Adenotonsillectomy (T&A) is a very common surgical procedure in children. With the rising prevalence of childhood overweight and obesity, our goal was to describe the prevalence of overweight/obesity in children presenting for T&A in our institution. We also sought to compare the frequency of peri-operative complications and the likelihood of being admitted following T&A between overweight/obese and normal weight children.
We examined our peri-operative database and extracted clinical, demographic and anthropometric information on 2170 children who underwent T&A between January 2005 and February 2008. Children were classified into normal weight, overweight and obese using published body mass index (BMI) criteria. The incidences of peri-operative complications were compared between the BMI categories. We also examined factors contributing to the likelihood of admission following T&A.
The overall prevalence of overweight and obese was 20.7%. Overweight/obese children were more likely to have intra-operative desaturation (p=0.004), multiple attempts at laryngoscopy (p<0.001), difficult mask ventilation (p=0.001), and post-induction and post-anesthesia care unit (PACU) upper airway obstruction (p<0.001). Additionally, overweight and obese children were more likely to be admitted following T&A. BMI showed a moderate positive correlation with post-operative length of stay (LOS). Multiple logistic regression analysis showed that BMI and presence of medical co-morbidities were independent predictors of LOS.
Overweight and obese children presenting for T&A have a higher incidence of peri-operative complications and are more likely to be admitted and stay for longer than their healthy weight peers.

    ABSTRACT: Our knowledge of the pharmacology of the drugs used in pediatric anesthesia has advanced with a greater understanding of their pharmacokinetics (PK) and pharmacodynamics. This has resulted in a refinement of their uses, broader indications, and alternative methods of delivery. For example, methadone is becoming increasingly popular for spinal surgery, the dosing of etomidate has been clarified and the PK of intravenous acetaminophen from neonates to adults has been revealed. Morphine PK have also been clarified, although pharmacodynamic ethnic differences remain unexplained. The optimal size descriptor to predict correct drug doses in the obese remains controversial. Efforts to reduce adverse effects of individual drugs have spawned investigations into beneficial drug interactions, although combinations such as propofol and ketamine await PK and safety review. The nasal route may be a reasonable alternative to intravenous administration for many drugs. Oral ketamine may serve as a valuable premedication for children suffering burns. Expanded indications can have unfavorable consequences; propofol may cause profound hypotension in neonates.

    ABSTRACT: Diabetic autonomic neuropathy (DAN) is common complication of diabetes mellitus (DM), associated with development of angiopathies and increased mortality. The objective of the study was to determine the frequency of DAN in type 1 DM patients using heart rate variability (HRV) analysis and, besides, to study the relationship between DAN and circadian profile of blood pressure (BP) and vascular diabetic complications. Power spectral analysis of HRV is found to be a useful method for early detection of autonomic neuropathy in diabetes patients. Dysfunction of autonomic nervous system in type 1 DM patients is associated with increased systolic BP and with reduced fall in nocturnal systolic BP. Through the changes in hemodynamics autonomic neuropathy may contribute to development of diabetic vascular complications.
