Comparison of ondansetron and droperidol in the prevention of nausea and vomiting after inpatient minor gynecologic surgery.
Ondansetron and droperidol are both effective in the prevention of postoperative nausea and vomiting (PONV). In this randomized, double-blind study, 80 inpatients scheduled for minor gynecologic surgery received either ondansetron 8 mg intravenously (i.v.) or droperidol 2.5 mg i.v. 5 min prior to induction of isoflurane-narcotic anesthesia. PONV was absent in 68% of the patients after ondansetron and in 88% after droperidol (P < 0.05). The respective times of complete arousal from anesthesia were 171 min and 229 min (P < 0.001). After ondansetron and droperidol, the incidence of severe drowsiness, restlessness, anxiety, or dizziness was 5% and 28%, respectively (P < 0.01). Thus after minor gynecologic surgery, droperidol 2.5 mg i.v. was superior to ondansetron 8 mg i.v. in the prevention of PONV. However, relative to ondansetron, droperidol entailed an average 1-h delay in recovery from anesthesia.

The effective dose of dexamethasone for antiemesis after major gynecological surgery.
UNLABELLED: This double-blind, randomized, placebo-controlled study evaluated the minimum effective dose of dexamethasone for postoperative antiemesis. One-hundred fifty women scheduled for major gynecological surgery were randomly assigned to receive dexamethasone 10 mg (D10), 5 mg (D5), 2.5 mg (D2.5), 1.25 mg (D1.25), or placebo (P) before the induction of general anesthesia. A standardized general anesthesia technique was used. Postoperative pain was treated with bolus IV doses of morphine via a patient-controlled analgesia device. Patients were assessed for incidence of vomiting at 4, 8, 12, and 24 h after surgery. A total of 6, 6, 8, 15, and 19 patients in Groups D10, D5, D2.5, D1.25, and Group P experienced vomiting at least once within the first postoperative 24 h, respectively. Dexamethasone 10 mg, 5 mg, and 2.5 mg was more effective than dexamethasone 1.25 mg or placebo for antiemesis (P < 0.05). The difference in antiemetic effect among the 10 mg, 5 mg, and 2.5 mg groups was similar. The results suggest that 2.5 mg is the minimum effective dose of dexamethasone for postoperative antiemesis in patients undergoing general anesthesia for major gynecological surgery. IMPLICATIONS: Although dexamethasone is effective for antiemesis, major side effects may accompany its perioperative use. To achieve the best antiemesis with the fewest side effects, dexamethasone 10 mg, 5 mg, 2.5 mg, and 1.25 mg were compared with placebo in surgical patients. We found 2.5 mg to be the minimum effective dose without discernible side effects.

Hysterectomy and incontinence: a study from the Swedish national register for gynecological surgery.
BACKGROUND: Hysterectomy is one factor that has been suggested to be a risk factor for developing stress incontinence. In Sweden, with a population of 8.86 million, a national register was set up in 1997 in order to have data for assessing the quality of gynecological surgery for benign disorders. METHODS: Data in the Swedish national register for gynecological surgery during the period 1997-2002 were investigated. Surgical methods compared during this time period were: total hysterectomy (abdominal/laparoscopic, n=198/116), subtotal hysterectomy (abdominal/laparoscopic, n=163/86), and total hysterectomy (vaginal/laparoscopic assisted vaginal, n=265/7). Patients who underwent endometrial destruction (endometrial ablation, endometrial balloon treatment, n=187) were used as a control group. Only patients with no preoperative complaints were included. Outcome measures were answers to subjective questions asked pre- and postoperatively regarding urinary problems and incontinence. RESULTS: De novo symptoms of stress incontinence, urgency and urgency incontinence, and/or mixed incontinence were noted in all groups. No differences were found among the groups. CONCLUSION: Factors other than hysterectomy should be discussed causing stress incontinence in women.

