Insights
Tracheal extubation impairs oxygenation in children. Lung inflation with 100% oxygen before extubation, especially in young children, improves arterial oxygen saturation (SpO2) and reduces the need for supplemental oxygen.
Area of Science:
- Anesthesiology
- Pediatric Critical Care
Background:
- Tracheal extubation is a critical step in pediatric anesthesia.
- Maintaining adequate arterial oxygen saturation (SpO2) post-extubation is vital for patient safety.
Purpose of the Study:
- To investigate the impact of two tracheal extubation techniques on SpO2 in children.
- To compare the efficacy of lung inflation versus suction during extubation.
Main Methods:
- Prospective study of 120 pediatric patients (ASA I-III).
- Randomized groups: lung inflation with 100% oxygen before extubation (Group I) vs. suction during extubation (Group S).
- Monitoring of SpO2 for 5 minutes post-extubation, with supplemental oxygen if SpO2 < 92%.
Main Results:
- Group S required more frequent oxygen administration (65.6% vs. 45.8%, P=0.04).
- Group S experienced a three-fold shorter time to SpO2 decrease to 92% (25s vs. 85s, P=0.0001).
- Negative effects were more pronounced in children under 4 years old.
Conclusions:
- Tracheal extubation significantly impairs oxygenation in children.
- Suction during extubation exacerbates oxygenation impairment, particularly in younger children.
- Pre-extubation lung inflation with 100% oxygen is recommended to maintain SpO2.
Abstract:
We studied prospectively the effects of the technique of tracheal extubation on arterial haemoglobin oxygen saturation (SpO2) in 120 ASA I-III children, mean age 5.3 (range 0.25-16.9) yr. At completion of surgery, tracheal extubation was performed when spontaneous ventilation had resumed, children were fully awake and SpO2 was 99-100%. Children were allocated randomly to receive a single lung inflation manoeuvre with 100% oxygen before tracheal extubation (group I; n = 59) or to have the tracheal tube removed while applying suction through the tube (group S; n = 61). SpO2 was monitored during the first 5 min after tracheal extubation in the operating room. Supplementary oxygen was given if SpO2 decreased to less than 92%. The time between tracheal extubation and decrease in SpO2 to 92% (T92) was recorded. Children in group S required oxygen administration more frequently after tracheal extubation than those in group I (65.6% vs 45.8%; P = 0.04), and had a three-fold shortening of T92 (mean 25 (SD 19) s vs 85 (63) s; P = 0.0001). These effects were more pronounced in children less than 4 yr of age compared with older children. We conclude that tracheal extubation greatly impaired oxygenation and therefore administration of oxygen was appropriate. This impairment was more marked when suction was used, and in young children. Lung inflation with 100% oxygen before removal of the tracheal tube is advised before routine tracheal extubation in children.
