POSTOPERATIVE PAIN MANAGEMENT OF PATIENTS UNDER- GOING MODIFIED RADICAL MASTECTOMY USING PECTORALIS NERVE BLOCK: COMPARISON OF ROPIVACAINE VS ROPIVACAINE WITH DEXMEDETOMIDINE CASE SERIES

Abstract

Aim: The aim of the present study was to compare Pectoralis nerve block using Ropivacaine
and Ropivacaine with dexmedetomidine for postoperative analgesia in case of modified radical mastectomy, with respect to time for first analgesic requirement and total rescue analgesia consumption in the first 24hrs.
Methods: Ten patients were enrolled for the study. All patients of female sex, belonging to
ASA II and ASAIII, undergoing elective modified radical mastectomy were included. All the
patients were administered Pectoralis nerve block. 10 patients were randomized into two
groups: GROUP R and GROUP RD, to receive either Ropivacaine or Ropivacaine with
dexmedetomidine respectively.
Results: Vitals of all 10 patients were measured at intervals of 0mins, 5mins, 10mins, 15mins
30mins 60mins, 120mins and 180mins after giving the block and also the end of the surgery.
Patients belonging to Group RD showed less variability of heart rate when compared to Group
R. Patients belonging to Group RD showed less variability of systolic blood pressure, when
compared to Group R. Patients belonging to Group RD showed less variability of diastolic
blood pressure, when compared to Group R Group.
Conclusion: As per our study design, we concluded that Ropivacaine with dexmedetomidine
used in PEC block along with general anaesthesia provided effective anaesthesia for modified
radical mastectomy. It prolonged the duration, provides high quality of analgesia, and the
incidence of nausea and vomiting was less.
