Association Between Gabapentinoids and Postoperative Pulmonary Complications in Patients Undergoing Thoracic Surgery.
(Journal Article;Multicenter Study)
OBJECTIVE: Perioperative gabapentinoids in general surgery have been associated with an increased risk of postoperative pulmonary complications (PPCs), while resulting in equivocal pain relief. This study's aim was to examine the utilization of gabapentinoids in thoracic surgery to determine the association of gabapentinoids with PPCs and perioperative opioid utilization. DESIGN: A multicenter retrospective cohort study. SETTING: Hospitals in the Premier Healthcare Database from 2012 to 2018. PARTICIPANTS: A total of 70,336 patients undergoing elective open thoracotomy, video-assisted thoracic surgery, and robotic-assisted thoracic surgery. INTERVENTIONS: Propensity score analyses were used to assess the association between gabapentinoids on day of surgery and the primary composite outcome of PPCs, defined as respiratory failure, pneumonia, reintubation, pulmonary edema, and noninvasive and invasive ventilation. Secondary outcomes included invasive and noninvasive ventilation, hospital mortality, length of stay, opioid consumption on day of surgery, and average daily opioid consumption after day of surgery. RESULTS: Overall, 8,142 (12%) patients received gabapentinoids. The prevalence of gabapentin on day of surgery increased from 3.8% in 2012 to 15.9% in 2018. Use of gabapentinoids on day of surgery was associated with greater odds of PPCs (odds ratio [OR] 1.19, 95% CI 1.11-1.28), noninvasive mechanical ventilation (OR 1.30, 95% CI 1.16-1.45), and invasive mechanical ventilation (OR 1.14, 95% CI 1.02-1.28). Secondary outcomes indicated no clinically meaningful associations of gabapentinoid use with opioid consumption, hospital mortality, or length of stay. CONCLUSIONS: Perioperative gabapentinoid administration in elective thoracic surgery may be associated with a higher risk of PPCs and no opioid-sparing effect.
