Insights
Single-stage cleft lip and palate (CLP) repair significantly reduces total anesthetic exposure compared to staged repairs. This approach minimizes anesthesia time, potentially protecting infant neurodevelopment from harmful effects.
Area of Science:
- Pediatric Surgery
- Anesthesiology
- Developmental Neuroscience
Background:
- Cleft lip and palate (CLP) repair often involves multiple surgeries, leading to repeated anesthetic exposure during critical infant neurodevelopment.
- A single-stage repair offers a potential solution to minimize this exposure.
Purpose of the Study:
- To compare total anesthetic exposure between single-stage and staged unilateral CLP repairs.
- To evaluate secondary anesthetic and recovery metrics.
Main Methods:
- Retrospective review of unilateral CLP repairs (2013-2018) at a single institution.
- Comparison of anesthetic data between single-stage (n=86) and staged (n=28) repair groups.
Main Results:
- Single-stage repairs showed a statistically significant decrease in total anesthetic exposure (316 min vs. 345 min, P=0.017).
- Procedure times were similar (260 min vs. 246 min, P=0.224).
- Staged repairs had nearly double the excess anesthesia time (98 min vs. 56 min, P<0.001), mainly during induction.
Conclusions:
- Single-stage CLP repair effectively reduces wasted anesthesia time.
- This approach may mitigate potential neurotoxicity in infants undergoing CLP repair.
Abstract:
Cleft lip and palate (CLP) repair is typically performed in a staged fashion, which requires multiple instances of anesthetic exposure during a critical period of infant neurodevelopment. One solution to this concern includes the implementation of a single-stage CLP repair performed between 6 and 12 months of age. This study aimed to compare total anesthetic exposure between single-stage and staged CLP repairs. A retrospective review of unilateral CLP repairs between 2013 and 2018 conducted at a single institution was performed. Patients underwent either traditional, staged lip and palate repair, or single-stage complete cleft repair, where palate, lip, alveolus, and nasal repair was performed simultaneously. Primary endpoints included: total surgical time and total anesthetic exposure. Secondary endpoints included: excess anesthesia time, recovery room time, length of stay, and type of anesthetic administered. Two hundred twenty-five (n = 225) unilateral CLP repairs were conducted at the Loma Linda University. Detailed anesthetic data for eighty-six (n = 86) single-stage and twenty-eight (n = 28) staged operations were available. There was a statistically significant decrease in anesthetic exposure in single-stage versus staged repairs (316 minutes versus 345 minutes, P = 0.017), despite similar procedure times (260 minutes versus 246 minutes, P = 0.224). This resulted in near double excess anesthetic exposure time in the staged group (98 minutes versus 56 minutes, P < 0.001), primarily occurring during induction. This analysis suggests that single-stage CLP repair can reduce wasted time under general anesthesia and potentially reduce harmful neuronal toxicity in the developmental period in this at-risk population.
