Insights
Managing anesthesia in obese children presents challenges due to obesity-related comorbidities. This review details the impact of pediatric obesity on perioperative care and drug dosing for safer anesthesia.
Area of Science:
- Pediatric Anesthesiology
- Obesity Medicine
Background:
- Childhood obesity is rising, increasing the number of severely obese children requiring surgery.
- Obese children often present with comorbidities that elevate perioperative risks.
Purpose of the Study:
- To provide a comprehensive review on the effects of pediatric obesity on perioperative management.
- To offer updated guidance on anesthetic drug dosing for obese children.
Main Methods:
- A narrative review of peer-reviewed manuscripts from MEDLINE and PubMed.
- Inclusion of adult studies when pediatric data was unavailable.
Main Results:
- Obesity in children is defined by age- and sex-specific body mass index percentiles.
- Comorbidities like obstructive sleep apnea, respiratory, and cardiovascular issues are prevalent and increase surgical risk.
- The review discusses the impact of obesity on anesthetic pharmacokinetics and provides dosing recommendations.
Conclusions:
- Safe anesthetic management requires thorough pre-procedure assessment and tailored perioperative care.
- Heightened awareness of complications and individualized drug dosing are crucial.
- Further guidelines are needed for risk stratification, drug dosing, and postoperative care in obese pediatric patients.
Purpose:
Anesthetic management of obese pediatric patients is challenging. With increasing prevalence of childhood obesity, more severely obese children with comorbidities present for surgery every day. The purpose of this review is to provide an up-to-date comprehensive narrative review on the impact of pathophysiological changes imposed by pediatric obesity on the perioperative management of obese children, especially drug dosing. This knowledge is necessary to provide safe delivery of anesthesia for severely obese children.
Source:
MEDLINE and PubMed peer-reviewed manuscripts in obesity and pediatric anesthesia. When there was no information in pediatric literature, we included adult studies in our review.
Principal Findings:
Defining obesity in a growing child is based on body mass index percentiles specific to age and sex. The precursors of adult obesity-related comorbidities are often seen in obese children. Respiratory and cardiovascular comorbidities increase perioperative risk in the severely obese child [>99th percentile]. Obstructive sleep apnea is highly prevalent and requires consideration of opioid sparing techniques and careful postoperative disposition. A detailed discussion on the effect of obesity on pharmacokinetics of different commonly used anesthetics and analgesics is presented, with current recommendations on dosing.
Conclusion:
Optimal and safe anesthetic management of an obese child requires thoughtful pre-procedure assessment and meticulous perioperative management tailored to associated comorbidities, with heightened awareness of potential perioperative complications. There remains a need for improved guidelines for risk stratification, drug dosing and postoperative disposition in this patient population.
