Anesthesia was induced on both occasions with pentothal 5 mg·kg−1, fentanyl 1 μg·kg−1 and vecuronium 0.1 mg·kg−1, then maintained with nitrous oxide, oxygen and sevoflurane. Reversal of the relaxant was with atropine 0.01 mg·kg−1 and neostigmine 0.02 mg·kg−1. The patient developed inspiratory stridor immediately after extubation. His peripheral oxygen saturation (SpO2) decreased to 85%. We ventilated him with 100% oxygen and gave him IV 20 mg lidocaine and 20 mg prednisolone. Success was partial and suprasternal and intercostal recessions continued with 100% oxygen and given intravenous 20 mg lidocaine and 20 mg prednisolone. But, the success of treatment was partial and added suprasternal and intercostal indrawings. Despite giving cold humidified oxygen via facemask the patient remained tachypneic with forced respiration. At that time, the peripheral venous catheter became displaced. While attempting venous access, 20 μg of epinephrine was instilled intraorally. In a few minutes, respiration improved significantly. The final values before discharge from the recovery room without oxygen support were: pulse rate; 140 b·min−1, blood pressure; 100/60 mmHg, respiratory rate; 17 min−1, SpO2; 97% and no recessions.eninfo:eu-repo/semantics/openAccessEpinephrineLetter10.1111/j.1460-9592.2006.02081.x173297297172637512-s2.0-33846632266Q2WOS:000243792300017Q2