Management of venous thrombosis and pulmonary embolism after gynecological surgery.
We experienced 23 cases of venous thrombosis after gynecological surgery for the past 12 years at Tokyo Women's Medical University Hospital, representing 0.345 % of all patients. Eighteen of the 23 cases had deep venous thrombosis (DVT) including five cases followed by pulmonary embolism (PE), and five cases had PE without any symptoms of DVT. The main risk factors for thrombosis in these 23 patients were (1) obesity, DM, hyperlipidemia; (2) huge abdominal tumor, severe adhesion; and (3) hemoconcentration, post-treatment of severe anemia. The onset of PE varied from 1 to 3 postoperative days, when the patients started to walk. Five cases had dyspnea, chest pain, and decreased PaO2 levels without leg pain, while five cases showed only calf pain and tenderness with decreased PaO2 levels. PE was confirmed by immediate diagnostic images such as RI venography with ventilation and perfusion lung scan, pulmonary arterial CT, or pulmonary arteriography. Two patients died and eight patients recovered. The best way of managing venous thrombosis might be as follows: (1) identify the risk factors of thrombosis before surgery; (2) perform prophylactic leg exercises in bed and/or active anticoagulant therapy depending on the degree of risk factors; (3) rapid diagnosis with the images; and (4) proper treatment.

Preventing postoperative deep venous thrombosis in gynecological surgery with defibrotide.
This was an open, fully randomized clinical study designed to compare the effectiveness and tolerability of defibrotide and calcium heparin as prophylactic agents for preventing postoperative DVT of the lower limbs in patients scheduled for gynecological surgery for nonmalignant disease (100 cases) or for tumoral pathology (60 cases). Defibrotide was administered by intramuscular injection in doses of 400 mg b.i.d., starting one day before surgery and continuing for seven postoperative days (n = 80); calcium heparin was given by subcutaneous injection in doses of 5000 IU t.i.d., starting two hours before surgery and continuing likewise for seven days (n = 80). DVT was to be diagnosed by computerized impedance plethysmography. Not a single case of DVT occurred in either treatment group; nor were there any significant differences in the magnitude of surgical or postoperative bleeding or in pertinent laboratory test returns. The Authors conclude that defibrotide can be used to advantage instead of calcium heparin as a measure for preventing DVT of the lower limbs in patients undergoing major surgery for gynecologic disorders including malignancy.

Second consultant opinion for elective gynecologic surgery.
Medical records of 516 patients not confirmed for previously recommended elective gynecologic surgery were abstracted. All had participated in the Cornell second opinion elective surgery program between 1972 and 1979. Gynecology was selected because previous analyses consistently have shown that this subspecialty has one of the highest nonconfirmation rates. Moreover, the majority of program participants follow the advice of the second opinion consultant; hence, it was deemed important to look at reasons for nonconfirmation. Findings showed that in 51% of the cases, the consultants believed either that the patient's clinical symptoms were not severe enough to warrant surgery or that further evaluation was needed. In 14.3% of the cases, no pathologic justification for surgery was evident.

Metronidazole in the prophylaxis of anaerobic infections in gynecologic surgery.
A double-blind study was initiated in January 1978 to determine the effectiveness of the prophylactic use of metronidazole, either orally or intravenously, in patients undergoing elective gynecologic surgery. A total of 121 women were evaluated; 42 women received oral metronidazole, 40 women intravenous metronidazole, and 39 women placebo therapy. Evidence of postoperative infection was present in 20% of patients treated with placebo, whereas in the active drug groups the incidence of infection was 12%. Blood levels of metronidazole during the operations had a mean value of 22.2 and 17.9 micrograms/ml for patients receiving intravenous and oral metronidazole, respectively. Preoperative cultures for anaerobic organisms revealed an incidence range of 23% to 45% for the three study groups. The incidence of positive anaerobic cultures declined dramatically by the second postoperative day for patients receiving intravenous and oral metronidazole, In the placebo group, the incidence was not significantly different from that in the preoperative period. This preliminary study revealed that the incidence of postoperative infections subsequent to gynecologic surgery can be reduced significantly through the use of prophylactic metronidazole.

