Tissue penetration of Meropenem in patients undergoing gynecologic surgery.

The purpose of this study was to assess the tissue-penetrating ability of a new beta-lactam antibiotic, meropenem, in 64 patients undergoing elective gynecologic surgery. Patients received a single 500-mg dose intravenously before surgery. Plasma and tissue concentrations of meropenem were highest at approximately 1 hour, and good tissue penetration was seen in the variety of specimens evaluated. The median plasma concentration at approximately 1 hour was 13.3 micrograms/mL. The median fluid and tissue concentrations at approximately 1 hour were as follows: cervix, 8.5 micrograms/g; endometrium, 2.3 micrograms/g; fallopian tube, 1.9 micrograms/g; myometrium, 3.6 micrograms/g; ovary, 2.3 micrograms/g; and uterus, 2.3 micrograms/g. These tissue concentrations exceed the MICs of meropenem for 90% of typical pathogens associated with gynecologic infections. Meropenem readily penetrates gynecologic tissue. A single 500-mg dose provides adequate tissue concentrations for treatment of gynecologic infections caused by susceptible pathogens.

Ureteral injuries during gynecologic surgery: treatment with a minimally invasive approach.

PURPOSE: To report the safety and efficacy of percutaneous nephrostomy and primary antegrade recanalization for treatment of iatrogenic ureteral strictures after gynecologic surgery. PATIENTS AND METHODS: Ten women had symptoms suggestive of ureteral obstruction during the immediate postoperative period (5 days-1 week after surgery). Under analgesia and conscious sedation, standard percutaneous nephrostomy was performed, and a long 7F sheath was placed in the upper ureter. The obstructions were traversed with the aid of a 0.0035-inch Glidewire and a 5F angled Glide catheter (Terumo, Japan). Subsequently, the areas were dilated with angioplasty balloons to a maximum diameter of 7 mm. Finally, an 8F percutaneous internal/external nephroureteral drainage stent was inserted to secure ureteral patency. Follow-up was carried out by serial nephrostomography until removal of the stent and by renal ultrasonography thereafter. RESULTS: Twelve obstructions with a mean length of 1.4 cm (range 0.4-1.9 cm) were managed. The technical success rate was 100%. No major complications occurred, and normal renal function was restored. The mean follow-up was 12 months. In 60% of the patients, a patent ureter was depicted at 1 week, whereas in four patients, repeat dilation of the obstructed segment was required. The stents were removed after a mean period of 4.8 weeks. CONCLUSION: Percutaneous nephrostomy and primary antegrade ureteral balloon dilation is safe and efficacious for treating ureteral injury after pelvic surgery and obviates open surgical manipulations.

[Postoperative analgesia by constant flow injection of lignocaine in obstetrical and gynecologic surgery].

154 surgical patients were given post-operative analgesia by peridural injection at a constant flow in the post-operative period after obstetric or gynecological surgery. These patients received 536.2 +/- 105.3 mu mol.h-1 (145.2 +/- 28.5 mg.h-1) of lignocaine for 46.97 +/- 15.56 h through a catheter omserted between L1-L2. The drug was given in concentrations which varied between: 27.7 to 18.5 m mol.l-1 (0.75 to 0.50 p. 100) depending on the age; and the volume varied between 17.5 to 30 ml.h-1 depending on the height. Satisfactory analgesia in 87 p. 100 of cases allowed all supplementary analgesia to be stopped. The only significant hemodynamic effect was a slight tachycardia (+ 15 p. 100). Two undesirable side effects were noted: a transitory but well-defined (type 2 or 3) motor paralysis, and an accumulation of plasma lignocaine (40 mu mol.l-1 (1.1 microgram.ml-1) at 48 h).

A comparison of the cost-effectiveness of remifentanil versus fentanyl as an adjuvant to general anesthesia for outpatient gynecologic surgery.

