Background: After spinal anesthesia, patients undergoing cesarean section are more likely to develop hemodynamic changes. The baricity of local anesthetic has an important role on spinal blockade effects. The aim of this study was to compare the isobar and hyperbaric bupivacaine 0.5% plus fentanyl on maternal hemodynamics after spinal anesthesia for C/S.Methods: In this double-blind study, 84 h...

BACKGROUND Hypotension during spinal anaesthesia for Caesarean delivery is a result of decreased vascular resistance due to sympathetic blockade and decreased cardiac output due to blood pooling in blocked areas of the body. Change in baseline peripheral vascular tone due to pregnancy may affect the degree of such hypotension. The perfusion index (PI) derived from a pulse oximeter has been used...

OBJECTIVE Spinal anesthesia is commonly used for cesarean section. Its major adverse effect is hypotension. The objective of this study is to determine the incidence and risk factors of hypotension during spinal anesthesia for cesarean section. MATERIAL AND METHOD The authors retrospectively reviewed anesthetic records of 991 patients who received spinal anesthesia for cesarean section at Sir...

When the sensory block level (SBL) is ≥T5 or T4, a high incidence of hypotension occurs in parturients after spinal anesthesia. A rapidly ascending SBL is another risk factor for spinal anesthesia-induced hypotension. However, the relationship between the ascension rate of the SBL and spinal anesthesia-induced hypotension remains unclear.After placement in the left lateral position, combined ep...

background: obtaining a good sensory and motor block is the goal of performing spinal anesthesia for surgeries. the aim of this study is to compare the effect of trendelenburg position on sensory block level after spinal anesthesia with intrathecal hyperbaric bupivacine. methods: we enrolled 80 men, classified as asa i, scheduled for elective hernia repair under spinal anesthesia. participants ...

Background: Hypotension is commonly occurred with Spinal anesthesia. Colloids and Crystalloids are used preoperatively to prevent hypotension. Objective: To examine the effect of fluid (crystalloid vs. colloid) preloading on hemodynamic stability in old patients planned for lower limb orthopedic operations spinal Patients methods: Eighty undergoing surgery under anesthesia were included this wo...

The use of spinal anesthesia for cesarean delivery has increased with the introduction of small-gauge, noncutting spinal needles. Most women in Canada, the United States, Australia, and Europe requiring elective cesarean delivery receive some variation of a spinal anesthetic technique owing to the perceived advantages of a clear end point in locating the subarachnoid space, fast onset of local ...

We compared continuous non-invasive arterial pressure device and intermittent oscillometric arterial pressure measurement in maintaining hemodynamic stability during spinal anaesthesia for cesarean section. One hundred American Society of Anesthesiologists (ASA) I-II parturients undergoing elective cesarean section under spinal anesthesia were included. Based on a random number table, the partu...

Several techniques have been proposed to prevent hypotension in obstetric patients. Ephedrine and phenylephrine are individually used to prevent maternal hypotension; however, each has its own drawbacks. Some researchers have reported that the infusion of combined ephedrine and phenylephrine immediately after spinal anesthesia for cesarean delivery reduces the incidence of maternal hypotension....

Background: Spinal anesthesia-induced hypotension is one of the most complications which can cause many severe maternal and fetal complications. Therefore, prevention treatment spinal in pregnant women undergoing cesarean delivery play an important role. The use vasopressors effective method hypotensive prophylaxis phenylephrine currently first-line vasopressor choice to prevent this complicati...