[The optimal dose of fentanyl added to 0.2% ropivacaine for postoperative epidural analgesia after gynecological surgery].
BACKGROUND: Combined administration of local anesthetics and an opioid is frequently used in order to minimize the dose of each drug and to reduce adverse effects. Although fentanyl is commonly administered with local anesthetic, side effects of fentanyl increase in a dose-dependent manner. In this study, we determined the optimal dose of epidural fentanyl after gynecological surgery. METHODS: One hundred and sixteen adult patients scheduled for elective gynecological surgery were divided into 3 groups according to postoperative epidural analgesics; 0.2% ropivacaine (group R), 0.2% ropivacaine with 2 microg x ml(-1) fentanyl (group RF 2), or 0.2% ropivacaine with 5 microg x ml(-1) fentanyl (group RF 5). Each analgesic was infused at 5 ml x hr(-1) for 48 hr. Pain scores , incidence of NSAIDs administration and side effects were recorded for 48 hr after the surgery. RESULTS AND CONCLUSIONS: Ropivacaine alone could not provide sufficient analgesia. Although the addition of 5 microg x ml(-1) fentanyl to 0.2% ropivacaine at a rate of 5 ml x hr(-1) improved postoperative pain, side effects caused by fentanyl increased. Supplementing 2 microg x ml(-1) fentanyl provided sufficient analgesia with the least incidence of side effects.

Patient accept questionnaires integrated in clinical routine: a study by the Swedish National Register for Gynecological Surgery.
BACKGROUND: In 1996, the Swedish National Register for Gynecological Surgery started to collect pre- and postoperative information on patients using questionnaires given out as part of routine medical care. The information is used in providing clinical care to the patient and for quality assessment. AIMS: To evaluate patients' acceptance of questionnaires as a means of collecting information, and to investigate whether the questionnaire is a suitable tool for follow-up of patients. METHODS: In 1998, evaluations of the ordinary questionnaires were done by an evaluation questionnaire mailed to 80 patients who had been recently hysterectomized. The results were triangulated with results from the register's database and data from interviews with physicians and secretaries. RESULTS: The majority of the patients appreciated the questionnaires. Patients did not report any major problems in filling in the questionnaires. Most problems were due to administrative errors of the departments. Up to 36% of the patients missed the scheduled follow-up visit 2 months after the operation. Two out of four departments regarded the follow-up visit necessary and requested by the patients. Out of 1226 patients followed up postoperatively by questionnaire, 75% stated that they did not need any medical care. Among physicians, some distrust of questionnaires was noted. CONCLUSIONS: The patients in this study preoperatively, and for short- and long-term follow-up, accepted the questionnaire as an instrument of data collection. Questionnaires provide a more complete collection of post-treatment information than follow-up visits do. A large number of unnecessary follow-up visits can be avoided through use of a questionnaire.

Effectiveness of defibrotide for prophylaxis of deep venous thrombosis in gynecological surgery: a double-blind, placebo-controlled clinical trial.
Defibrotide, a new antithrombotic compound without anticoagulant activity, has been tested for prevention of deep venous thrombosis (DVT) in patients undergoing gynecological surgery (mainly hysterectomy). Eighty-nine women (mean age 48.5) were randomly allocated to defibrotide (44 patients) or placebo (45 patients). 800 mg defibrotide was given daily (200 mg intravenously 4 times a day), starting on the day before operation and then for the next 7 days. DVT were detected by the conventional 125I-fibrinogen test. The two groups were homogeneous for known risk factors (age, varicosities, obesity, neoplasia and previous thromboembolic episodes). The results showed a statistically significant reduction of DVT incidence in patients on defibrotide, as compared with those on placebo: 4/44 = 9% vs. 13/45 = 28.8% (p less than 0.05). There were no side effects, including hemorrhagic complications. The numbers of units transfused were comparable for the 2 groups. In conclusion, the trial shows that defibrotide is an effective and safe drug for the prevention of DVT in gynecological surgery.

