简要总结
Background: Various factors including anthropometric measurements are known to affect the
cephalad spread of spinal anaesthesia. Out of these, certain anthropometric values can be easily
measured and are helpful in predicting the level of sensory block after giving spinal
anaesthesia.
Aim: The Aim of our study is to evaluate the correlation between hip/shoulder width ratio and
intrathecal spread of hyperbaric bupivacaine.
Settings and Design: This Prospective observational study will be conducted at Deen Dayal
Upadhyay Hospital, New Delhi after obtaining approval from the Scientific Research
committee, Institutional Ethics Committee and written informed consent of participating
patients.
Material and Methods: One hundred eleven patients fulfilling the inclusion criteria
undergoing infraumbilical surgeries under spinal anaesthesia will be enrolled in the study.
Preoperatively from the back side, hip-width of the patient will be measured between the two
iliac crests, shoulder-width will be measured between the two acromion processes and vertebral
column length will be measured between C7 vertebra and sacral hiatus with the patient in sitting
position. Patient age, sex, height and weight will also be recorded. Using a 25G Quincke’s
needle, 3 ml of 0.5 % hyperbaric bupivacaine will be administered intrathecally to the patient
in a lateral decubitus position at L3-L4 interspace. The cephalad spread of spinal anaesthesia
will be assessed using loss of pinprick sensation at 5 minute intervals till 30 minutes after
intrathecal injection. The level of spread 30 minutes after intrathecal injection will be used for
analysis.
Statistical Analysis: Spearman/Pearson correlation coefficient and multivariate linear
regression model will be used for the analysis of correlation between study factors and level of
sensory block.
Conclusion: This study will be helpful in evaluating the correlation between hip/shoulder –
width ratio and spread of spinal anaesthesia in Indian population.
