Quality improvement assessment of a bianchi-technique pediatric orchiopexy perioperative pain management pathway.

BACKGROUND

Surgical correction of undescended testes is a common surgical procedure which can be performed via a two-incision technique or a single high scrotal incision (Bianchi technique). The Bianchi technique requires less surgical time and may be associated with less pain in the initial postoperative period, however it has been adopted slowly due to a lack of familiarity and perceived technical challenges of the technique. Traditionally postoperative orchiopexy pain is managed with a caudal or ilioinguinal/iliohypogastric nerve block. As urologists at our site adopted the Bianchi technique, the anesthesiologists stopped performing caudals or ilioinguinal/iliohypogastric nerve blocks as local infiltration appeared sufficient. Therefore, this quality improvement (QI) project endeavoured to assess Alberta Children's Hospital's care pathway in its effectiveness to control pain in the first 24 h following pediatric orchiopexy using the Bianchi technique.

METHODS

We completed a prospective QI project examining a care pathway for patients undergoing orchiopexy using the Bianchi technique. Eligible patients were healthy and aged 6 months to 12 years. A multimodal analgesic approach including local anesthetic surgical infiltration was used. Pain scores (FLACC) were recorded for up to 2 h postoperatively and a PPPM was completed at 24 h postoperatively.

RESULTS

Sixty-four patients were included in the final analysis. The median discharge FLACC score was 0 (range 0-2) (Table 2). Median intraoperative morphine administered was 0.09 mg/kg with no significant correlations between the amount of morphine administered and postoperative pain measures. Median PPPM scores were 4 and 3.5 for unilateral and bilateral procedures, respectively.

CONCLUSIONS

We have demonstrated that orchiopexies repaired using the Bianchi technique following the care pathway established at Alberta Children's Hospital are associated with minimal pain scores. Our QI project suggests that combining a Bianchi technique with a simple multimodal analgesic approach including local infiltration, negates the need for regional anesthesia techniques, yet still provides adequate analgesia.
