Randomized Controlled Trial Clinical TrialAnesthetic quality during cesarean section following subarachnoid or epidural administration of bupivacaine with or without fentanyl.
It is often assumed that subarachnoid administration of local anesthetics produces a more profound blockade than epidural anesthesia. Furthermore, the addition of fentanyl has been reported to increase preferentially intraoperative analgesia. In the present study we set out to study these two issues in a randomized and controlled study with respect to perceived pain and discomfort during surgery and postoperative pain. ⋯ We conclude that subarachnoidal (12.5 mg) and epidural (100 mg) injections with bupivacaine both produced adequate anesthetic quality in women undergoing elective cesarean section. The addition of fentanyl (10 micrograms subarachnoidally or 100 micrograms epidurally) did not significantly improve the quality of these already profound blockades.

Randomized Controlled Trial Clinical TrialIntravenous regional analgesia using morphine. The effect on postoperative pain following total knee arthroplasty.
We hypothesised that any peripheral action of morphine may contribute to improved postoperative analgesia. The aim of this study was to evaluate the analgesic efficacy of morphine administered preoperatively into an exsanguinated limb prior to total knee arthroplasty. ⋯ Intravenous regional analgesia using morphine provides no analgesic advantage over the intramuscular route from 6-24 h postoperatively.

Randomized Controlled Trial Comparative Study Clinical TrialRecovery and outcome after propofol and isoflurane anesthesia in patients undergoing laparoscopic hysterectomy.
Laparoscopic hysterectomy (LH) is expected to provide fast and comfortable recovery, plus an early return to normal daily activities. This study was carried out to compare the outcome after LH in patients anesthetized with isoflurane or propofol. ⋯ It is concluded that both isoflurane and propofol are suitable anesthetics for LH. In this study recovery was not fast enough to make the patients suitable for same-day surgery.

Case Reports Clinical Trial Controlled Clinical TrialOral ketamine therapy in the treatment of postamputation stump pain.
Hyperactivity of N-methyl-D-aspartate (NMDA) receptors may be one of the factors in the maintenance of postamputation stump pain. ⋯ NMDA receptor antagonists may have a potential in the treatment of neuropathic pain, including stump pain.

Changes in pulmonary mechanics during laparoscopic gastroplasty in morbidly obese patients.
Obesity is an important respiratory risk factor after abdominal surgery. Laparoscopic surgical techniques seem beneficial in obese patients in terms of respiratory morbidity, with a faster return to normal respiratory function. However, there is little information about intraoperative respiratory mechanics and about patient tolerance to abdominal insufflation in the morbidly obese. ⋯ These alterations in pulmonary mechanics are less than those observed with comparable degrees of abdominal inflation in non-obese patients, and were well tolerated. From the point of view of intraoperative respiratory mechanics, laparoscopic surgery is safe in morbidly obese patients.
