Paravertebral block during cholecystectomy: effects on circulatory and hormonal responses.
نویسندگان
چکیده
Surgical trauma induces a hormonal metabolic response which is partly responsible for postoperative catabolism. In this study 12 patients underwent cholecystectomy during isoflurane anaesthesia, six with a paravertebral block (PVB) in addition. Plasma concentrations of glucose, cortisol and adrenaline, and heart rate and arterial pressure were compared between the two groups. The patients with PVB showed a significantly diminished response to noxious stimuli.

Single Dose Preemptive Thoracic Paravertebral Block For Postoperative Pain Relief After Cholecystectomy
The controversy over pre-emptive analgesia continues unabated, with studies both supporting and refuting its efficacy. Forty patients undergoing elective open cholecystectomy were randomized into two equal groups (20 patients each) to either pre-emptive thoracic bolus paravertebral block (PVB) with ropivacaine 0.5% (20 ml), before surgical incision (group I) or to receive the same block after t...
متن کاملEfficacy of single-injection unilateral thoracic paravertebral block for post open cholecystectomy pain relief: a prospective randomized study at Gondar University Hospital
BACKGROUND Cholecystectomy can be associated with considerable postoperative pain. While the benefits of paravertebral block (PVB) on pain after thoracotomy and mastectomy have been demonstrated, not enough investigations on the effects of PVB on pain after open cholecystectomy have been conducted. We tested the hypothesis that a single-injection thoracic PVB reduces pain scores, decreases opio...
متن کاملHigh- and low-dose fentanyl anaesthesia: circulatory and plasma catecholamine responses during cholecystectomy.
The cardiovascular and neuroendocrine effects of a high-dose fentanyl anaesthesia (100 micrograms/kg body weight) were compared with those of a balanced type of fentanyl anaesthesia (5 micrograms kg-1) during upper abdominal surgery. High-dose fentanyl anaesthesia prevented the increase in catecholamine concentrations and attenuated the circulatory response to surgical stress seen in the group ...
متن کاملParavertebral block for post-cholecystectomy pain relief.
Sir,—Thank you for the chance to comment on the letters concerning the editorial "Airways Revisited". I did not state that transtracheal ventilation is unethical, all I said was that it may be considered so in normal patients. Injection of local anaesthesia does not need the great pressure that oxygen requires delivered through the cricothyroid membrane cannula. I do not use blind nasal intubat...
متن کاملSubdural spread of local anesthetic agent following thoracic paravertebral block and cannulation.
THORACIC paravertebral block has been shown to be effective for surgical anesthesia when the afferent pain input is predominantly unilateral from the chest. We describe a patient scheduled for right thoracotomy with combined paravertebral–general anesthesia who had abnormal responses to local anesthetic injection administered via the paravertebral catheter. The catheter subsequently was found t...
