Prevalent comparison with normal saline and voluven on distribution of sensory block with bupivacaine hyperbaric in spinal anesthesia in women under elective cesarean section: a double-blind clinical trial

Prelude is one of the ways to overcome the complications of spinal anesthesia. Due to the lack of clarity of the effects of praline on the level of spinal anesthesia, duration and reaching the maximal block and its return, the researchers decided that two normal saline solutions And Voluven in women undergoing elective cesarean section surgery. In this clinical trial study conducted in 1397 with the participation of 70 patients who were candidates for elective cesarean section surgery in Tabriz city hospitals, after selecting the samples, using available sampling method (according to the criteria for entering and leaving the study) Blind random blocks were divided into two groups: A (normal Saline) and B (Voluven). Patients in group A received 10 ml / kg saline from normal saline solution and patients in group B received 5 ml / kg Voluven solution within half an hour before surgery. For parametric variables with normal distribution curve, Independent t test or Unpaired t test and parametric data with abnormal distribution from Mann whitney test and qualitative variables, Chi-square test was used and repeated measures dependent variable test was used in repeated measurements. P <0.05 was considered statistically significant. There were no significant differences between age, sex, weight, BMI between the two groups of Voluven and normal saline. Also, there was a significant difference in the maximum level of spinal block (P = 0.670) in terms of time to reach the maximum level of spinal block (P = 0/973) and there was no relation between the two groups in terms of return time to T10 (P = 0.490). Serum saline and Voluven serum levels can be effective in preventing complications after spinal anesthesia and achieving the maximum level of the spinal block, the time to reach the maximum block level, and the time to return the block.