The unique pharmacokinetic properties of remifentanil make it a potentially useful adjuvant during general anesthesia for ambulatory surgery. Fentanyl, inexpensive and easy to administer, is the most common opioid used for this purpose. As an adjuvant to general anesthesia for outpatient gynecologic surgery, we questioned if remifentanil was cost-effective as an alternative to fentanyl. Thirty-four patients undergoing gynecologic laparoscopy or hysteroscopy were prospectively and randomly assigned to a standard practice (n = 18) or a study (n = 16) group. Standard practice patients received fentanyl (3 microg/kg) before induction; study patients received remifentanil by continuous infusion (0.5 microg x kg. min(-1) at induction, then 0.2 microg x kg x min(-1)). Sevoflurane was titrated to a Bispectral index value of 40-55. We investigated recovery profiles, patient and health care professional satisfaction, and drug costs. The incidence of rescue antiemetic treatment (2 of 16 vs. 8 of 18; P = 0.013) and the nausea visual analog scale scores during second stage recovery (0.2 vs. 0.6; P = 0.044) were more frequent in the study group. However, the incidence of intraoperative adverse events and other postoperative sequelae, recovery times, pain and nausea visual analog scale scores, opioid analgesic dosage requirements in the postanesthetic care unit, and satisfaction survey responses were similar between groups. Perioperative drug costs per patient were $17.72 more in the remifentanil (vs. fentanyl) group.

[Urologic complications of gynecologic surgery and their treatment in our clinical data].

In 19 women (aged 27-66 years, mean 44.6 years) a retrospective analysis of the urological complications suffered during gynecological surgery was performed. 14 (73.6%) patients had ureteral injuries with concomitant bladder lesions in two. In the remaining 4 (21%) bladder injury only was present including a woman with a simultaneous urethral lesion. In the postoperative period 3 ureteric, 5 vesicovaginal, and one vesicouterine fistula developed. Intraoperative diagnosis followed by immediate surgical repair of the ureteric and bladder lesions was performed in 2 (10.5%) patients only. Except one case ureteral injury was unilateral, and predominantly right-sided (10:5). One patient suffered injury of one of the ureters in a complete ureteral duplication. The most frequent side of ureteral injury was at the level of the uterine artery with complete ligature of the ureter in 10 (71.4%), and partial in 4 (28.6%) patients. Percutaneous nephrostomy as a temporary diversion was performed in 8 (57.1%) patients. Definitive treatment involved simple Paquin ureteral reimplantation in 5 patients, Boari's procedure in 3, and psoas hitch technique once. Ureteral lysis only was sufficient in 3 patients. The surgical treatment including repair of vesical fistulas was in all cases successful.

Anesthesia with alfentanil and methohexitone for short gynecological surgery. A comparison with thiopentone/nitrous oxide.

An anesthetic technique in which alfentanil hydrochloride, an ultra-short-acting opioid, was used as a substitute for N2O/O2 was evaluated in outpatient gynecological surgery. Methohexitone was used as a hypnotic agent. The following parameters were studied: blood pressure (BP) and heart rate before, during and at the end of surgery; the incidence of apnea longer than 20 s at induction; the awakening phase; immediate postoperative complications and later postoperative complications according to a questionnaire, including signs of thrombophlebitis. Eighty-nine patients were randomly allocated to three groups. Twenty-nine patients received alfentanil 7 micrograms/kg plus methohexitone plus O2/air (Group A7). Thirty patients received alfentanil 15 micrograms/kg plus methohexitone plus O2/air (Group A15). Thirty patients received thiopentone 5 mg/kg plus N2O/O2 (Group P, reference group). Neither in the A7-group, nor in the A15-group was there any increase in peroperative BP, while in the P-group both systolic and diastolic BP rose. The awakening phase was significantly shorter in both the A7- and A15-groups compared to the P-group. Apnea of clinical importance was only seen in the A15-group. There were few immediate postoperative complications in all groups, but the incidence of dizziness was significantly higher in the P-group. According to the questionnaire, the overall incidence of complaints the day after surgery was somewhat higher in the P-group. On the other hand, there was a somewhat higher incidence of thrombophlebitis in both A-groups. We may thus recommend the use of a combination of alfentanil 7 micrograms/kg plus methohexitone and air/oxygen for anesthesia in patients subjected to short gynecological procedures.

