Summary Purpose To evaluate the efficacy and safety of a spontaneous ventilation anesthesia technique with insufflation of oxygen and volatile agent through a double‐lumen central venous catheter ( DLCVC ) in pediatric patients undergoing suspension laryngoscopic surgery for laryngeal papillomatosis. Methods Thirty‐six pediatric patients with laryngeal papillomatosis undergoing suspension laryngoscopic surgery were anesthetized with oxygen and volatile anesthetic insufflation while spontaneously breathing. Anesthesia was induced by inhalation of 8% sevoflurane in oxygen by mask. Atropine, dexamethasone, lidocaine, and midazolam were administered intravenously. The tip of a 7Fr DLCVC was inserted below the glottis after placement of the laryngoscope and establishing suspension. Anesthesia was maintained with insufflation of 4–6% sevoflurane and oxygen with a total fresh gas flow of 6 l·min −1 through the 14G (larger lumen) of the DLCVC . Endtidal carbon dioxide tension (PetCO 2 ) was monitored using the other lumen of the DLCVC , which was connected to the CO 2 sampling line. Duration of the procedure as well as total anesthesia time was recorded. Electrocardiography ( ECG ), heart rate ( HR ), mean arterial pressure ( MAP ), oxygen saturation (SpO 2 ), and PetCO 2 were also monitored. Arterial blood was sampled for blood gas analysis including pH, PaO 2 , PaCO 2 , and actual base excess ( ABE ). Complications, including intraoperative patient movement, hypoxemia (SpO 2 < 95% during oxygen insufflation), nausea, vomiting, bronchospasm, and arrhythmias, were recorded. Results There was a significant increase in PetCO 2 and PaCO 2 ( P values <0.05) as well as a decrease in ABE , pH, and PaO 2 ( P values <0.05) in samples collected before and after surgery. MAP , HR , and SpO 2 after surgery were not significantly different from after induction values ( P values >0.05). During surgery, SpO 2 < 95% in three cases and body movements in three cases were observed. No patient had any other of the complications previously described. Furthermore, no postsurgical endotracheal intubation was needed in any patient. Conclusion After establishing an adequate depth of anesthesia, a spontaneous ventilation anesthesia technique with insufflation of oxygen and volatile agent through a DLCVC is feasible in pediatric patients undergoing suspension laryngoscopic surgery for laryngeal papillomatosis.
