Manejo del dolor en el recién nacido postoperado de hernia inguinal con analgesia inmediata al finalizar la cirugía

Abstract

Introduction

The control of post-operative pain in the patient is essential to reduce the clinical and metabolic response that is generated secondary to stress.

Objective

To determine if the administration of analgesia at the end of surgery increases the time of presentation of the pain using the CRIES scale in post-operated bilateral inguinal hernia newborns.

Methods

A randomised double-blind clinical trial was conducted from November 2002 to August 2003, on premature newborn with corrected gestational age of ≥ 37 weeks. In all cases Regional anaesthesia with caudal block was used in all cases. At the end of the surgery, the patients were randomly assigned for analgesia at the end of the surgery. The drug used was nalbuphine at a dose of 100 μg/Kg.

Results

The gestational age at the time of surgery was 37.3 weeks. A value equal to or greater than 4 on the CRIES scale in the first assessment was observed in the study group at 219 minutes, while that in the control group was 147 minutes (P < .01). In the second assessment, a CRIES value of 4 or greater was observed in the study group at 531 minutes, while in the control group it was at 205 minutes (P < .001).

Conclusions

The period of well-being observed in the group of patients who were administered analgesia immediately at the end of the surgery was 531 minutes for an analgesic drug demand, being more than double the time in the control group.