Granisetron, droperidol, and metoclopramide for the treatment of established postoperative nausea and vomiting in women undergoing gynecologic surgery.

OBJECTIVE: The aim of this study was to evaluate granisetron, droperidol, and metoclopramide for efficacy and safety in the treatment of established postoperative nausea and vomiting after major gynecologic surgery. STUDY DESIGN: One hundred twenty postoperative female patients were monitored for the first 3 hours after anesthesia in the postanesthesia care unit and for the next 24 hours after anesthesia in the ward. Patients who had postoperative nausea and vomiting within the first 3 hours after anesthesia received intravenously, in a randomized double-blind manner, 40 microg/kg granisetron, 20 microg/kg droperidol, or 0.2 mg/kg metoclopramide. Patients were then observed for 24 hours after drug administration. RESULTS: Complete control of established postoperative nausea and vomiting, defined as no emesis and no need for another rescue antiemetic medication, was more frequent among the patients who had received granisetron (88%) than among those who had received droperidol (55%) or metoclopramide (50%) (P <.05). The severity of nausea was less in patients who had received granisetron than in those who had received droperidol or metoclopramide (P <.05). No clinically adverse events were observed in any of the groups. CONCLUSION: Granisetron is more effective than droperidol or metoclopramide for the treatment of established postoperative nausea and vomiting during the first 3 hours after anesthesia in patients undergoing major gynecologic operations.

Postoperative adhesion prevention in gynecologic surgery with hyaluronic acid.

UNLABELLED: Despite improvements in surgical instrumentation and techniques, adhesions continue to form after most procedures. Peritoneal adhesions develop in 60-90% of women who undergo major gynecological operations. This adhesion formation causes significant postoperative morbidity such as bowel obstruction (65%), infertility (15-20%), and chronic pelvic pain (40%). OBJECTIVE: To demonstrate the efficacy of a hyaluronic acid product (Hyalobarrier Gel) for the prevention of adhesions in gynecological surgery. MATERIALS AND METHODS: From October 2000 to July 2002, 18 women from 26 to 41 years old (mean age 33.66) underwent myomectomy via laparotomy as their first abdominal operation. Between August 2001 and May 2003, the patients underwent a second-look laparoscopy (7 women, 38.9%, 15 sites, 42.8%) or a second-look laparotomy (11 women, 61.1%, 20 sites, 57.1%) during which all the 35 sites corresponding to the previous myomectomies were analyzed. During the second-look procedure the presence, localization and severity of adhesions were evaluated using the Operative Laparoscopy Study Group Classification (OLSG) and American Fertility Society Classification (AFSC). RESULTS: All patients underwent a second-look laparoscopy/laparotomy and only five of 18 (27.7%) showed pelvic adhesions in seven sites (20%) of previous myomectomies. No adhesion was found on the previous sites of myomectomies of pedunculated leiomyomas so, excluding those, adhesions were found in seven of 29 sites of myomectomies (24.1%). CONCLUSIONS: The present study emphasizes the need for improved treatments to prevent adhesions, as there is no doubt that adhesions represent one of the major causes of female morbidity.

The radiologic diagnosis of complications following gynecologic surgery: radiography, computed tomography, sonography, and scintigraphy.

673,000 hysterectomies were done in the United States in 1981. The mortality rate of 16.4/100,000 was less than that for appendectomy. Gynecologic surgery, however, is the most common surgical cause of complications related to the urinary tract with the reported incidence varying from less than 1 to 10%. We reviewed the charts of 1403 patients who had 736 abdominal, 315 vaginal and 143 radical or modified radical hysterectomies. Seventy (5%) patients had complications. Thirty-two (2.2%) patients had 35 complications related to the urinary tract. Complications directly related to surgery were grouped into ureteral injuries (13), fistulas (10), post surgical fluid collections (13), and hydronephrosis following radical hysterectomy. Characteristic images obtained by radiography, sonography (US), computed tomography (CT), and nuclear medicine (NM) are presented, and their use in each group of complications is summarized in the conclusion.

