OBJECTIVE To evaluate the effects of two different spinal isobaric levobupivacaine doses on spinal anesthesia characteristics and to find the minimum effective dose for surgery in patients undergoing transurethral resection (TUR) surgery. MATERIALS AND METHODS Fifty male patients undergoing TUR surgery were included in the study and were randomized into two equal groups: Group LB10 (n=25): 10...

In order to assess the effect of spinal clonidine on tourniquet pain, 30 patients scheduled to undergo orthopaedic surgery under spinal anaesthesia were allocated randomly to two groups. Patients in group I (n = 15) received 0.5% isobaric bupivacaine 15 mg plus isotonic saline 1 ml. Patients in group II (n = 15) received 0.5% bupivacaine 15 mg plus clonidine 1 ml (150 micrograms). Sensory block...

BACKGROUND The purpose of the present study is to investigate the anesthetic effect of reduced doses of spinal bupivacaine with epidural top ups in comparison with those of spinal bupivacaine and to determine the adequate doses of drugs used during lower extremity surgeries. METHODS SIXTY ADULT PATIENTS WERE RANDOMIZED TO THREE DIFFERENT TECHNIQUE GROUPS: S group (10 mg of spinal bupivacaine)...

background in clinical practice, the level of sensory block in spinal anesthesia in opium abusers is lower than that in non-abusers because of adaptive changes caused by opium use. objectives the aim of this study was to investigate the level of sensory block resulting from the intrathecal administration of 0.5% bupivacaine in opium abuser patients undergoing lower extremity and lower abdominal...

Low-dose bupivacaine can limit the spinal block level with minimal hemodynamic effects and yield a rapid recovery, but sometimes it may not provide adequate anesthesia for surgery. Dexmedetomidine, a selective α2-adrenoreceptor agonist, was shown to be a potent antinociceptive agent when given intrathecally in animals and humans. The purpose of this study was to evaluate the adjuvant effects of...

OBJECTIVE In the current prospective, randomized study, we aimed to compare the effects of low dose selective spinal anesthesia with 5 mg of hyperbaric bupivacaine and single-shot femoral nerve block combination with conventional dose selective spinal anesthesia in terms of intraoperative anesthesia characteristics, block recovery characteristics, and postoperative analgesic consumption. PATI...

The involvement of respiratory system occurs mainly as a result of a high spinal block. Our case describes the unusual effect of mid-spinal analgesia. We encountered bronchospasm in an otherwise healthy patient undergoing inguinal hernia repair under subarachnoid block. The highest level of block was T6. The anxiety of the patient further aggravated the symptoms. This is probably the first repo...
