Official Title: Multi-Center Study on the Incidence of Intra-operative Awareness and Recall in the Pediatric Population Undergoing General Anesthesia: CARE--Childhood Awareness and Recall

Brief Summary:

The purpose of this study is to describe the incidence of recall or awareness under anesthesia in children aged 5-15 by collecting anesthetic and post-operative follow-up data relating to intra-operative recall during general anesthesia.

The hypothesis is that the implementation of routine awareness follow-up evaluation in children undergoing general anesthesia will identify that the incidence of intra-operative awareness in children is equal to or greater than in adults.


Detailed Summary:

Awareness, or the unwanted recall of intra-operative events occurring during general anesthesia, is a potentially avoidable anesthetic complication that poses the risk for psychological sequelae. While the reported incidence is 0.1-0.2% in adults, this translates to > 20,000 cases of awareness occurring in adults annually in the United States (Ekman, 2004; Myles, 2000; Sandin, 2000; Sebel, 2004; Myles, 2004). Patients who experience recall may subsequently exhibit post-traumatic stress and psychological symptoms (Sebel, 2004; Myles, 2004; Moerman, 1993; Lennmarken, 2002). Furthermore; studies have shown that up to 54% of adult patients worry about the possibility of awareness during surgery (Klafta, 1996). Subsequent to the recent studies on unintended intraoperative awareness and published data on the impact of Bispectral Index in preventing and detecting anesthesia awareness, the Joint Commission on Accreditation of Healthcare Organizations has classified intraoperative awareness as a sentinel event (2004).

Limited data are available regarding the incidence and consequences of awareness in children. Studies which are available have identified a significantly higher incidence of intraoperative recall in children than has been shown in adults. McKie reported an incidence of 5% factual recall in 202 patients aged 7-14 years in 1973 (1973). The incidence of dreaming was reported as 11%. Hobbs, in 1988, reported a 19% incidence of dreaming and no awareness in 120 pediatric patients who received the "Liverpool anesthetic technique" (N20, O2, relaxant). Ranta reported 0.4% awareness in 4800 patients aged 12 years or older, with the youngest patient demonstrating undisputed awareness at 20 years of age (1998). More recently, Lopez et. al., found an 8% incidence of awareness in children 6-16 years of age, with a significant relationship between multiple attempts to