Conscious sedation for minor gynecologic surgery in the ambulatory patient. A pilot study.

A conscious sedation regimen consisting of alphaprodine, hydroxyzine, and methohexital together with intensive behavior modification was evaluated in an open pilot study for patients undergoing minor gynecologic surgery. This combination was found to result in hemodynamic stability, satisfactory patient compliance, and patient and surgeon acceptance. Patients were unable to recognize words taught to them just after drugs were administered.Electroencephalogram (EEG) changes seen in general anesthesia or deep sedation were not found in the EEG records of a subset of patients. These findings suggest that conscious sedation can provide adequate relief of pain and anxiety for minor gynecologic procedures when local anesthesia can achieve only partial pain relief.

The antiemetic efficacy of prophylactic granisetron in gynecologic surgery.

Postoperative nausea and vomiting are common after recovery from anesthesia. We examined the prophylactic effect of granisetron on postoperative nausea and vomiting in 120 female patients (ASA physical status I) undergoing gynecologic surgery. They were randomly allocated to one of three groups (n = 40 for each): saline (as a control), granisetron 20 micrograms/kg, and granisetron 40 micrograms/kg. Saline or granisetron was given intravenously (IV) over 5 min approximately 30 min before the end of anesthesia. Nausea, vomiting, and safety assessments were performed during the 24-h recovery period. For the 24-h period after surgery, the number of emesis-free patients was significantly larger in the granisetron groups than in the control group (83%, 78%, and 20% of patients receiving granisetron 20 micrograms/kg and 40 micrograms/kg, and saline, respectively). Granisetron at both doses also was superior to the control for the prevention of nausea over the 24-h study period (nausea visual analog scales at 24-h postsurgery: 49 mm, 17 mm, and 18 mm in the control, granisetron 20 micrograms/kg, and granisetron 40 micrograms/kg groups, respectively). Fewer patients received "rescue" antiemetics in the granisetron groups than in the control group (10%, 10%, and 43% of patients in granisetron 20 micrograms/kg and 40 micrograms/kg, and the control groups, respectively). The adverse events in the granisetron groups were similar to those in the control group. The administration of granisetron had no significant effect on vital signs or clinical laboratory test profiles. Granisetron given at 20 or 40 micrograms/kg i.v. during anesthesia appears to be a simple, effective, and safe method for preventing postoperative nausea and vomiting.

The influence of lockout intervals and drug selection on patient-controlled analgesia following gynecological surgery.

This study systematically compared 2 opioids, morphine (MOR) and fentanyl (FEN), and 2 lockout intervals, long (L) and short (S) in patients utilizing patient-controlled analgesia (PCA). Seventy-eight women undergoing gynecological surgery were randomly assigned to 1 of 4 groups: MOR-S (7 min), MOR-L (11 min), FEN-S (5 min), FEN-L (8 min). PCA measures obtained during the first 24 h after surgery included: number of demands/h, number of completed deliveries/h, dose/h, and demand/delivery ratio. Visual analog scales of pain and anxiety were also obtained. Results indicated that pain relief was equivalent with minimal side effects for both opioids. The selection of opioid, however, influenced the pattern of PCA use, with an improved demand/delivery ratio initially for FEN. The lockout intervals chosen for this study did not influence pain or anxiety levels.

Antinociceptive effect of low-dose intrathecal neostigmine combined with intrathecal morphine following gynecologic surgery.

