Anesthesia, essays and researches
-
Anesthetists used lower doses of fentanyl, successfully with hemodynamic control by titrating volatile anesthetic agents or vasodilators for fast-tracking in cardiac surgery. ⋯ The I-gel airway is well-tolerated by adult patients undergoing cardiac surgery, and requires lower total doses of anesthetics than endotracheal intubation with hemodynamic control and helps in fast-tracking.

A double-blinded randomized controlled study to compare discharge time and patient satisfaction between two groups of patients submitted to open surgeries for abdominal malignancies using segmental thoracic spinal or general anesthesia. ⋯ This preliminary study has shown that segmental thoracic spinal anesthesia can be used successfully and effectively for open surgeries for abdominal malignancies by experienced anesthetists. It showed shorter postanesthesia care unit stay, better postoperative pain relief and patient satisfaction than general anesthesia.

Pregabalin and clonidine have anti-nociceptive properties. This study assesses their efficacy in prolonging the analgesic effect of spinal anesthesia and post-operative analgesic requirement in patients undergoing vaginal hysterectomy. ⋯ Oral pregabalin (150 mg) prolongs the post-operative pain relief after spinal anesthesia but produces less sedation compared with oral clonidine (150 μg).

The thoracic spinal anesthesia was first described in 1909 and recently revised for various surgical procedures. This is a prospective study aims to evaluate the parameters of the thoracic spinal anesthesia (latency, motor block and paresthesia), the incidence of cardiovascular changes and complications comparing low doses of isobaric and hyperbaric bupivacaine. ⋯ The beginning of the block is fast regardless of the solution used. By providing a sensory block of longer duration than the motor block hyperbaric bupivacaine is reflected in a better indication. Thoracic spinal anesthesia provides excellent anesthesia for lower limb orthopedic surgery.

The aim of the present study is to substantiate and compare the quality and extent of nerve block by using intrathecal bupivacaine or extradural bupivacaine alone and in combined spinal-epidural (CSE) technique using smaller dose of intrathecal bupivacaine and extradural injection of a smaller dose of bupivacaine or normal saline. ⋯ Quality of nerve block in combined technique using bupivacaine both intrathecally and extradurally is better and associated with lower side-effect compared with intrathecal heavy bupivacaine or extradural isobaric bupivacaine alone.
