Abstract

After observing a case of lincomycin (LCN)-induced respiratory insufficiency in a patient recovering from d-tubocurarine (DTC) administration, this interaction was studied in cats anesthetized with halothane-nitrous-oxide-oxide-oxygen. The sciatic nerve was stimulated with a 1.6-second tetanci train of 62.5 Hz every 10 seconds. The area under the contraction curve was electronically integrated and recorded. Five control cats received 0.01 mg/kg DTC every 2 minutes until time-tension integral response (TTIR) was zero. Five experimental cats received 10 mg/kg of LCN followed in 10 minutes by 0.01 mg/kg of DTC every 2 minutes until TTIR was zero. Both groups recovered to 50 per cent of control and were given 10 mg/kg of LCN. There was no difference between the slope of the y-intercept of the regression lines for the log-dose response curves for DTC in the two groups. LCN during recovery from DTC had a statist "Intermittent mandatory ventilation in the treatment of patients with chronic obstructive pulmonary disease".

The effects of isoflurane, sevoflurane, and desflurane anesthesia on neurocognitive outcome after cardiac surgery: a pilot study.

BACKGROUND: Inhalation anesthetics such as isoflurane, sevoflurane, and desflurane are widely used in clinical practice; however, there is no study for comparing these drugs in cardiac surgery with respect to postoperative cognitive outcome and S100 beta protein (S100 BP) levels. In this study, we evaluated the effect of sevoflurane, isoflurane, and desflurane anesthesia on neuropsychological outcome and S100 BP levels in patients undergoing coronary artery bypass grafting (CABG) surgery with cardiopulmonary bypass (CPB). MATERIALS AND METHODS: Forty-two male patients were prospectively randomized and classified into 3 groups according to the volatile agents used; isoflurane, sevoflurane, desflurane. All patients had a sufficient education level to participate in neuropsychological testing and a normal carotid Doppler ultrasonography. Blood samples for analysis of S100 BP were collected before anesthesia (T1), before heparinization (T2), 15 minutes into CPB (T3), following protamine administration (T4), postoperatively (T5), 24 hours after the operation (T6), postoperative day 3 (T7), and postoperative day 6 (T8). The neuropsychological tests, including Mini-Mental State Examination (MMSET) and visual-aural digit span test (VADST), were administered 1 day prior to surgery and on the third and sixth postoperative days. RESULTS: The postoperative third and sixth day MMSET scores and third day visual-written subtest scores in the sevoflurane group were significantly lower than in the isoflurane and desflurane groups (P < .05). S100 BP levels increased with the beginning of anesthesia in the sevoflurane and desflurane groups. Although S100 BP decreased to baseline levels on postoperative day 1 in the sevoflurane group, this was significantly higher on the third and sixth days postoperatively in the desflurane group (P < .05). In the isoflurane group, the S100 BP level was significantly higher than the baseline level only after CPB (P < .05). CONCLUSION: Our study suggests that isoflurane is associated with better neurocognitive functions than desflurane or sevoflurane after on-pump CABG. Sevoflurane seems to be associated with the worst cognitive outcome as assessed by neuropsychologic tests, and prolonged brain injury as detected by high S100 BP levels was seen with desflurane.