BACKGROUND: The purpose of this study was to determine whether combination of 1-5 microg intrathecal neostigmine would enhance analgesia from a fixed intrathecal dose of morphine. METHODS: A total of 60 patients undergoing gynecologic surgery were randomized to one of five groups. Patients received 15 mg bupivacaine plus 2 ml of the test drug intrathecally (saline, 100 microg morphine, or 1-5 microg neostigmine). The control group received spinal saline as the test drug. The morphine group received spinal morphine as test drug. The morphine + 1 microg neostigmine group received spinal morphine and 1 microg neostigmine. The morphine + 2.5 microg neostigmine group received spinal morphine and 2.5 microg neostigmine. Finally, the morphine + 5 microg neostigmine group received spinal morphine and 5 microg neostigmine. RESULTS: The groups were demographically similar. The time to first rescue analgesic (minutes) was longer for all patients who received intrathecal morphine combined with 1-5 microg neostigmine (median, 6 h) compared with the control group (median, 3 h) (P < 0.02). The morphine group (P < 0.05) and the groups that received the combination of 100 microg intrathecal morphine combined with neostigmine (P < 0.005) required less rescue analgesics in 24 h compared with the control group. The incidence of perioperative adverse effects was similar among groups (P > 0.05). CONCLUSIONS: The addition of 1-5 microg spinal neostigmine to 100 microg morphine doubled the duration to first rescue analgesic in the population studied and decreased the analgesic consumption in 24 h, without increasing the incidence of adverse effects. The data suggest that low-dose spinal neostigmine may improve morphine analgesia.

[Postoperative pain management using subcutaneous fentanyl and ketamine after abdominal gynecologic surgery].

BACKGROUND: Subcutaneous opioid is one way of managing postoperative pain in patients undergoing anticoagulant therapy. We have evaluated the safety and the efficacy of postoperative pain management using subcutaneous fentanyl and ketamine after abdominal gynecologic surgery. METHODS: Written informed consent was obtained from 50 ASA physical status 1 or 2 female patients aged between 20 and 65. Patients were randomized to one of 5 groups. Group 1, 2 and 3 received 25, 35 and 50 microg x h(-1) subcutaneous fentanyl infusion, respectively. Group 4 received 25 microg x h(-1) fentanyl and 2 mg x h(-1) ketamine subcutaneously; group 5 received 25 microg x h(-1) fentanyl and 4 mg x h(-1) ketamine subcutaneously. General anesthesia was administered to all patients. Two hours after induction, subcutaneous infusion of fentanyl and ketamine was started in the patients and discontinued 24 hours after the operation. All patients were assessed twice, at 4 hours and at 24 hours after operation. Blood gas analysis was performed. Number of analgesic administration required during the 24 hours after operation was recorded. Groups 1, 2, 3 and groups 1, 4, 5 were evaluated as one group, respectively. Group differences were analyzed by variance analysis. Differences of analgesic administration were analyzed with Kruskal-Wallis test. RESULTS: As to anesthetic requirement during the 24 hours after operation, there were no significant differences among treatment groups. With respect to blood gas analysis, only individuals receiving subcutaneous 25 microg x h(-1) fentanyl and 4 mg x h(-1) ketamine maintained high PaO2 4 hours after the operation (P<0.05). CONCLUSIONS: We recommend administration of 25 microg x h(-1) fentanyl and 4 mg x h(-1) ketamine subcutaneously, which maintains high Pao2 and requires less analgesic.

Gonadotropin-releasing hormone analogue therapy for peritoneal inclusion cysts after gynecological surgery.

OBJECTIVE: The purpose of this report is to estimate the effectiveness of gonadotropin-releasing hormone analogue (Gn-RHa) therapy for peritoneal inclusion cysts. METHODS: Patients who had cystic masses that developed after gynecological surgery and were strongly suspected of being peritoneal inclusion cysts based on the results of ultrasound, magnetic resonance imaging (MRI), and tumor marker studies, were treated with a Gn-RHa (buserelin acetate or leuprorelin acetate). Buserelin acetate was administered at a dose of 900 microg/day, and leuprorelin acetate at a dose of 3.75 mg/month. Ultrasonography was performed in the outpatient clinic every 2 weeks after the start of administration to measure the diameter of cysts. RESULTS: We treated 8 patients with peritoneal inclusion cysts conservatively with a Gn-RHa. The cysts resolved in 7 of the patients. Two of them developed a recurrence, but further Gn-RHa therapy was followed by complete resolution of the cysts in one patient and we resume Gn-RHa therapy to the other patient. The peritoneal inclusion cysts failed to shrink in only one patient. CONCLUSION: It is suggested that Gn-RHa therapy is effective in some cases of peritoneal inclusion cysts.

