A COMPARATIVE STUDY OF UNILATERAL PARAVERTEBRAL BLOCK VERSUS CAUDAL BLOCK IN CHILDREN UNDERGOING INGUINAL HERNIA SURGERY UNDER GENERAL ANAESTHESIA
Journal Title: Journal of Evidence Based Medicine and Healthcare - Year 2019, Vol 6, Issue 11
Abstract
BACKGROUND Inguinal hernia repair in children is the commonest day-care surgical procedure done in the paediatric age group. Regional anaesthesia and nerve blocks are now widely used in children, mostly in conjunction with general anaesthesia. Caudal analgesia is the most common regional block performed in children due to ease of performance and reliability. Paravertebral blockade has recently been shown to produce long lasting postoperative analgesia when used in combination with general anaesthesia in paediatric herniorrhaphy. The objectives of this study were- 1) to compare the efficacy of caudal and paravertebral blocks in children. 2) to compare intraoperative hemodynamic parameters and analgesic requirements. 3) to compare postoperative pain relief in both the groups. MATERIALS AND METHODS 80 paediatric patients with unilateral inguinal hernia between 2-7 years were allocated into 2 groups of 40 each. Group A received paravertebral block using nerve stimulator at T12-L1 interface, while group B received caudal block using the loss of resistance technique. Statistical analysis- for qualitative data chi square fischer test was used. For quantitative data unpaired t test was used. All analysis was done by SPS statistical method version 16.0. RESULTS Haemodynamic parameters, pain score, incidence of nausea and vomiting were comparable in both the groups. However, duration of postoperative analgesia and urinary retention were found to be significantly different. In Group A mean time for rescue analgesia administration was 11.39 hrs. while for Group B it was 5.32 hrs. (p=0.001). The mean time of voiding urine in group A was 5.32 hours while in group B it was 9.24 hours (p=0.003). CONCLUSION Both the techniques are safe and provide good quality postoperative pain relief. However, the postoperative analgesia was better and the time to void urine was earlier with paravertebral block than with caudal block.
