BACKGROUND Spinal anesthesia is widely used for caesarean section due to its rapid onset, low failure rate, complete analgesia. Addition of intrathecal ketamine and opioids to local anaesthetics seems to improve the quality of block and prolong the duration of analgesia. OBJECTIVES The purpose of this study was to compare the effect of intrathecal ketamine mixed with hyperbaric bupivacaine to...

Background: We assessed whether intrathecal low-dose bupivacaine with dexmedetomidine could reduce the incidence of spinal anesthesia (SA)-related hypotension. Methods: In total, 47 patients undergoing urological or orthopedic surgery under SA were randomized into two groups. SA was induced using 12.5 mg of hyperbaric bupivacaine alone (Group B; n = 24 patients) or 6 mg of hyperbaric bupivacain...

BACKGROUND AND OBJECTIVES Adding subarachnoid clonidine (an alpha -agonist) prolongs the analgesic effect of the combination of sufentanil and isobaric bupivacaine when combined during labor analgesia. The aim of this study was to compare the quality and duration of the analgesia as well as the incidence of side-effects after the addition of subarachnoid clonidine to hyperbaric bupivacaine and ...

PURPOSE To evaluate the efficacy and side-effects of fentanyl and sufentanil combined with hyperbaric spinal bupivacaine in elective cesarean section. METHODS A prospective, randomized, double-blind study with 64 term parturients, distributed into 2 groups according to the opioid combined with hyperbaric bupivacaine 0.5% (10mg): GF - fentanyl (25 µg) and GS - sufentanil (5.0 µg). The latency ...

BACKGROUND AND OBJECTIVES Shivering is a cause of discomfort and dissatisfaction in patients undergoing cesarean section. The objective of this study paper was to assess the impact of intrathecal administration of sufentanil on the incidence of shivering after cesarean section. METHOD In a prospective blinded, randomized clinical trial, pregnant women undergoing cesarean section under spinal ...

Shivering associated with spinal anesthesia during Cesarean delivery is an uncomfortable experience for the parturient, which may also cause adverse effects. In this prospective, randomized, double-blind, placebo-controlled study, we sought to evaluate the effect of intrathecal dexmedetomidine, administered as an adjunct to hyperbaric bupivacaine for Cesarean delivery, on the incidence and seve...

BACKGROUND Subarachnoid administration of opioids such as pethidine and fentanyl had been proven safe but that oftramadol has been controversial. Tramadol is cheap and readily available, hence the need to further evaluate its intrathecal safety. PURPOSE The study aimed at determining the hemodynamic and side effect profile of intrathecal tramadol. METHODS One hundred and eighty six (186) AS...

a b c d d Aims: This randomized double blind study was carried out to investigate effect of intrathecal fentanyl on incidence and severity of intraoperative shivering on patients undergoing lower abdominal surgeries under spinal anesthesia. Method: 120 patients undergoing lower abdominal surgeries under spinal anesthesia were assessed in a randomized fashion. They were divided in to two groups....
