Comparative StudyAnaesthesia for colonoscopy. An examination of the anaesthesia as an element of risk at colonoscopy.
The importance of anaesthesia as an element of risk at colonoscopy has been examined retrospectively over a 10-year period from 1975 to 1984. The colonoscopic examinations were made by surgical gastroenterologists and anaesthesiologists working in cooperation. In 1242 cases the patients received diazepam/fentanyl anaesthesia during the colonoscopy (Group I) and in 126 cases they received general anaesthesia (Group II). ⋯ The dosing in the patients in Group I averaged: diazepam as premedication 9.2 mg, intravenous diazepam 12.4 mg, intravenous fentanyl 0.14 mg, and the duration of the colonoscopy was 36.5 min. The medication and the duration of the colonoscopy did not vary significantly in the patients with perforation of the large bowel. Our conclusion is that diazepam/fentanyl anaesthesia, administered by experienced staff, is harmless, and that general anaesthesia for colonoscopy did not involve an increased risk of perforation of the large bowel.

Awareness and recall under anesthesia is a complication that appears to be related to the use of muscle relaxants. While little is known about unconscious awareness and its physical and psychological consequences, it is well known that recall can result in traumatic psychological sequelae under certain circumstances. ⋯ In the event of unexpected awareness, the anesthesiologist must deal with the patient in an honest and forthright manner. Failure to do so may lead to dire psychological consequences for the patient and legal consequences for the anesthesiologist.

Randomized Controlled Trial Comparative Study Clinical Trial[Comparative study of general and spinal anesthesia in elderly women in hip surgery].
The choice between regional versus general anaesthesia for elderly patients undergoing hip surgery is debated. It is vitally important to see if the type of anaesthetic administered affects per- and postoperative morbidity and mortality. Seventy women more than 75 yr old suitable for spinal anaesthesia were included in this study. ⋯ In patients having general anaesthesia, 22.9% developed bronchopneumonia as opposed to 8.6% in the spinal anaesthesia group (p less than 0.05). The mortality rate at three months was rather similar in the two groups. It was concluded that, in order to reduce the incidence of postoperative central dysfunction and bronchopneumonia, spinal anaesthesia should be preferred in geriatric patients for lower limb surgery.

Randomized Controlled Trial Clinical Trial
Hemodynamics of the legs and clinical symptoms following regional blocks for transurethral surgery.
In a prospective clinical study we compared the hemodynamics and clinical symptoms following regional blocks and general anesthesia. 115 patients undergoing transurethral resection of the prostate were randomized to spinal (n = 62) and epidural (n = 53) blocks. An additional 10 patients received general anesthesia. Calf arterial flow, determined by strain gauge plethysmography (SGP), was similar pre- and postoperatively in the regional block groups but decreased in the general anesthesia group (p less than 0.05) on the 5th postoperative day compared to the preoperative day. ⋯ Antiembolism stockings offered no hemodynamic or clinical advantages. During the hospital stay (screening by Doppler and SGP) and 3 months of follow-up, no deep vein thrombosis or pulmonary embolism was diagnosed. 3 months after the operation, unspecific pain and/or weakness in the legs were reported by 12 patients in the spinal group, while the epidural group remained asymptomatic (p less than 0.01). We conclude that the predictive value of negative Doppler and SGP findings is good and that spinal and epidural blocks are hemodynamically advantageous as compared to general anesthesia.
