Pendant Position and Traditional Sitting Position for Successful Spinal Puncture in Spinal Anaesthesia

Not Applicable

Completed

• Conditions: Pregnancy, Caesarean Section
• Interventions: Procedure: Traditional sitting position; Procedure: Pendant position

• Registration Number: NCT02753660
• Lead Sponsor: Indonesia University

Brief Summary

The aim of this study was to compare the successful spinal puncture among patients with pendant position in comparison with those who used traditional sitting position for caesarean section.

Detailed Description

Approval from Ethical Committee of Faculty of Medicine University of Indonesia was acquired prior conducting the study. Subjects were given informed consent before enrolling the study. Subjects were divided into Group A for traditional sitting position (n=154) and Group B for pendant position (n=154). The outcome parameters recorded were the number of attempt for the successful spinal puncture, the number of spinal needle-bone contact and the duration to perform spinal puncture. Data were analyzed by using Statistical Package for Social Scientist (SPSS) version 21.0. Numerical data was served in median with minimal and maximal value. Numerical data was analyzed by using Mann-Whitney test. Categorical data was served by using relative risk (RR) with 95% confidence interval (95% CI) and was analyzed by using Chi-Square test.

Arm && Interventions

Group	Intervention	Description
Traditional sitting position	Traditional sitting position	Patient is positioned with her knees flexed 90o, both feet hanging of the bed and propped up by a chair, both arms hugging a pillow, adducted pelvic, maximum pelvic flexion were done to create maximal sagittal lumbal flexion before spinal anesthesia begun.
Pendant position	Pendant position	Patients sit with both their underarms propped up on a metal prop, thus both arms hanging from the prop before spinal anesthesia begun.

Primary Outcome Measures

Name	Time	Method
Successful spinal puncture attempt number	2 months	The number of attempt for the successful spinal puncture for each positions
The number of spinal needle-bone contact	2 months	The number of spinal needle-bone contact for each positions
Spinal puncture duration	2 months	the duration to perform spinal puncture for each positions
