OBJECTIVE: To review the incidence and complications of conservative management of bilateral diaphragm paralysis following pediatric cardiac surgery. DESIGN AND SETTING: Retrospective clinical review based on computerized database with daily follow-up in a pediatric cardiac intensive care unit in a tertiary care center. PATIENT AND PARTICIPANTS: Were reviewed the data on nine patients with bilateral diaphragm paralysis from the 3,214 consecutive children (0.28%) after operations performed between 1995 and 2004. MEASUREMENTS AND RESULTS: A fluoroscopy-confirmed diagnosis of bilateral diaphragm paralysis was made in all nine patients. Mechanical ventilation was required for 14-62 days; maximum time to recovery was 7 weeks. Three patients underwent unilateral plication. Patients with a complicated postoperative course required longer mechanical ventilation. All patients were managed with a nasotracheal tube. One patient had minor subglottic stenosis. All patients survived. CONCLUSIONS: Bilateral diaphragm paralysis can be managed conservatively with good prognosis and minor complications. The recovery time is relatively short, less than 7 weeks.
OBJECTIVE: We examined the clinical impact of diaphragmatic palsy (DP) as a result of phrenic nerve injury following cardiothoracic surgery, specifically its effects on morbidity and mortality, early regeneration capacity of the phrenic nerve, and role of surgical diaphragmatic plication. METHODS: A retrospective case control study was performed in 74 children with DP and 74 matched controls after cardiothoracic surgery within the past 14 years. RESULTS: Following 5,128 surgical procedures in children (aged under 18 years) we found an incidence of DP of 1.4%. There were no differences in mortality between the groups, and the cause of death was not related to DP or plication in any of the patients. However, patients with diaphragm impairment had significantly longer duration of mechanical ventilation (median 3 days vs. 1), ICU stay (7 days vs. 3.5), duration of hospital stay (16 days vs. 12), and for antibiotic treatment (16 days vs. 7). Because of prolonged respiratory problems 40 children (54%) underwent surgical diaphragmatic plication to flatten the diaphragm in its inspiratory position. In children with DP younger age was a strong predictor for plication (median 3.8 months vs. 12.1). CONCLUSIONS: Especially in newborns and young infants with DP the length of mechanical ventilation, ICU stay, and hospital stay are prolonged. Early spontaneous recovery of the phrenic nerve is rare. In cases of respiratory impairment early transthoracic diaphragmatic plication is an effective means of treatment.
