Pain Management in the Recovery Room

REFERENCE: https://pubmed.ncbi.nlm.nih.gov/32129952/

A correct pain management for children in the postoperative recovery room can be determinant. There is plenty of evidence suggesting notable physiological dysfunction related to poor analgesia, in this scenario, and beneficial results of an effective pain management are also well documented. Postoperative pain, for instance, prolongs hospitalization and delays recovery.

Assessing the patient’s pain level is probably the main issue, as it can be challenging or excessively subjective. In contrast to what happens among adults, there is a lack of direct and objective indicators of childrens’ pain severity. Aspects such as behavior, cognitive development and ethnicity add complexity to this evaluation. There can hardly be a satisfactory assessment without an interdisciplinary approach.

In terms of propedeutic signs, clinical observation must include facial expressions, limbs’ motion, posture, agitation level, verbal content and whether or not the infant touches or points the wound. There’s been an effort to systematize these signs through pain scores, such as CHEOPS, FLACC, CHIPPS, FPS, VAP, OPS and MOPS, which can be useful tools. More recent attempts to enclose objectivity to this assessment are notable, including the skin conductance algesimeter and algorithms that evaluate the heart rate variability.

Once correctly diagnosed, pain management in children can more easily be addressed. Fundamentally, basic analgesics, which are widely accessible, such as NSAIDs and paracetamol should be administered, determining an opioid use reduction. Opioid use should be limited to the operative and early postoperative set, in order to minimize risks related to its collateral effects. Patients receiving opioids must be closely monitored. Basic analgesics can be administered orally, intravenously or rectally.
