Systemic postoperative pain management following minimally invasive pectus excavatum repair in children and adolescents: a retrospective comparison of intravenous patient-controlled analgesia and continuous infusion with morphine.
OBJECTIVE
Optimal postoperative pain management following minimally invasive surgical repair of pectus excavatum is not established. We compared efficacy and adverse effects in patients treated with patient-controlled analgesia (PCA) with those treated with continuous infusion (CI) with morphine in addition to nonsteroidal anti-inflammatory drugs.


METHODS
33 patient records were examined retrospectively: 21 given PCA and 12 CI with morphine. Main outcome variables were used doses of morphine, pain scores every 3 h and adverse effects.


RESULTS
Median (range) used morphine dose was 0.58 (0.21-1.12) and 0.52 (0.34-0.84) mg/kg on the day 1 and 0.3 (0.02-0.6) and 0.33 (0.09-0.53) mg/kg on the day 2 in PCA and CI groups, respectively (p > 0.05). Pain scores were within moderate and low levels during 42 h after surgery and did not differ between the groups. Median (range) oxygen saturation was 96.5 (93-100) and 97 (94-100) in PCA and CI groups, respectively (p > 0.05). Additional oxygen therapy was required in 14.3% in PCA group and 25% in CI group (p > 0.05). The incidence of pulmonary adverse effects was rare and did not differ between the groups.


CONCLUSIONS
Both methods of systemic analgesia in addition to non-opioid analgesics were equally effective and resulted in a low incidence of pulmonary adverse effects.
