Obstructive sleep apnoea syndrome in children and anaesthesia

Predictors of perioperative respiratory adverse events among children with upper respiratory tract infection undergoing pediatric ambulatory ilioinguinal surgery: a prospective observational research

Objectives

Anesthesia for children with an upper respiratory tract infection (URI) has an increased risk of perioperative respiratory adverse events (PRAEs) that may be predicted according to the COLDS score. The aims of this study were to evaluate the validity of the COLDS score in children undergoing ilioinguinal ambulatory surgery with mild to moderate URI and to investigate new predictors of PRAEs.

Methods

This was a prospective observational study including children aged 1–5 years with mild to moderate symptoms of URI who were proposed for ambulatory ilioinguinal surgery. The anesthesia protocol was standardized. Patients were divided into two groups according to the incidence of PRAEs. Multivariate logistic regression was performed to assess predictors for PRAEs.

Results

In this observational study, 216 children were included. The incidence of PRAEs was 21%. Predictors of PRAEs were respiratory comorbidities (adjusted OR (aOR)=6.3, 95% CI 1.19 to 33.2; p=0.003), patients postponed before 15 days (aOR=4.3, 95% CI 0.83 to 22.4; p=0.029), passive smoking (aOR=5.31, 95% CI 2.07 to 13.6; p=0.001), and COLDS score of >10 (aOR=3.7, 95% CI 0.2 to 53.4; p=0.036).

Conclusions

Even in ambulatory surgery, the COLDS score was effective in predicting the risks of PRAEs. Passive smoking and previous comorbidities were the main predictors of PRAEs in our population. It seems that children with severe URI should be postponed to receive surgery for more than 15 days.

The impact of emergence delirium on hospital length of stay for children who underwent tonsillectomy/adenotonsillectomy: an observational retrospective study

BACKGROUND

Emergence Delirium (ED) is a combination of disturbance of perception and psychomotor agitation that is common in pediatric patients after general anesthesia, especially at preschool age. Since the effect of ED on the length of stay has been studied in adults but infrequently in children, the aim of this study was to investigate the relationship between ED and length of stay in this population.

METHODS

A single center, retrospective, observational study was carried out in children who underwent tonsillectomy or adenotonsillectomy. The Pediatric Anesthesia Emergence Delirium (PAED) scale was used to assess ED. In addition to the time to hospital discharge (time frame 24 hours), drugs used, comorbidities, early postoperative complications, and pain were investigated if potentially associated with the complication.

RESULTS

Four hundred sixteen children aged from 1.5 to 10 years (183 female, 233 male) were included. ED occurred in 25.5% of patients (n = 106). Patients were divided into the ED group and the No-ED group. The discharge time was similar in both groups. No significant differences were observed in the frequency of postoperative complications. The use of fentanyl or dexmedetomidine did not affect ED occurrence. The frequency of pain was greater in the ED group, both in the recovery room and in the ward (p = 0.01).

CONCLUSIONS

The occurrence of ED in children after tonsillectomy/adenotonsillectomy did not extend the length of stay.

Incidence of children at risk for obstructive sleep apnea undergoing common day surgery procedures

OBJECTIVE

The purpose of this study was to evaluate the prevalence of sleep-related breathing disorders (SRBD) in children undergoing elective day surgery procedures.

METHODS

A validated Pediatric Sleep Questionnaire (PSQ) was distributed to the parents of children aged 2months to 18 years who met inclusion criteria and were undergoing urologic, otolaryngologic, and general surgical day surgery procedures a 3-month period of time. The prevalence of children at risk for pediatric SRBD was determined from PSQ results.

RESULTS

From a total of 288 PSQ Questionnaires, 9.1% of urology, 11.1% of general surgery, and 51.9% of otolaryngology patients admitted to day surgery were found to be at risk for sleep disordered breathing. The median PSQ score for the children at risk was 9.2 for urological surgeries, 10.9 for general surgery, and 11.3 for otolaryngological procedures.

CONCLUSIONS

There is an increased prevalence of children at risk of SRBD awaiting common day surgery procedures than previously expected based on existing literature. Patients undergoing otolaryngological procedures were at greater risk of sleep-related breathing disorders when compared with patients undergoing urological or general surgical procedures. There may be a role for screening of pediatric patients with a PSQ prior to day-surgery.

Management of severe sleep apnea secondary to juvenile arthritis with temporomandibular joint replacement and mandibular advancement

Variations affecting the growth centers can severely affect the normal formation and subsequent function of vital musculoskeletal structures. We report a case of bilateral condylar atrophy with a history of juvenile arthritis (JA) resulting in progressive obstructive sleep apnea (OSA) in adulthood. In addition to this, the case report emphasizes the role of temporomandibular joint replacement and advancement of the mandible to correct progressive OSA secondary to idiopathic JA. Computed tomography revealed micrognathia, condylar hypoplasia, and decreased pharyngeal airway space. The resultant increase in the retrolingual-pharyngeal airway space following the surgery, helped to completely resolve the presenting symptoms. It is hoped that the described technique could be used in similar cases with a predictable outcome.
