Monochromic light reduces emergence delirium in children undergoing adenotonsillectomy; a double-blind randomized observational study.

ABSTRACT:

Background

Emergence delirium (ED) is common in pediatric anesthesia. This dissociative state in which the patient is confused from their surroundings and flailing can be self-injurious and traumatic for parents. Treatment is by administration of sedatives which can prolong recovery. The aim of this study was to determine if exposure to monochromatic blue light (MBL) in the immediate phase of recovery could reduce the overall incidence of emergence delirium in children following general inhalational anesthesia.

Methods

This double blinded randomized controlled study included patients ages 2-6 undergoing adenotonsillectomy. Postoperatively, 104 patients were randomization (52 in each group) for exposure to sham blue or MBL during the first phase (initial 30 min) of recovery. The primary outcome was the incidence of emergence delirium during the first phase. We also examined Pediatric Anesthesia Emergence Delirium (PAED) scores throughout the first phase.

Results

Emergence Delirium was reported in 5.9% of MBL patients versus 33.3% in the sham group, p = 0.001. Using logistic regression adjusting for age, weight, gender, ASA classification and PAED scores provided an adjusted relative risk ratio of 0.18; 95% CI (0.06, 0.54); p = 0.001 for patients in the MBL group. 23.5% of MBL patients versus 52.9% of sham patients had either ED or PAED scores of 12 or more throughout the first phase of recovery, p = 0.002. This produced an adjusted relative risk of 0.46, 95% CI (0.29, 0.75), p = 0.001.

Conclusions

Monochromatic blue light represents a non-pharmacologic method to reduce the incidence of emergence delirium and PAED scores in children.

Project description:Objective: There is no universal agreement on optimal pharmacological regimens for pain management during surgeries. The aim of this study to compare the postoperative analgesic effects of nalbuphine with fentanyl in children undergoing adenotonsillectomy. Design, Setting, Participants: We conducted a prospective, randomized, double-blind, non-inferiority and multicenter trial in 311 patients admitted to four different medical facilities in China from October 2017 to November 2018. Main Outcome Measure: The primary outcome was postoperative pain score. The secondary outcomes were as follows: the numbers of patients who developed moderate or severe pain (FLACC ≥4 points); time to first rescue analgesic top up and the actual number of rescue pain medicine given in pain control in post-anesthesia care unit (PACU), and additional analgesics requirement (received ≥2 rescue analgesics or/and other analgesics except study medications administered in PACU and ward); emergence and extubation time; Waking up time; time of PACU stay, and other side effects (desaturation, nausea/vomiting etc.). Results: A total of 356 children were screened and 322 patients were randomized. The mean age was 5.8 (5.5, 6.1) in the nalbuphine group and 5.6 (5.3, 5.8) in the fentanyl group (p = 0.2132). FLACC score of nalbuphine group was lower than that of fentanyl group upon patients' arrival at PACU (p < 0.05). The time to first required rescue dose of pain drug for nalbuphine group was longer than for the fentanyl group (2.5 vs 1.2 h, p < 0.0001). Only one patient (0.6%) in nalbuphine group presented a slow respiratory rate (RR) at 9/min while 29 patients (18.5%) in fentanyl group developed slow RR ≤10/min in PACU. Meanwhile, SpO2 was lower in the fentanyl group at 10 min after patients' arrival in PACU (p < 0.05). The other profiles observed from these two drug groups were similar. Conclusion: Nalbuphine provided better pain relief with minimal respiration depression than fentanyl in children undergoing Adenotonsillectomy.

Project description:Background Emergence delirium (ED) is common in pediatric patients undergoing general anesthesia with sevoflurane. Preoperative sleep quality is associated with the risk factors for ED. However, research on the relationship between sleep quality and ED is limited. We aimed to investigate the relationship between ED and preoperative sleep quality in pediatric patients undergoing strabismus surgery. Methods This clinical trial included pediatric patients aged 4–12 years who underwent elective strabismus surgery. The patients and their parents were questioned about the patients’ preoperative sleep quality using the Pittsburgh Sleep Quality Index (PSQI) questionnaire. For anesthesia induction, thiopental (5 mg/kg) and rocuronium (0.6 mg/kg) were used, and anesthesia was maintained with sevoflurane (minimum alveolar concentration, 1–1.5). After administration of a reversal drug, extubation was performed, and the patients were transferred to a post-anesthesia recovery unit. At 10 min after extubation, the degree of ED was measured using the pediatric anesthesia emergence delirium (PAED) and Watcha scale scores. Results Of the 62 enrolled patients, three pediatric patients were excluded. The overall incidence of ED was 22%. A total of 59 patients were divided into the two groups. The ED group and the non-ED group comprised 13 and 46 patients. Age, height and weight were significantly lower in the ED group than in the non-ED group. Preoperative PSQI and Watcha scale score were significantly higher in the ED group than in the non-ED group. Multivariate analysis showed that age (adjusted OR [95% CI]: 0.490 [0.290–0.828], p = 0.008) and preoperative PSQI score (adjusted OR [95% CI]: 2.149[1.224–3.771], p = 0.008) was associated with ED. In sub-group analysis, PAED scale and Watcha scale scores showed a moderate correlation with preoperative sleep quality in preschool-age patients. Conclusion In conclusion, the incidence of ED tended to be higher in younger age and poorer preoperative sleep quality in pediatric patients. In particular, the poorer sleep quality score was associated with higher incidence of ED in the preschool-age. Large-scale clinical studies and long-term follow-up studies on ED and sleep quality are required.

Project description:BACKGROUND:Adenotonsillectomy is the most frequently performed operation in children worldwide. For decades, prophylactic antibiotics have been prescribed to limit postoperative complications. The effect of this antibiotic use has been refuted in a Cochrane Review. However, all reviewed studies were carried out in developed countries. In Tanzania, like many other developing countries with limited resources and a high burden of infectious diseases, postoperative antibiotic prescription is still very common to decrease the supposed higher postoperative morbidity. However, as a consequence of this widespread use of postoperative antibiotics, cross-resistance and risk of allergic side effects rise. Well-designed randomized controlled trials are needed to limit unnecessary antibiotic prescription and secondary antibiotic resistance. AIM:The aim of this study is to analyse the prophylactic role of postoperative antibiotics on morbidity following adenotonsillectomy in children in Tanzania. DESIGN:The double-blinded, randomized, placebo-controlled trial was set in northern Tanzania. Participating centres are the Department of Otolaryngology at Kilimanjaro Christian Medical Centre in Moshi and the Department of Paediatric Surgery at the Arusha Lutheran Medical Centre in Arusha. METHODS:Around 270 children aged 2-14?years, all scheduled for elective (adeno)tonsillectomy, will be included and assigned to receive either a standard regimen of 5?days of antibiotic prophylaxis or placebo after surgery. The primary outcomes are postoperative haemorrhage, fever and pain. Secondary outcomes are the time until normal diet is resumed, the time until normal activities are resumed and the occurrence of adverse events and microbial recolonization of the tonsillar beds. DISCUSSION:This study will enhance an increase of proper antimicrobial prescription in Tanzanian institutions as well as other resource-limited countries where prescription of antibiotics is still very common. In addition, it might augment current knowledge about surface and core tonsillar micro-organisms and sensitivity patterns.
