A Systematic Review of Caudal Anesthesia and Postoperative Outcomes in Pediatric Cardiac Surgery Patients.

Abstract

OBJECTIVES:

In pediatric cardiac surgery, does caudal anesthesia promote early extubation, reduce pain scores, reduce stress responses, and length of stay (LOS)?

DESIGN:

A systematic review.

PARTICIPANTS:

Inclusion criteria included cardiac surgical procedures (with or without cardiopulmonary bypass) in any subject between the ages of full-term newborn and 18 years receiving caudal anesthesia of any medication combination. Searches were conducted with assistance of an Academic librarian from 1947 to July 2017.

METHODS:

Relevant studies selected were randomized trials or cohort studies.

RESULTS:

The total number of patients was 2159 in 17 studies. There were 8 prospective randomized clinical trials and 9 cohort studies. Caudal medications included dexmedetomidine, bupivacaine, sufentanil, morphine, fentanyl, and neostigmine. Nine studies reported earlier extubation in patients with caudal anesthesia. Cardiopulmonary bypass and surgical duration mitigated early extubation anesthetic strategies. Three of 5 studies showed reduced pain scores and need for opiates, 2 studies showed no difference. Two of 3 studies showed a reduction in stress response. Hemodynamic assessments were improved in 2 studies and unchanged in 3 studies. Four studies showed reduced hospital LOS. Studies are difficult to interpret because of the comparative techniques used.

CONCLUSIONS:

The data quality in this review is too poor to make recommendations regarding incorporation of caudal anesthesia into clinical practice. Caudal anesthesia may be favorable for early extubation, improved pain, and hemodynamics and reduced LOS. There are many other anesthetic alternatives to facilitate early extubation. Our review is limited by heterogeneous populations, variable pain measurement scales, and absent definitions of extubation indicators.
