhalation anaesthesia with enflurane was accepted well by the patients and provided good working conditions for the surgeons. It is suitable for outpatient gynaecological laparoscopy because it ensures rapid recovery.

The effectiveness of labetalol in treating postoperative hypertension.

During the postanesthesia recovery period, surgical patients often exhibit an increased arterial blood pressure. Although these transient increases in blood pressure are usually benign, significant morbidity and mortality may result from complications of postoperative hypertension. The purpose of this study was twofold: to determine the frequency of postoperative hypertension in one particular recovery room, and to determine the efficacy of labetalol as an antihypertensive drug in this setting. This study included both a retrospective and prospective component. The retrospective portion involved review of 465 records of patients admitted to the recovery room at a large, private eastern medical college. Nearly 20% of patients admitted were found to have blood pressures in the range of our study's criteria for hypertension. Records were also reviewed for types of therapeutic interventions used to treat hypertension and determinations of their success or failure. The prospective portion of the study evaluated treatment protocols for postoperative hypertension with graduated intravenous injections of labetalol in 30 patients. Blood pressure was effectively controlled with an average of 25 minutes for all patients and remained effective for 24 hours postoperatively.

Interactive microcomputer for acquisition of patient information.

Written records and first-generation hospital information systems do not meet their primary purpose to assist physicians in solving patients' problems. Simply automating the present chart formats is not the answer. An example of the concept needed for charting is the intensive care unit chart. Anesthesiology charts provide little useful information for the continued care of the patient postoperatively. They serve principally as legal archival documents. Automation of the anesthesia record should free the anesthesiologist of the need to search for preoperative information and to manually record most information intraoperatively. Decisions about how much data to archive and how to extract the data pertinent to continuing care are the challenges for physicians. The technologic tools are available for the design and implementation of a software system that focuses on effective communication of the patient's problems throughout the perioperative period as the patient moves from ward to operating room, through the recovery room and intensive care unit, and to the ward and home.

General anaesthetic management for laser resection of central airway lesions in 85 procedures.

The perioperative course of 41 patients undergoing 85 endoscopic laser resections of central airway lesions under general anaesthesia was reviewed. The CO2 laser was used in 60 procedures and the Nd:YAG in 25. Intravenous anaesthesia and Venturi ventilation were utilized for 65 resections; 20 procedures involved predominantly inhalation anaesthesia via the ventilating bronchoscope. Significant intraoperative complications included arterial desaturation (SaO2 less than 90 per cent) in 26 per cent of procedures, and refractory hypertension requiring vasodilator therapy in 19 per cent. Intravenous anaesthesia was associated with a longer duration of recovery room care and a higher incidence of postoperative respiratory complications (delayed extubation, recovery room re-intubation and ventilation, and post-extubation stridor). Inhalation anaesthesia appeared to simplify the intraoperative management and decrease the incidence, duration and severity of immediate postoperative respiratory complications.

Cost comparison of radical retropubic and radical perineal prostatectomy: single institution experience.

OBJECTIVES: To perform a detailed comparison of the in-house hospital costs of patients undergoing radical perineal prostatectomy (RPP) and radical retropubic prostatectomy (RRP) performed with or without bilateral staging lymph node dissection (BPLND) for localized prostate cancer. METHODS: A retrospective cost review was done of a cohort of 402 consecutive radical prostatectomies performed at our institution during a 21-month period. The procedure was performed as RPP in 279 (69.4%) and RRP in 123 (30.6%) patients, of whom 10.4% and 61.8%, respectively, underwent BPLND under the same anesthesia. The hospital costs were evaluated for each patient using the categories of surgical, nursing, laboratory/transfusion, and pharmacy. Surgical costs were further subdivided into operating room, anesthesia, and recovery room costs. Univariate and multivariate statistical analyses were applied to identify predictors of procedure-related costs. RESULTS: The median hospital costs of patients undergoing RPP (7195 dollars, range 5052 dollars to 36,237 dollars) were substantially lower than those of patients undergoing RRP (9757 dollars, range 6935 dollars to 27,771 dollars; P = 0.001). The median costs for patients undergoing radical prostatectomy without BPLND were significantly lower in the RPP (7100 dollars, range 5052 dollars to 28,604 dollars) versus RRP (9169 dollars, range 6935 dollars to 16,705 dollars) patients (P = 0.001). The costs for RPP with BPLND (10,048 dollars, range 7529 dollars to 36,237 dollars) versus RRP with BPLND (9973 dollars, range 7658 dollars to 27,771 dollars) were not significantly different (P = 0.900). Patient age and nerve-preservation status did not significantly influence the procedure-related hospital costs. CONCLUSIONS: RPP may result in lower in-house costs per patient than RRP in those patients who do not require BPLND. Total hospital costs depend largely on the factors of operating room time, length of stay, and laboratory and transfusion requirements, which may vary among institutions.

