Postoperative complications of pediatric dental general anesthesia procedure provided in Jeddah hospitals, Saudi Arabia

Abstract Background Review of post-operative morbidity reports for pediatric dental care under general anesthesia (GA) show great variations. Until now, no morbidity data has been available to estimate the safety of pediatric patients under GA for dental rehabilitation in Saudi Arabia. The purposes of this study were to (1) investigate post-operative complications associated with dental care under GA and (2) correlate morbidity reports with patient's characteristics, dental procedures, and hospital protocol. Methods Study sample included 90 children attending GA for dental treatment at major governmental hospitals in Jeddah. Data were collected from every patient on three occasions, intra-operatively at the operating room, and post-operatively via phone calls in the first and third days after operation. Results Results showed that 99% of the children had one or more complaints in the first day in contrast to only 33% in the third day. Inability to eat (86%), sleepiness (71%), and pain (48%) were the most common complaints in the first day, followed by bleeding (40%), drowsiness (39%), sore throat (34%), vomiting (26%), psychological changes (24%), fever (21%), cough (12%), and nausea (8%). A great significant complaints reduction was reported by the third post-operative day. Age, gender, admission type of the patients and GA duration were the factors that showed a significant relationship with post-operative complaints. Conclusion Post-operative morbidity was common, but mostly of mild severity and limited to the first day. Hospital staff efforts should be directed to control commonly reported postoperative complaints.</p

Repeatability of Contrast-Enhanced Ultrasound to Determine Renal Cortical Perfusion

Alterations in renal perfusion play a major role in the pathogenesis of renal diseases. Renal contrast-enhanced ultrasound (CEUS) is increasingly applied to quantify renal cortical perfusion and to assess its change over time, but comprehensive assessment of the technique’s repeatability is lacking. Ten adults attended two renal CEUS scans within 14 days. In each session, five destruction/reperfusion sequences were captured. One-phase association was performed to derive the following parameters: acoustic index (AI), mean transit time (mTT), perfusion index (PI), and wash-in rate (WiR). Intra-individual and inter-operator (image analysis) repeatability for the perfusion variables were assessed using intra-class correlation (ICC), with the agreement assessed using a Bland–Altman analysis. The 10 adults had a median (IQR) age of 39 years (30–46). Good intra-individual repeatability was found for mTT (ICC: 0.71) and PI (ICC: 0.65). Lower repeatability was found for AI (ICC: 0.50) and WiR (ICC: 0.56). The correlation between the two operators was excellent for all variables: the ICCs were 0.99 for PI, 0.98 for AI, 0.87 for mTT, and 0.83 for WiR. The Bland–Altman analysis showed that the mean biases (± SD) between the two operators were 0.03 ± 0.16 for mTT, 0.005 ± 0.09 for PI, 0.04 ± 0.19 for AI, and −0.02 ± 0.11 for WiR

Preference for Comprehensive Dental Treatment under General Anesthesia among Parents with Previous Experience: A Cross-Sectional Study

This study aims to assess whether parents of children who previously received comprehensive dental treatment under general anesthesia (GA) would prefer comprehensive dental treatment under GA over regular dental care if any of their other children required comprehensive dental treatment. In this cross-sectional study, parents of children who met the inclusion criteria were interviewed by a trained pediatric resident about parental-related factors as well as their satisfaction with their previous GA experience. Also, the factors related to the previously treated child were obtained from dental records. Statistical analysis was carried out, and the p value was set to 0.05. A total number of 306 parents were included. Although most parents, 293 (95.8%), showed satisfaction with the previous GA, 170 (58%) of the satisfied parents preferred regular care. Parents of children who were previously treated under GA for medical-related reasons (p = 0.018), fathers working in a governmental sector (p = 0.021), and families with low-average monthly income (p = 0.017) significantly preferred regular care. In conclusion, most parents were satisfied with the previous GA experience. Family income, fathers’ occupation, and medical-related factors can influence parental preference for comprehensive dental treatment under general anesthesia if any of their other children require comprehensive dental treatment
