Effect of Obesity on the Recovery Profile After General Anesthesia in Children: A Prospective Cohort Study.

BACKGROUND: Obesity has become a serious problem not only in adult patients but also in pediatric patients. AIM: To evaluate whether obesity affects the recovery profile after general anesthesia in children. PARTICIPANTS: 40 children (aged 2-12 years) who underwent surgery under general anesthesia and had an American Society of Anesthesiologists (ASA) physical I and II. METHODS: This prospective cohort study was conducted over a period of 3 months (January- April, 2021). The patients were divided into two groups according to body mass index (BMI): Group I comprised obese children (BMI ≥95th for age percentile) (n=20) and Group II comprised children with a normal BMI (25-75th for-age percentile) (n=20). Anesthesia induction and maintenance were performed as per standard guidelines in both the groups. OUTCOME: The recovery profile was evaluated with the following parameters: time to spontaneous ventilation, laryngeal mask airway removal time, time to open eyes, and post-anesthesia care unit discharge time. RESULTS: When the recovery profiles were compared, no significant differences were found between the groups. Time to spontaneous ventilation [mean difference (95% CI); 0.66 (0.09-1.42); P=0.085], laryngeal mask airway removal time [MD (95% CI); 1.12 (0.06-2.22); P=0.057), time to open eyes [MD (95% CI) 0.66 (0.40-1.74); P=0.217], and post-anesthesia care unit dis-charge time [MD (95% CI) 3.60 (0.59-7.25); P=0.054] were higher in Group II; however, these differences lacked both statistical and clinical significance. CONCLUSION: The results suggest that obesity has no effect on the recovery profile after general anesthesia in children in our setting.

Left femoral vein is a better choice for cannulation in children: a computed tomography study.

BACKGROUND: Central venous catheters are often required in emergency rooms and intensive care and/or those undergoing major surgical procedures. In this study, we aimed to gain a better understanding of the anatomy of the femoral vessel in relation to central venous cannulation. METHODS: The right and left (total of 180) femoral veins (FVs) of 90 consecutive pediatric patients were retrospectively evaluated using computed tomography images. Patients were divided into two groups according to their age: group 1, patients up to 9 years of age; and group 2, patients between 9 and 16 years of age. RESULTS: The position and overlap of femoral artery (FA) to FV are significantly different between the left and right sides in both groups (P = 0.001). The left FV was most commonly located medial to the FA. However, the right FV was most commonly located posterior-medial to the FA. The incidence of overlap of the FA over the FV was significantly lower at the left side in both groups. CONCLUSION: The incidence of overlap of the FA over the FV was significantly lower at the left side in pediatric patients. This finding was similar between the patients aged 2-8 years and those aged 9-16 years and may have significant clinical implications. Guiding clinicians to select the left FV of children for cannulation may result in lower arterial puncture rates while accessing the central vein.
