EFFECT OF PRE OPERATIVE ANXIETY ON SPINAL ANESTHESIA INDUCED HYPOTENSION IN OBSTETRIC PATIENTS

Muhammad Ali Abbas, Syed Ali Raza Ali Shah*, Syeda Sarah Naqvi.

Abstract
Objective: To determine the effect of pre-operative anxiety and post-spinal hypotension in patients undergoing caesarean section.
Study Design: Cross sectional comparative study.
Place and Duration of Study: It was conducted at anaesthesia department AK CMH Rawalakot, over a period of 05 months, from 16th Sept, 2013 to 15th Feb, 2014.
Materials and Methods: One hundred patients were included in the study, using non-probability convenience sampling technique for selection. Direct assessments of preoperative anxiety was done on verbal analogue scale (VAS 010) anxiety score. Patients were then placed in two groups: A and B, depending on VAS score; those with scores 0-5, were placed in Group A, and those with scores between 6-10, were placed in Group B. Patients were preloaded with 10 ml/kg of crystalloid. Baseline Mean Arterial pressure (MAP) was noted by measuring blood pressure thrice, and mean was taken for MAP. Spinal Anesthesia was administered using 0.75% Bupivacaine. Five readings were then taken for blood pressure, 03 minutes apart. Lowest of these was noted down. Hypotension was defined as 20 % drop in MAP from baseline.
Results: Out of 100 patients, 56 were placed in group A and 44 were placed in group B. Out of the 56 patients in group A, 07 (12.5%) patients developed hypotension. Out of the 44 patients in group B, 14 (31.82%) patients developed hypotension. Difference between the two groups was statistically significant (p=0.019).
Conclusion: Pre-operative anxiety is significantly associated with post spinal hypotension in obstetric patients undergoing cesarean section.

Key words: Caesarean section, Hypotension, Spinal Anesthesia, Verbal analogue Score.
