Lung transplantation has become an accepted therapeutic option for a select group of children with end‐stage lung disease. We evaluated the impact of early extubation in a pediatric lung transplant population and its post‐operative outcomes. Single‐center retrospective study. PICU within a tertiary academic pediatric hospital. Patients <22 years after pulmonary transplant between January 2011 and December 2016. A total of 74 patients underwent lung transplantation. The primary pretransplantation diagnoses included cystic fibrosis (58%), pulmonary fibrosis (9%), and surfactant dysfunction disorders (10%). Of 60 patients, 36 (60%) were extubated within 24 hours and 24 patients after 24 hours (40%). A total of seven patients (11.6%) required reintubation within 24 hours. Median length of stay for the early extubation group was shorter at 3 days ([(IQR) 2.2‐4.7]) compared to 5 days (IQR, 3‐7) (P = .02) in the late extubation group. Median costs were lower for the early extubation group with 13,833 US dollars (IQR, 9980‐22,822) vs 23 671 US dollars (IQR, 16 673‐39 267) (P = .043). Fourteen patients were in the PICU prior to their transplantation; this did not affect their early extubation success. Neither did the fact of requiring invasive or non‐invasive mechanical ventilation before transplantation. Early extubation appears to be safe in a pediatric population after lung transplantation and is associated with a shorter LOS and decreased hospital costs. It may prevent known complications associated with mechanical ventilation.
Although infection is the leading cause of death in the first year following pediatric lung transplantation, there are limited data on risk factors for early infection. Sepsis remains under-recognized and under-reported in the early post-operative period for lung transplant recipients (LTR). We evaluated the incidence of infection and sepsis, and identified risk factors for infection in the early post-operative period in pediatric LTRs. A retrospective review of medical records of LTRs at a large quaternary-care hospital from January 2009 to March 2016 was conducted. Microbiology results on days 0-7 after transplant were obtained. Sepsis was defined using the 2005 International Pediatric Consensus Conferencecriteria. Risk factors included history of recipient and donor infection, history of multi-drug resistant (MDR) infection, nutritional status, and surgical times. Among the 98 LTRs, there were 22 (22%) with post-operative infection. Prolonged donor ischemic time ≥7 hours, cardiopulmonary bypass(CPB) time ≥340 minutes, history of MDR infection and diagnosis of cystic fibrosis were significantly associated with infection. With multivariable regression analysis, only prolonged donor ischemic time remained significant (OR 4.4, 95% CI: 1.34-14.48). Further research is needed to determine whether processes to reduce donor ischemic time could result in decreased post-transplant morbidity.
Background Despite successes in lung transplantation, with infection as the leading cause of death in the first year following lung transplantation, there remains a lag in survival compared with other solid organ transplants. Infections that occur early after transplantation may impact short- and long-term outcomes in pediatric lung transplant recipients (LTRs). Methods We performed a retrospective review of pediatric LTRs at a large quaternary-care hospital from January 2009 to March 2016 to evaluate both epidemiologic features of infection in the first 30 days post-transplantation and mortality outcomes. The 30 days were divided into early (0–7 days) and late (8–30 days) periods. Results Among the 98 LTRs, there were 51 episodes of infections. Cystic fibrosis (CF) was associated with early bacterial infections (P = .004) while non-CF was associated with late viral (P = .02) infections. Infection after transplantation was associated with worse survival by Kaplan-Meier analysis (P value log rank test = .007). Viral infection in the late period was significantly associated with 3-year mortality after multivariable analysis (P = .02). Conclusions Infections in pediatric LTRs were frequent in the first 30 days after transplant, despite perioperative antimicrobial coverage. The association of 3-year mortality with late viral infections suggests a possible important role in post-transplant lung physiology and graft function. Understanding the epidemiology of early post-lung transplant infections can help guide post-operative management and interventions to reduce their incidence and the early- and long-term impact in this population.
