Ultrasound-guided pericapsular nerve group block for postoperative analgesia following hip arthroplast

Our objective was to evaluate postoperative analgesia after ultrasound-guided Pericapsular nerve group block (PENG) in patients undergoing hip arthroplasty surgeries. To compare total post operative analgesic consumption between the two groups and to evaluate patient satisfaction using Likert Scale and Compare adverse effects and complications if any. In this study, two groups of fifty-six hip arthroplasty patients, each with 28 patients, were created. Subarachnoid Block (SAB) was administered to each group using 3 milliliters of 0.5% hyperbaric bupivacaine. PENG block was administered to Group A patients following SAB. Group B did not receive any blocks. Tramadol was given to both groups in the PACU (Postanesthesia Care Unit) as part of a PCA (Patient Controlled Analgesia). The Numerical Rating Scale (NRS) was used to measure pain. Postoperative data also included the total amount of tramadol taken within the first 24hrs, as well as the timing of the first need for an analgesic. There was no appreciable difference observed between the two groups concerning demographic information, surgical type, or length of surgery. In the first 24 hours, the PENG Block group had significantly low NRS pain scores (P < 0.001). The control group consumed significantly more tramadol (348.93 ± 39.00) than the PENG group (237.14 ± 39.89) mg. Similarly, the control group's first analgesic requirement in the PACU occurred significantly earlier (56.79 ± 31.038 min) than the block group's (87.62 ± 42.08 min). The combination of PENG block + PCA Pump with Tramadol demonstrated advantage over PCA Pump with Tramadol alone regarding the management of pain, reduced analgesic consumption, & higher patient satisfaction suggesting its potential utility in improved postoperative pain management.
