“Anticipation of Hypotension in Elderly Patients Undergoing Lower Limb Orthopaedic Surgery Following Spinal Anaesthesia Using Randomised Double Blinded Observational Study”
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2019, Vol 18, Issue 3
Abstract
Elderly patients are more prone to develop hypotension due to decreased physiological reserve. Our study aimed at predicting correlation between incidence of hypotension & Perfusion Index. Perfusion index is defined as ratio of pulsatile blood flow to non-pulsatile blood flow measured using pulse oximeter. MATERIAL & METHODS- In our study 100 elderly patients of both the genders, belonging to ASA-1&2, were selected based on baseline Perfusion Index, posted for elective surgery. Group-A-includes patients with Perfusion Index ˃3.5Group-B-includes patients with Perfusion Index ≤3.5Baseline Perfusion Index was noted by another anaesthesiologist, who assigns the group & not involved in the further study. Spinal anaesthesia was performed in sitting position with 23G Quincke᾿s needle in L2-L3 or L3-L4 space with Inj.Bupivacaine 0.5% hyperbaric 10mg + Inj.Dexmedetomidine 10μg added to it. Motor blockade was attained upto T10level. Perfusion Index was noted every 5 minutes for first 20 minutes & every 15 minutes till the end of surgery. Hypotension was defined as MAP <65 mmHg. Statistical analysis was interpretated with Chi-square test, independent sample ttest. RESULTS- The development of hypotension was more observed in group-A patients. There was significant correlation between baseline Perfusion Index >3.5 & number of episodes of hypotension (P <0.05) CONCLUSION- Incidence of hypotension is more when Perfusion Index >3.5 following spinal anaesthesia.
