Randomized Controlled Trial Comparative Study Clinical TrialContinuous pleural infusion of bupivacaine offers better postoperative pain relief than does bolus administration.
To determine whether continuous pleural analgesia offers better postoperative pain relief than does bolus administration in postcholecystectomy patients. ⋯ Continuous pleural analgesia offers better postoperative pain relief than does bolus administration. Pneumothorax was observed in two patients during the study.

Comparative StudySprotte needle for obstetric anesthesia: decreased incidence of post dural puncture headache.
Reports have emphasized the importance of spinal needle tip configuration in the development of post dural puncture headache (PDPH). ⋯ Our data indicate that the Sprotte spinal needle, with its non-cutting tip, results in a significantly lower (p less than 0.05) incidence of PDPH than Quincke cutting-tip needles of smaller gauge.

Low-dose thoracic epidural anesthesia induces discrete thoracic anesthesia without reduction in cardiac output.
The sensory spread and hemodynamic effects of low-dose thoracic epidural anesthesia were closely studied in 13 elective preoperative patients undergoing thoracotomy. An epidural catheter was inserted at the T4-5 or T5-6 intervertebral space and 5 ml 0.5% plain bupivacaine was injected. Cardiac output was measured by suprasternal Doppler method in all patients and also by thermodilution method with a Swan-Ganz catheter in six subjects. ⋯ Central venous pressure increased gradually and significantly, but within the normal range. Pulmonary vascular resistance slightly decreased in 15 minutes and returned to the control level after endotracheal intubation. Thus, low-dose thoracic epidural anesthesia was associated with minimal cardiovascular changes.