Nalbuphine after major gynecologic surgery. Comparison of patient-controlled analgesia and intramuscular injections.

A randomized investigation compared the efficacy and safety of nalbuphine administered by two methods, a patient-controlled infuser system and intramuscular (IM) injections, after major gynecologic surgery. Forty-seven patients were randomly assigned to receive nalbuphine by either method. The 22 patients using the infuser were given a 2.0-mg, incremental dose with a 10-minute lock-out interval between doses. A similar group receiving 10-15 mg IM every three hours served as the control. Misprogramming, overdosage, depressed respiration and drug dependence were not encountered. Self-administration provided equally satisfactory sedation and more immediate pain relief without painful injections. Although patients with the infuser had the ability to self-administer more medication, they did not use higher doses of nalbuphine than did the IM group. The additional cost of the infuser system was offset by the satisfaction expressed by the patients and by the improved nursing efficiency. Nalbuphine administered with a patient-controlled infuser provided an effective balance between analgesia and sedation and offered advantages over IM injections.

Preoperative coping strategies and distress predict postoperative pain and morphine consumption in women undergoing abdominal gynecologic surgery.

OBJECTIVES: The aim of the present study was to predict postoperative pain and morphine consumption based on preoperative psychosocial factors. METHODS: One hundred and twenty-two women completed measures of distress and coping 1 week before major abdominal gynecological surgery by laparotomy. Forty-eight hours after surgery, measures of pain and negative affect (NA) were completed, and morphine consumption was recorded from a patient-controlled analgesia pump. Four weeks after surgery, measures of pain and NA were completed. RESULTS: Multivariate analyses revealed that preoperative self-distraction coping (P=.039) positively predicted postoperative pain levels in the hospital, after accounting for the effects of age, concurrent NA, and morphine consumption. Emotional support (P=.031) and religious-based coping (P=.036) positively predicted morphine consumption in the hospital, after accounting for the effects of age, concurrent NA, and pain levels. Preoperative distress (P<.04 to .008) and behavioral disengagement (P=.034), emotional support (P=.049), and religious-based coping (P=.001) positively predicted pain levels 4 weeks after surgery, after accounting for the effects of age and concurrent NA. CONCLUSION: The results suggest that preoperative psychosocial factors are associated with postoperative pain and morphine consumption.

Tropisetron for the prevention of postoperative nausea and vomiting in women undergoing gynecologic surgery.

The aim of this study was to evaluate the efficacy of tropisetron, a selective 5-hydroxytryptamine type 3 (5-HT3) receptor antagonist, versus placebo in the prevention of postoperative nausea and vomiting in patients undergoing general anesthesia for gynecologic surgery. Ten minutes before induction of general anesthesia, 80 patients received in a double-blind manner a single intravenous (IV) injection of either 5 mg tropisetron or a matching placebo. Anesthesia was induced with thiopental and maintained with nitrous oxide and enflurane in oxygen. In the first 24 h postoperatively 7 of 40 patients (17.5%) given tropisetron and 16 of 40 patients (40%) receiving placebo vomited (P < 0.05). The incidence of nausea was 30% (12/40) in the tropisetron group and 52% (21/40) in the placebo group (P < 0.05). A total effective antiemetic response showed 26 patients (65%) in the tropisetron group and 16 patients (40%) in the placebo group (P < 0.05). We conclude that tropisetron given IV prior to gynecologic procedures in general anesthesia significantly reduces postoperative nausea and vomiting when compared to placebo without causing any adverse effect.
