Insights
Rapid sequence intubation (RSI) in children is generally safe, with a 1.7% rate of difficult intubation and 3.6% experiencing transient desaturation. Severe hypoxemia was more common in children under 20 kg, but no long-term complications occurred.
Area of Science:
- Pediatric Anesthesiology
- Emergency Medicine
- Critical Care
Background:
- Rapid sequence intubation (RSI) is increasingly used outside the operating room by non-anesthesiologists.
- There is a lack of established benchmarks for intubation success and complication rates in pediatric RSI.
- This study addresses the need for data on pediatric RSI outcomes.
Purpose of the Study:
- To determine the incidence of complications during pediatric RSI.
- To establish a benchmark for RSI in children for other institutions and non-anesthesiologists.
- To analyze factors influencing complications in pediatric RSI.
Main Methods:
- Retrospective cohort analysis of 1070 children aged 3-12 years undergoing RSI.
- Data collected from 2001 to 2006 in a tertiary care children's hospital.
- Complications analyzed included difficult intubation, hypoxemia, hypotension, and bradycardia.
Main Results:
- Difficult intubation occurred in 1.7% of cases, with all patients eventually intubated.
- Transient oxyhemoglobin desaturation (SpO2 80-89% or <80%) occurred in 3.6% of patients.
- Severe hypoxemia was more frequent in children weighing less than 20 kg (P < 0.001).
Conclusions:
- Pediatric RSI in this cohort demonstrated a low incidence of difficult intubation and transient desaturation.
- Children under 20 kg represent a higher risk group for severe hypoxemia during RSI.
- No instances of failed intubation or long-term complications were reported, supporting RSI's safety in pediatric populations.
Objectives:
Determine incidence of complications such as difficult or failed intubation, hypoxemia, hypotension, and bradycardia in children undergoing rapid sequence intubation (RSI) in a pediatric anesthesia department in a tertiary care children's hospital.
Aim:
To establish a benchmark to be used by other institutions and nonanesthesiologists performing RSI in children.
Background:
RSI is being increasingly performed in the nonoperating room setting by nonanesthesiologists. No published studies exist to establish a benchmark of intubation success or failure and complications in this patient population.
Methods/Materials:
Retrospective cohort analysis of children aged 3-12 undergoing RSI from 2001 to 2006.
Results:
One thousand seventy children underwent RSI from 2001 to 2006. Twenty (1.9%) developed moderate hypoxemia (SpO(2) 80-89%), 18 (1.7%) demonstrated severe hypoxemia (SpO(2) < 80%), 5 (0.5%) developed bradycardia (heart rate <60), and 8 (0.8%) developed hypotension (systolic blood pressure <70 mmHg). One patient had emesis of gastric contents but no evidence of pulmonary aspiration or hypoxemia. Eighteen (1.7%) children were noted to be difficult to intubate and required more than one intubation attempt. All were eventually intubated without significant complications. Patients between 10 and 19 kg had a higher incidence of severe hypoxemia when compared with older children (P < 0.001). There was no association between choice of muscle relaxant and any complication.
Conclusions:
In our cohort of 1070 children who underwent RSI, difficult intubation was encountered in 1.7% and transient oxyhemoglobin desaturation occurred in 3.6%. Severe hypoxemia was more likely in children <20 kg. There were no children who could not be intubated, and there were no long-term or permanent complications.
