Propofol-remifentanil intravenous anesthesia and spontaneous ventilation for airway foreign body removal in children with preoperative respiratory impairment.
Summary of "Propofol-remifentanil intravenous anesthesia and spontaneous ventilation for airway foreign body removal in children with preoperative respiratory impairment."
Purpose:â€‚ To investigate the efficacy and safety of propofol-remifentanil total intravenous anesthesia (TIVA) and spontaneous ventilation for foreign body (FB) removal in pediatric patients with preoperative respiratory impairment. Methods:â€‚ We carried out a prospective observational clinical study of FB removal using a rigid bronchoscope under propofol-remifentanil TIVA and spontaneous ventilation in 65 pediatric patients who presented with preoperative respiratory impairment. Heart rate, blood pressure, pulse oxygen saturation (SpO(2) ), respiratory rate, endtidal CO(2) (ETCO(2) )(,) induction time, and remifentanil rate were recorded. Adverse events, the intervention for these events, and the duration of postoperative care were also of interest. Results:â€‚ Sixty children completed the study. The mean induction time was 12.3â€ƒmin. During the procedure, the maximum remifentanil rate was 0.14â€ƒÎ¼gÂ·kg(-1) Â·min(-1) . Light breath holding occurred in 16 (26.7%) patients. No severe breath holding or body movements were observed. An SpO(2) below 90% occurred in 10 (16.7%) cases. No progressive desaturation was observed. The mean ETCO(2) at the end of the procedures was 7.91 KPa and returned to normal 5â€ƒmin after the procedure. In the postanesthesia care unit (PACU), no hypoxemia was observed and the mean recovery time was 23.4â€ƒmin. No laryngospasm, pneumothorax, or arrhythmias were observed. Conclusion:â€‚ Propofol-remifentanil TIVA and spontaneous ventilation are effective and safe techniques to manage anesthesia during airway FB removal in children with preoperative respiratory impairment.

Medical and Biotech [MESH] Definitions
A type of oropharyngeal airway that provides an alternative to endotracheal intubation and standard mask anesthesia in certain patients. It is introduced into the hypopharynx to form a seal around the larynx thus permitting spontaneous or positive pressure ventilation without penetration of the larynx or esophagus. It is used in place of a facemask in routine anesthesia. The advantages over standard mask anesthesia are better airway control, minimal anesthetic gas leakage, a secure airway during patient transport to the recovery area, and minimal postoperative problems.
An intravenous anesthetic agent which has the advantage of a very rapid onset after infusion or bolus injection plus a very short recovery period of a couple of minutes. (From Smith and Reynard, Textbook of Pharmacology, 1992, 1st ed, p206). Propofol has been used as ANTICONVULSANTS and ANTIEMETICS.
Evaluation, planning, and use of a range of procedures and airway devices for the maintenance or restoration of a patient's ventilation.
An intravenous anesthetic that has been used for rapid induction of anesthesia and for maintenance of anesthesia of short duration. (From Martindale, The Extra Pharmacopoeia, 30th ed, p918)
Techniques for effecting the transition of the respiratory-failure patient from mechanical ventilation to spontaneous ventilation, while meeting the criteria that tidal volume be above a given threshold (greater than 5 ml/kg), respiratory frequency be below a given count (less than 30 breaths/min), and oxygen partial pressure be above a given threshold (PaO2 greater than 50mm Hg). Weaning studies focus on finding methods to monitor and predict the outcome of mechanical ventilator weaning as well as finding ventilatory support techniques which will facilitate successful weaning. Present methods include intermittent mandatory ventilation, intermittent positive pressure ventilation, and mandatory minute volume ventilation.