Opportunities for control of hospital costs for total joint arthroplasty after initial cost containment.

Financial analysis of 391 joint replacement operations performed during 1996 determined that almost 80% of the hospital cost for joint replacement procedures was generated in the operating room, nursing units, recovery room, and pharmacy during the first 48 hours of hospitalization. Attempts to control or reduce the hospital cost of joint replacement operations should focus on these specific areas of opportunity.

Renin-aldosterone system and atrial natriuretic peptide during anesthesia in orthopedic patients over 80 years of age.

STUDY OBJECTIVES: To investigate the changes in plasma atrial natriuretic peptide, renin activity, and aldosterone during isoflurane anesthesia in patients over 80 years. DESIGN: Prospective, randomized, controlled study. SETTING: Operating rooms and postanesthesia recovery room of Hirosaki University Hospital and Hakodate Watanabe Hospital. PATIENTS: 36 patients undergoing reduction of femur neck fracture (18 patients ranging in age from 80 to 99 years and 18 patients ranging in age from 40 to 59 years as control). INTERVENTION: In all patients, anesthesia was induced with intravenous (i.v.) thiopental sodium 3 to 5 mg/kg succinylcholine 0.5 to 1.0 mg/kg for facilitating tracheal intubation and was maintained with 1.2% to 2.0% isoflurane in 50% oxygen. MEASUREMENTS AND MAIN RESULTS: Plasma atrial natriuretic peptide (ANP), plasma renin activity (PRA), and plasma aldosterone (PA) levels were assayed. Blood samples were obtained on the following occasions: before the induction of anesthesia, 15 minutes after skin incision, 90 minutes after anesthesia induction, and the 60 minutes after the end of surgery. Plasma renin activity and PA levels in patients from 40 to 59 years increased significantly 90 minutes after induction, whereas PRA and PA levels in patients over 80 years were unchanged. There were significant differences in PRA and PA levels between both groups at any time of measurements. Plasma ANP levels of patients over 80 years were significantly elevated at 90 minutes induction. Plasma ANP levels in patients over 80 years at 90 minutes after the induction and 60 minutes after the end of surgery were significantly higher than those of patients from 40 to 59 years. Plasma renin activity in hypertensive patients over 80 years at 90 minutes after the induction was significantly lower than that observed in normotensive patients. The renal loss of sodium was increased in the hypertensive patients. CONCLUSIONS: Orthopedic patients over 80 years of age have decreased PRA and PA, increased ANP, and renal loss of sodium as compared with patients 40 to 59 years, during isoflurane anesthesia. Plasma renin activity at 90 minutes after induction was decreased in hypertensive patients over 80 years, but PA and ANP were not affected by hypertension during anesthesia.

Effect of ilioinguinal nerve block on the catecholamine plasma levels in orchidopexy: comparison with caudal epidural block.

BACKGROUND: Both caudal epidural and ilioinguinal/iliohypogastric nerve blocks have been used to provide effective intra- and postoperative analgesia. Stress response hormone levels can be used as an objective method to assess the analgesic efficacy of the anaesthetic techniques used in infraumbilical surgery in children. In this study, we compared catecholamine blood levels in children undergoing these two different supplementary analgesic/anaesthetic techniques. METHODS: Thirty male paediatric patients undergoing orchidopexy, ASA I, received inhalation general anaesthesia, and were randomly allocated to one of two groups: a caudal group (n = 15) and an ilioinguinal/iliohypogastric nerve block group (n = 15). Plasma epinephrine and norepinephrine concentrations were measured at the induction time, at the end of surgery, and in the postanaesthesia care unit. Postoperative pain score was also assessed in the postanaesthesia care unit. RESULTS: In both groups, there was a substantial decrease in the catecholamine blood levels; however, there were significantly higher levels of epinephrine in the ilioinguinal group at the end of surgery (P = 0.008) and in the recovery room (P = 0.02) and a significant higher level of norpinephrine in the recovery room (P = 0.008). CONCLUSIONS: The result of this study revealed that caudal epidural block was more effective than ilioinguinal block in suppressing the stress response as reflected in epinephrine and norepinephrine blood levels in orchidopexy patients.

The critically ill patient after hepatobiliary surgery.