Omission of nitrous oxide from a propofol-based anesthetic does not affect the recovery of women undergoing outpatient gynecologic surgery.
BACKGROUND: Although nitrous oxide (N2O) is used commonly during anesthesia, clinically relevant advantages-disadvantages of using this agent are not well established in the ambulatory setting. This study in women undergoing ambulatory gynecologic surgery compares outcomes in patients administered total intravenous anesthesia with propofol versus the propofol plus N2O. The primary outcome was the time to home readiness. Secondary outcomes included the incidence of postanesthetic adverse events. METHODS: Women presenting for elective ambulatory termination of pregnancy or gynecologic laparoscopy were induced with an intravenous sleep dose of propofol and fentanyl. After induction, subjects were randomly allocated to maintenance anesthesia with propofol alone or propofol plus 65% N2O. Patients were assessed by a blinded observer in the postanesthetic care unit at 20-min intervals to determine home readiness. Postoperative pain and nausea were measured with visual analog scales. Postoperative analgesics and antiemetics were recorded. The incidence of adverse events occurring after hospital discharge was assessed by a telephone interview 24 h postoperatively. RESULTS: A total of 740 patients received propofol alone, and 750 patients received propofol plus N2O. Mean home readiness times were not significantly different between treatment groups. There were no significant differences between groups in pain scores, nausea scores, analgesia administration, or antiemetic administration before discharge. There were no significant differences in the frequency of adverse events for 24 h after discharge from hospital. CONCLUSIONS: Omission of N2O from a propofol-based anesthetic for ambulatory gynecologic surgery does not affect time to home readiness or the incidence of postoperative adverse events up to 24 h after discharge from hospital.

[Roentgenoendoscopic therapy of ureteral injuries after obstetric-gynecological surgery].
Ureteral injuries as a complication of obstetric-gynecological operations occur in 0.37% of cases and are accompanied by formation of stricture or ureteral obliteration, development of uretero-vaginal fistula. Roentgenoendoscopic technologies offer a new solution of the problem of restoration of ureteral passability and elimination of urogenital fistulas. Roentgenoendoscopic treatment of ureteral injuries was made in 14 patients: for obliteration of the lower third of the ureter in 5 cases, stricture of the lower third of the ureter in 9 cases, stricture in combination with uretero-vaginal fistula. The length of the injury varied from 0.2 to 1.5 cm (mean--0.6 cm). Two patients have undergone optic buerginage of ureteral stricture followed by balloon dilation, 7 patients--optic endoureterotomy, 5--ureteral recanalization. Three patients with ureterovaginal fistulas had one-stage fistula fulguration. The operations finished with internal stenting for 6-18 weeks. Normal urine passage recovered in 12 of 14 (85.7%) patients. The fistula disappeared in 3 patients. Thus, roentgenoendoscopic treatment of ureteral injuries after obstetric-gynecological surgery produce positive results in most cases and raises quality of the patients' life.

Pulmonary thromboembolism associated with gynecologic surgery and pregnancy.
Pulmonary thromboembolism continues to be an infrequent but serious complication of gynecologic surgery and pregnancy. The record of each patient with such a complication treated in two community hospitals during the 10 year period to 1976 was examined in detail. An attempt was made to identify weaknesses in past management and suggest changes to improve future care. Embolism will continue to occur unexpectedly and be of such magnitude as to cause death before effective treatment. can be instituted. Patients at risk can often be identified and prophylactic anticoagulants and antibiotics are appropriate in selected cases. An understanding of the pathology of embolism of and principles of genital sepsis combined with vigorous treatment will save some patients who now would die. If the risks are appreciated, anticoagulants may be used in pregnant patients who are closely monitored. These patients must be alerted to the dangers of both embolism and the treatment.

