Randomized Controlled Trial Comparative Study Clinical Trial
Serum and urine inorganic fluoride levels following prolonged low-dose sevoflurane anesthesia combined with epidural block.
To determine whether serum and urine inorganic fluoride levels with prolonged (more than 7 hours) low-dose (0.8 to 2.0 vol %) sevoflurane anesthesia plus epidural anesthesia were increased as compared with isoflurane anesthesia plus epidural anesthesia. To measure the urine tubular enzymes N-acetyl-beta-glucosaminidase (NAG), alpha 1-microglobulin (alpha 1-M), and beta 2-microglobulin (beta 2-M) for renal tubular injury in both groups. ⋯ There was no increase in urinary enzymes, which are indicators of tubular injury, specific to sevoflurane. There was no postoperative renal dysfunction, as indicated by unchanged serum creatinine and blood urea nitrogen levels.

Effects of subcutaneous verapamil on the duration of local anesthetic blockade.
To determine whether a subcutaneous injection of verapamil will provide local anesthesia and whether a mixture of lidocaine and verapamil will prolong the anesthetic effect of lidocaine alone. ⋯ Verapamil injected subcutaneously provides a degree of local anesthesia. However, this effect is hampered by a local reaction at the injection site and a short duration of action. The mixture of lidocaine and verapamil provides a shorter duration of action than does lidocaine alone.

Does a mid-lumbar block level provide adequate anaesthesia for transurethral prostatectomy?
In this prospective, randomized study, 23 patients having spinal anaesthesia for transurethral prostatectomy (TURP) were evaluated for the adequacy of their block using a visual analog pain score (VAPS). Each patient with a "standard" (> or = T10) block level (n = 5) or "intermediate" (L1 or T12) block level (n = 5) found the block adequate. Sixty-two percent (8/13) of patients with a "low" (< or = L3) block level found their block adequate. ⋯ However, a smaller (P < 0.05) maximum percent decrease in diastolic blood pressure was found in LBPs, than in "intermediate" or "standard" block patients. It is concluded that a spinal block > or = L1 is adequate during TURP when bladder pressure is monitored and kept low. Mid-lumbar block levels should be reserved for patients in whom the benefit of minimizing haemodynamic changes outweighs the risk of a "less complete" anaesthetic.

Randomized Controlled Trial Clinical Trial
The addition of triamcinolone acetonide to bupivacaine has no effect on the quality of analgesia produced by ilioinguinal nerve block.
In a study of 30 men undergoing elective inguinal hernia repair under general anaesthesia no difference in postoperative pain, patient rating score or morphine consumption was found between patients who had pre-operative ilioinguinal nerve block with bupivacaine 0.5% plain and those who received a similar block with bupivacaine 0.5% plain and triamcinolone acetonide 40 mg. Mean (SD) morphine requirements using a patient-controlled analgesia system were 37 (22.2) mg and 32 (20.3) mg in the bupivacaine and bupivacaine/triamcinolone groups respectively (p > 0.05). The addition of triamcinolone 40 mg to bupivacaine 0.5% offers no advantages over unsupplemented bupivacaine when used for ilioinguinal block.

Clinical TrialInterscalene brachial plexus block for shoulder surgery.
To evaluate the efficacy of interscalene brachial plexus block as the primary anesthetic for shoulder surgery, the influence on blood loss, and the rate of complication. ⋯ Interscalene anesthesia is an effective anesthetic for elective shoulder surgery that may decrease intraoperative blood loss with a low complication rate.
