Children's vomiting following posterior fossa surgery: A retrospective study.

BACKGROUND: Nausea and vomiting is a problem for children after neurosurgery and those requiring posterior fossa procedures appear to have a high incidence. This clinical observation has not been quantified nor have risk factors unique to this group of children been elucidated. METHODS: A six year retrospective chart audit at two Canadian children's hospitals was conducted. The incidence of nausea and vomiting was extracted. Hierarchical multivariable logistic regression was used to quantify risk and protective factors at 120 hours after surgery and early vs. late vomiting. RESULTS: The incidence of vomiting over a ten day postoperative period was 76.7%. Documented vomiting ranged from single events to greater than 20 over the same period. In the final multivariable model: adolescents (age 12 to <17) were less likely to vomit by 120 hours after surgery than other age groups; those who received desflurane, when compared to all other volatile anesthetics, were more likely to vomit, yet the use of ondansetron with desflurane decre kelihood. Children who had intraoperative ondansetron were more likely to vomit in the final multivariable model (perhaps because of its use, in the clinical judgment of the anesthesiologist, for children considered at risk). Children who started vomiting in the first 24 hours were more likely to be school age (groups 4 to <7 and 7 to <12) and receive desflurane. Nausea was not well documented and was therefore not analyzed. CONCLUSION: The incidence of vomiting in children after posterior fossa surgery is sufficient to consider all children requiring these procedures to be at high risk for POV. Nausea requires better assessment and documentation.

Prognostic models and risk scores: can we accurately predict postoperative nausea and vomiting in children after craniotomy?

Postoperative nausea and vomiting (PONV) is a problem for many children after craniotomy. Prognostic models and risk scores help identify who is at risk for an adverse event such as PONV to help guide clinical care. The purpose of this article is to assess whether an existing prognostic model or risk score can predict PONV in children after craniotomy. The concepts of transportability, calibration, and discrimination are presented to identify what is required to have a valid tool for clinical use. Although previous work may inform clinical practice and guide future research, existing prognostic models and risk scores do not appear to be options for predicting PONV in children undergoing craniotomy. However, until risk factors are further delineated, followed by the development and validation of prognostic models and risk scores that include children after craniotomy, clinical judgment in the context of current research may serve as a guide for clinical care in this population.

Effectiveness of teaching an early parenting approach within a community-based support service for adolescent mothers.

A single blind, pre-test, post-test design was used to test the effectiveness of the Keys to Caregiving Program in enhancing adolescent mother-infant interactions. Participants were sequentially allocated to groups in order of referral. The outcome was the enhancement of maternal and infant behaviors that exhibited mutual responsiveness as measured by the Nursing Child Assessment Teaching Scale. Issues with recruitment and collaboration with the community agencies made achieving a desirable sample size difficult. Pre-tests and post-tests were completed for 13 participants. While the sample size was insufficient to confidently establish whether or not the Keys to Caregiving produced a between groups treatment effect, mothers within the treatment group evidenced significantly greater contingent responsiveness over time than those within the control group.

Home visitation practice: models, documentation, and evaluation.

This article presents an evaluation of an in-home support program for at-risk mothers and their children. The program was multidisciplinary and was focused on development of parenting capacity and child-development competencies. The authors examine issues and problems that resulted from the blending of two models of practice-stabilization/crisis intervention and early intervention/health promotion-and describe the outcome-based evaluation that was used to assess initial and ongoing child development, parent-child interaction, family environment, and social support. When documentation and evaluation of practice and its effect on outcomes proved a considerable challenge, the authors developed a classification system to describe practice in three areas: situations addressed, interventions used, and referrals made. The article describes challenges surrounding program development, implementation, and evaluation.
