  • Title: Paravertebral vs epidural block in children. Effects on postoperative morphine requirement after renal surgery.
    Author: Lönnqvist PA, Olsson GL.
    Journal: Acta Anaesthesiol Scand; 1994 May; 38(4):346-9. PubMed ID: 8067221.
    Abstract:
    Continuous thoracic paravertebral blockade (PVB) has only recently been reported in pediatric patients. The aim of the present study was to compare retrospectively the postoperative analgesic efficacy of PVB vs conventional lumbar epidural blockade (EDA) in children. Thirty-five consecutive pediatric patients undergoing renal surgery, receiving either PVB (n = 15) or EDA (n = 20), were reviewed. The need for supplemental morphine administration during the first 24 postoperative hours was used to assess the postoperative analgesic efficacy of the two different regional techniques. Both the total amount of supplemental morphine and the number of patients with no need for supplemental morphine administration, were compared between the two groups. The need for supplemental morphine administration was significantly lower (P = 0.046) and the number of patients with no need for supplemental morphine administration postoperatively was significantly higher (P = 0.019) in patients treated with PVB vs EDA. The present study indicates that PVB may possess a potential for postoperative analgesia equal to or maybe even superior to conventional lumbar EDA in pediatric patients undergoing renal surgery. Further prospective studies investigating the analgesic efficacy of this novel technique are warranted.
