Foreign body aspiration in adults and in children: advantages and consequences of a dedicated protocol in our 30-year experience.

BACKGROUND: Foreign body (FB) inhalation is a potentially life-threatening emergency also in clinically stable patients as the situation could worsen at any moment. There is varying opinion regarding the urgency for removal of inhaled FBs, and there are no guidelines in the literature. The aim of our study was to present our experience with FB aspiration in children and adults from 1993, when we introduced our Thoracic Endoscopy Service with the availability "on call" of a bronchologist 24 hours a day, 7 days a week, defining a dedicated protocol together with our anaesthesiologists for prompt intervention in this situation. METHODS: We consulted our database and examined the records of all patients undergoing bronchoscopy for suspected FB aspiration from 1993 onwards; our previous experience of 11 children and 14 adults with FBs from 1981 to 1992 was also included to compare the results obtained. RESULTS: In this period, we removed 159 FBs (in 70 children and 89 adults) and performed 23 negative bronchoscopies in children and 6 in adults for suspected aspiration. All FBs were removed successfully. We were able to intervene immediately also in critical situations: in 60/70 children within 24 hours of admission to hospital, in 44 of these 60 on the actual day of admission, thus avoiding a potentially dangerous delay between aspiration and removal. We had no complications, and no patients needed surgery. CONCLUSIONS: We conclude that an efficient organization involving a dedicated protocol of intervention, trained staff available 24 hours a day, 7 days a week, appropriate setting, and the right instrumentation enabled us to tackle this important emergency.

Emergence agitation in preschool children: double-blind, randomized, controlled trial comparing sevoflurane and isoflurane anesthesia.

BACKGROUND: This randomized, double-blind controlled trial was conducted to determine whether the association of sevoflurane for induction and isoflurane for anesthesia maintenance resulted in a lower incidence of postoperative agitation compared with sevoflurane as single agent. METHODS: After Institute Ethics Committee's approval and parental written informed consent, 128 unpremedicated children (1-6 years), ASA I-II, scheduled for elective subumbilical surgery were enrolled. After induction with 8% sevoflurane, patients were randomly allocated to receive sevoflurane or isoflurane 1-1.5 MAC as maintenance agent. The primary endpoint of the study was the incidence of postoperative agitation defined as a screaming and crying child and/or a child that required physical restraint during emergence. RESULTS: Eighteen children were excluded because they received sedatives, analgesia or anesthesia or because of ineffective regional analgesia before randomization. Fifty-four patients receiving sevoflurane and 56 receiving isoflurane completed the study. Twenty-eight children (95% CI 38-66%) in the sevoflurane group presented with postoperative agitation compared with 18 (95% CI 20-46%) patients receiving isoflurane (P = 0.028). Fifteen minutes after awakening, 11/54 children receiving sevoflurane were agitated compared with 4/56 receiving isoflurane (P = 0.03). Thereafter, there was a gradual reduction in the incidence of postoperative agitation over time. CONCLUSIONS: The association of sevoflurane for induction and isoflurane for maintenance produced significant less postoperative agitation in preschool children receiving regional anesthesia during subumbilical surgery compared with sevoflurane for induction and maintenance.