A pain model after gynecologic surgery: the effect of intrathecal and systemic morphine.
BACKGROUND: Despite recent recognition that visceral pain differs from somatic pain in its neurophysiologic basis and treatment modalities, most laboratory studies of postoperative pain use a model of superficial somatic injury, and there is no model of postoperative pain after gynecologic surgery. We describe spontaneous behavior in rats after laparotomy with or without noxious stimulation of the uterus and cervix to more specially address pain after gynecologic surgery. METHODS: Female Sprague-Dawley rats received inhaled anesthesia only, anesthesia with laparotomy, or laparotomy plus 60 min of tonic distension of the lower uterine segment and cervix, followed by video observation of spontaneous behavior. RESULTS: Compared with anesthesia alone, laparotomy decreased some spontaneous behaviors (drinking water, grooming, and exploration). Laparotomy plus uterocervical manipulation further decreased these behaviors and increased abnormal behaviors (licking of the lower abdomen and squashing posture of the pelvis to the floor). Intrathecal and systemic morphine restored spontaneous behavior and reduced abnormal behaviors, with minor differences between routes of administration. CONCLUSIONS: These data suggest that specific behaviors may distinctly reflect somatic and visceral components of postoperative gynecologic pain, and that this model may be used to test novel therapies to relieve pain in this setting.

Pharmacokinetic profile and efficacy of a fentanyl transdermal delivery system for acute postoperative pain after intra-abdominal gynecologic surgery for cancer.
PURPOSE: This prospective, randomized, single-blind study evaluated the efficacy and pharmacokinetic profile of a transdermal delivery system for fentanyl to provide relief of acute postoperative pain in patients undergoing intra-abdominal gynecologic surgery for cancer. METHODS: Forty female patients were randomized to either transdermal fentanyl 50 microg/hour (n = 20) or transdermal placebo (n = 20). Transdermal systems were placed 1 hour preoperatively and removed 25 hours later. Pain control was supplemented with a nonopioid drug, bupivacaine 0.125-0.25%, administered through an epidural catheter via patient-controlled epidural analgesia. Serum fentanyl concentrations, bupivacaine consumption, pain scores [visual analog scale (VAS)], sedation rating score, adverse events, and physiological parameters were recorded for 48 hours postoperatively. RESULTS: The minimum effective concentration of fentanyl in serum (0.63 ng/mL) was achieved at 11.3 +/- 4.9 hours after application, and serum concentrations remained above this level until 13 hours after removal. The TTS-F group had lower VAS pain scores and a significant 66% reduction in utilization of bupivacaine compared with placebo. Pain scores were significantly correlated with serum fentanyl concentration (P = 0.025). All physiological parameters fluctuated within normal range and no differences were observed between treatments. Adverse events were similar between the groups with only the incidence of local erythema significantly higher in the TTS-F group (30% vs. 5%, P < 0.05), and sedation scores were significantly higher in the TTS-F group during the immediate postoperative period. CONCLUSION: The transdermal therapeutic system for administration of fentanyl, combined with epidural administration of a nonopioid analgesic such as bupivacaine is effective in controlling postoperative pain after gynecologic surgery. Additionally, the safety/tolerability of this regimen was similar to placebo plus bupivacaine.

Ketorolac and propofol administration for prevention of nausea and vomiting in patients undergoing minor gynecologic surgery.
This clinical review explores the efficacy of the nonsteroidal antiinflammatory agent, ketorolac tromethamine, added to an anesthetic regimen utilizing intravenous propofol. Both agents have been shown to reduce the incidence of nausea and vomiting postoperatively when administered to patients undergoing minor gynecologic surgery. Because the incidence of nausea and vomiting is significantly reduced when ketorolac is used in place of opioids to attenuate postoperative pain, it would appear to be an appropriate choice of agent to use following propofol anesthesia. The use of this combination of drugs may not only reduce the incidence of postoperative nausea and vomiting in patients undergoing minor gynecologic surgery, but could reduce the duration of hospitalization and enhance recovery from anesthesia.
