Family-centered preparation for surgery improves perioperative outcomes in children: a randomized controlled trial.

BACKGROUND: Children and parents experience significant anxiety and distress during the preoperative period. Currently available interventions are having limited efficacy. Based on an integration of the literature in both the anesthesia and psychological milieus, the authors developed a behaviorally oriented perioperative preparation program for children undergoing surgery that targets the family as a whole. METHODS: Children and their parents (n = 408) were randomly assigned to one of four groups: (1) control: received standard of care; (2) parental presence: received standard parental presence during induction of anesthesia; (3) ADVANCE: received family-centered behavioral preparation; and (4) oral midazolam. The authors assessed the effect of group assignment on preoperative anxiety levels and postoperative outcomes such as analgesic consumption and emergence delirium. RESULTS: Parents and children in the ADVANCE group exhibited significantly lower anxiety in the holding area as compared with all three other groups (34.4+/-16 vs. 39.7+/-15; P=0.007) and were less anxious during induction of anesthesia as compared with the control and parental presence groups (44.9+/-22 vs. 51.6+/-25 and 53.6+/-25, respectively; P=0.006). Anxiety and compliance during induction of anesthesia was similar for children in both the ADVANCE and midazolam groups (44.9+/-22 vs. 42.9+/-24; P=0.904). Children in the ADVANCE group exhibited a lower incidence of emergence delirium after surgery (P=0.038), required significantly less analgesia in the recovery room (P=0.016), and were discharged from the recovery room earlier (P=0.04) as compared with children in the three other groups. CONCLUSION: The family-centered preoperative ADVANCE preparation program is effective in the reduction of preoperative anxiety and improvement in postoperative outcomes.

Pediatric procedural pain.

This article reviews the various settings in which infants, children, and adolescents experience pain during acute medical procedures and issues related to referral of children to pain management teams. In addition, self-report, reports by others, physiological monitoring, and direct observation methods of assessment of pain and related constructs are discussed and recommendations are provided. Pharmacological, other medical approaches, and empirically supported cognitive behavioral interventions are reviewed. Salient features of the interventions are discussed, and recommendations are made for necessary components of effective treatment interventions.

Behavioral interactions in the perioperative environment: a new conceptual framework and the development of the perioperative child-adult medical procedure interaction scale.

BACKGROUND: The authors suggest that research in the area of parental presence during induction of anesthesia should shift to emphasize what parents actually do during induction, rather than focusing simply on their presence. As a first step, the authors aimed to develop a behavioral coding system that would measure child and adult interactions in the perioperative environment. METHODS: The authors enrolled 45 parents and children (aged 2-12 yr) undergoing elective surgery and general anesthesia. A multidisciplinary team examined videotapes and transcriptions of interactions between children, parents, and medical personnel in the holding room and operating room. The team used an existing scale, the Child-Adult Medical Procedure Interaction Scale, as the prototype for the development of a new perioperative behavioral coding system. The research team conducted extensive revisions to the original scale and added multiple codes to the original scale, including nonverbal codes. Interrater reliability was assessed using weighted kappa statistics. Construct validity was also examined. RESULTS: The final Perioperative Child-Adult Medical Procedure Interaction Scale contains 40 codes in four domains. Analyses showed excellent reliability overall for verbal and nonverbal codes. Kappa values averaged 0.87 for verbal codes characterizing adult vocalizations, 0.92 for verbal codes characterizing child vocalizations, and 0.88 for nonverbal codes. Construct validity was demonstrated by finding the hypothesized associations between certain scale codes and children's anxiety (P = 0.0001). CONCLUSION: Showing excellent reliability, the Perioperative Child-Adult Medical Procedure Interaction Scale is an appropriate tool for assessing child-adult behavioral interaction during the perioperative period. When sequential analyses are conducted and target behaviors are identified, empirically based parent preparation programs can be developed.

Parent and child psychological factors in pediatric syncope and other somatic symptoms.

The authors examined associations among parental and child adjustment, child syncope, somatic, and school problems. Participants were children (N = 56) ages 7-18 years with syncope. Measures included syncope severity, parental distress, and children's internalizing symptoms. For children diagnosed negative for neurocardiogenic syncope (NCS), their fathers' and their own psychological symptoms were positively associated with the severity of syncope, whereas their mothers' functioning was negatively associated with the severity of syncope. Also, for the negative NCS group, fathers' psychological functioning was associated with children's nonsyncope somatic complaints but not with their school problems. For the positive NCS group, few significant father-child associations were found, but several significant positive associations were revealed between mothers' psychological symptoms and their children's syncope as well as somatic and school problems.

The role of ethnic identity and self-construal in coping among African American and Caucasian American seventh graders: an exploratory analysis of within-group variance.

Much coping research has been conducted comparing members of different ethnic groups using discrete racial classifications. However, the past two decades have seen the construct of ethnicity evolve into a complex variable that must be assessed in a more comprehensive way. This study explored how ethnicity, a discrete variable, and the continuous variables of a person's ethnic identity and self-construal contribute to the use of particular coping strategies across various situations. One hundred twelve seventh graders (67 African Americans and 45 Caucasian Americans) from three suburban middle schools completed questionnaires assessing ethnic identity, self-construal, and coping strategies for medical, test, and social criticism stressors. Results supported the hypothesis that ethnicity as a discrete variable is not associated with coping, but that ethnic identity and self-construal are. It was also found that high scores on the ethnic identity and self-construal scales were indicative of more positive psychological adjustment. Implications for future research and methodological considerations are discussed.

The relationship between children's coping styles and psychological interventions for cold pressor pain.

This study examined the hypothesis that matching pain management interventions to children's preferred coping methods would increase pain tolerance and decrease self-reported pain during the cold pressor pain paradigm. Children aged 8-10 years were classified as 'attenders' (focusing on the stimulus) or 'distractors' (focusing away from the stimulus) based upon their spontaneous coping responses during a baseline exposure to the cold pressor. Children were then randomly assigned to 1 of 3 intervention conditions (sensory focusing, imagery, or no intervention) and completed the cold pressor procedure again 2 weeks later. A significant interaction was found between coping style and intervention. Children who were classified as distractors demonstrated greater tolerance when taught to use imagery techniques (a 'matched' intervention). Although pain ratings tended to be lower for distractors using imagery, the significant interaction resulted from an increase in ratings for the distractors using sensory focusing (i.e., a 'mismatched' intervention). Results suggest that, for distractors, interventions that are consistent with natural coping methods are most effective in enhancing abilities to cope with pain, while a mismatched intervention reduces coping abilities. The findings also suggest further study regarding how to provide effective pain intervention with attenders, since neither intervention enhanced coping in this group.