BACKGROUND: We analyzed the causes and results of utilization of critical care services in the special care unit in patients after surgical procedures performed by the hepatobiliary surgical service during a 23-month period. RESULTS: Thirty-two of 537 patients (6.0%) required postoperative admission to the special care unit. Twenty-one patients were admitted directly from operating room or from recovery room because of inability to wean from ventilator (n = 10), hypovolemic shock (n = 4), myocardial ischemia or infarction (n = 2), sepsis (n = 2), upper gastrointestinal bleeding (n = 2), and acute renal failure (n =1). Eleven postoperative patients were admitted from floor care for respiratory failure (n = 4), cardiac dysrhythmia or infarction (n = 4), sepsis (n = 2), and upper gastrointestinal bleeding (n = 1). Thirty-eight per cent of patients (n = 12) admitted to the special care unit after surgery died. By multivariate analysis, total postoperative stay in the special care unit that was greater than median total duration of stay of 4.5 days was the only independent predictor of mortality (P = 0.041). CONCLUSIONS: Respiratory failure was the predominant component of all complications after hepatobiliary surgery. No clinically useful predictors of eventual outcome could be identified.

Practice Patterns of Electroconvulsive Therapy: A California Perspective (1984).

The sixty-five California hospitals administering electroconvulsive therapy (ECT) during 1984 were surveyed regarding ECT practices to develop data on the community standard of care. Usable data were obtained from 58 hospitals. In each facility two psychiatrists usually administered ECT, including one psychiatrist who received credentials in or after 1977. Thirty-four brief-pulse and 43 sine-wave machines were in use. Treatment was performed on the psychiatric unit in 41.4% of the hospitals, in the operating room or the recovery room in 50% of the hospitals, and in other locations in 8.6% of the hospitals. The psychiatrist administered the anesthesia in 12 (21%) of the hospitals. Unilateral electrode placement was used in 42% of patients. The use of anesthetic agents, ancillary equipment, and staffing patterns is reviewed.

[Hypoxaemia during transportation of patients after anesthesia and upper abdomen surgery].

The incidence of hypoxaemia was studied in 100 patients breathing room air during their transportation from the operating room to the recovery room. Hypoxaemia (SaO2 less than 90%) occurred in 24 (24%) patients. Oxygen saturation rose quickly above 95% when oxygen was administered. The causes of hypoxaemia are discussed. Quick transportation and oxygen supply were recommended.

[Postoperative mental confusion in the elderly with hip fracture. Perioperative risk factors].

OBJECTIVE: To determine the incidence of postoperative mental confusion and perioperative risk factors in elderly patients with femoral neck fractures. PATIENTS AND METHODS: A prospective study of patients 65 years of age or older undergoing surgery for hip fracture with intradural anesthesia between March 1992 and August 1993. Although the total number of cases came to 162, only 50 patients were enrolled in the study: the rest were excluded mainly because of mental deficits presenting before surgery. Folstein's Mini-Mental State test was used to assess mental function. Risk factors analyzed were classified as preoperative, intraoperative (in the operating room and the recovery room) or postoperative (hospital ward). RESULTS: Eleven (22%) patients showed signs of postoperative mental confusion. Simple analysis revealed a correlation between mental confusion and ASA (p = 0.01), neuropsychiatric history (p = 0.03) and preoperative hemoglobulin, red blood cell and urea nitrogen levels (p = 0.02). Multifactorial discriminant analysis indicated that patients with low red cell counts before surgery, high urea nitrogen and neuropsychiatric histories were more predisposed (p = 0.004) to mental confusion. CONCLUSIONS: A high incidence of postoperative mental confusion is associated to pre-surgical factors. We therefore suggest that greater preventive and therapeutic efforts be directed preferably to preparation before surgery, especially in patients at high risk.

[Electrolyte balance in major abdominal surgery. IV. Water diuresis under anesthesia and surgery (author's transl)].

12 patients with major laparotomies were studied during anesthesia alone, during three hours of surgery and during the first two hours of recovery. We demonstrated a decrease in plasma potassium and plasma sodium concentration starting with anesthesia and development of a moderate metabolic acidosis. Plasma osmolality was stable during anesthesia and surgery, but slightly decreased in the early postoperative period. Urine formation and osmolar clearance as well as renal sodium and potassium excretion showed a rising tendency during operation, reaching their maximal values in the recovery room. Sodium balance was positive during and after surgery, and sodium retention amounted to about 75% of sodium infused. Urine-to-plasma-osmolality-ratio was 2,0 under anesthesia alone, decreased during surgery and reached control values in the recovery room. In 5 out of 12 patient studied we demonstrated a temporary water diuresis at different points of anesthesia and laparotomy and occasionally even in the postoperative period. This could be due to low plasma levels of ADH caused by relative hypervolemia in the absence of other stimuli of ADH-secretion.
