Comparison of Pendant versus Traditional Sitting Position for success rate of spinal anesthesia with sprotte needle on obese partiurent undergoing cesarean delivery: A randomized controlled trial

Abstract

Due to the technical problems of spinal anesthesia in obese people and the lack of a study comparing the effect of pendent position and sitting position in obese mothers under cesarean section, so we decided to examine the success rate of spinal puncture between two positions of pendent and sitting in obese mothers who were reffred to Al-Zahra Hospital for undergoing cesarean delivery. Materials and Methods: This clinical trial study was conducted with the participation of 100 obese pregnant mothers who were candidates for elective cesarean section who had referred to Al-Zahra Hospital in Tabriz in 1997. The samples were divided into two groups of 50 people. The mothers of the intervention group were placed in the pendant position for spinal anesthesia and the mothers of the control group were placed in the usual sitting position. Information and success rate of spinal puncture, vital signs and anesthesia complications in both groups were compared with independent t-test, Pearson correlation and Spearman correlation. Results: In this study, the mean time required for spinal puncture (P = 0.000) and the number of needle-to-bone contacts (P = 0.026) in the conventional sitting group were significantly higher than the pendant group. The success rate in the first needle insertion attempt (P = 0.007) in the pendant group was significantly higher than the conventional sitting group (50% success vs. 24%). Also, the two groups did not differ significantly in terms of changes in vital signs, incidence of anesthesia, duration of anesthesia and surgery.
