Why the study?
Does age influence the incidence and severity of early postoperative hypoxemia in healthy patients undergoing elective plastic surgery?
Does age influence the incidence and severity of early postoperative hypoxemia in healthy patients undergoing elective plastic surgery?
Younger age, particularly infancy and early childhood, is associated with a higher risk of early postoperative hypoxemia following elective plastic surgery in otherwise healthy patients.
May warrant closer SpO2 monitoring in younger postoperative patients; leaves open need for prospective age-specific trials.
To determine the influence of age on postoperative hypoxemia, we studied postoperative hypoxemia in 1152 patients, from infants to adults, ASA physical status I, undergoing elective plastic surgery.Subjects were divided into four groups on the basis of age: Group 1, infants aged 1 yr or less (n = 108); Group 2, children aged 1-3 yr (n = 240); Group 3, children aged 3-14 yr (n = 482); and Group 4, adults aged 14-58 yr (n = 322). Arterial oxygen saturation (SpO2) levels were recorded while patients were breathing room air in the postanesthesia recovery room shortly after arrival (0 min), and 5, 10, 15, 20, 30, 40, 50, 60, 120, and 180 min thereafter. Younger patients showed lower SpO2 levels and a higher incidence of hypoxemia during the early postoperative period. The incidences of hypoxemia (SpO2 = 86%-90%) and severe hypoxemia (SpO2
