Pathways by which Maternal Factors are Associated With Youth Spina Bifida-Related Responsibility

OBJECTIVE

Achieving condition-related autonomy is an important developmental milestone for youth with spina bifida (SB). However, the transfer of condition-related responsibility to these youth can be delayed due to parent factors. This study aimed to investigate two potential pathways by which maternal factors may be associated with condition-related responsibility among youth with SB: (a) Maternal adjustment → perception of child vulnerability (PPCV) → youth condition-related responsibility; and (b) Maternal PPCV → overprotection → youth condition-related responsibility.

METHODS

Participating youth with SB (N = 140; Mage=11.4 years, range = 8-15 years) were recruited as part of a longitudinal study; data from three time points (each spaced 2 years apart) from the larger study were used. Mothers reported on personal adjustment factors, PPCV, and overprotection. An observational measure of overprotection was also included. Mothers, fathers, and youth with SB reported on youths' degree of responsibility for condition-related tasks. Analyses included age, lesion level, IQ, and the dependent variables at the prior wave as covariates.

RESULTS

Bootstrapped mediation analyses revealed that PPCV significantly mediated the relationship between maternal distress and youth responsibility for medical tasks such that higher levels of distress at Time 1 predicted higher levels of PPCV at Time 2 and lower youth medical responsibility at Time 3. Furthermore, self-reported maternal overprotection significantly mediated the relationship between maternal PPCV and youth responsibility for medical tasks.

CONCLUSIONS

Maternal personal distress, PPCV, and self-reported overprotection are interrelated and affect youth's condition-related responsibility. Interventions for mothers of youth with SB that target these factors may improve both maternal and youth outcomes.

Longitudinal Associations Between Pain and Psychosocial Adjustment in Youth With Spina Bifida

OBJECTIVE

This study examined: (a) the nature and prevalence of pain in youth with spina bifida (SB) (b) common coping responses to pain, and (c) longitudinal, bi-directional associations between internalizing symptoms and pain characteristics.

METHODS

Data were collected from youth (N = 140, 53.6% female, ages 8-15 at Time 1) and their parents and teachers at two time points spaced 2 years apart. Youth reported on several pain characteristics and coping responses. Multiple informants reported on child internalizing symptoms. Evaluation of Aims 1-3 was based on descriptive analyses, bivariate correlations, and linear and logistic regressions.

RESULTS

About 25% of the sample reported chronic pain (e.g., experiencing pain one or more times per week over the past 3 months) at Time 1 or 2, with roughly one-third of this chronic pain subsample reporting chronic pain both time points. Pain was usually rated as mild in intensity for the full sample and most commonly experienced in the head, abdomen, and back, and described as "aching." Youth with chronic pain reported significantly higher pain intensity and tended to use condition-specific methods to cope with pain (e.g., taking off braces). In 2 of 10 analyses, internalizing symptoms at Time 1 were associated with chronic pain and pain intensity at Time 2.

CONCLUSIONS

Roughly one-fourth of youth with SB are at risk for experiencing chronic pain, highlighting the need for increased assessment and treatment of pain in this population. Youth psychological functioning appears to more often precede, rather than being a consequence of pain symptoms.

The timing and prevalence of intraoperative hypotension in infants undergoing laparoscopic pyloromyotomy at a tertiary pediatric hospital

BACKGROUND

Intraoperative hypotension may be associated with adverse outcomes in children undergoing surgery. Infants and neonates under 6 months of age have less autoregulatory cerebral reserve than older infants, yet little information exists regarding when and how often intraoperative hypotension occurs in infants.

AIMS

To better understand the epidemiology of intraoperative hypotension in infants, we aimed to determine the prevalence of intraoperative hypotension in a generally uniform population of infants undergoing laparoscopic pyloromyotomy.

METHODS

Vital sign data from electronic records of infants who underwent laparoscopic pyloromyotomy with general anesthesia at a children's hospital between January 1, 1998 and October 4, 2013 were analyzed. Baseline blood pressure (BP) values and intraoperative BPs were identified during eight perioperative stages based on anesthesia event timestamps. We determined the occurrence of relative (systolic BP <20% below baseline) and absolute (mean arterial BP <35 mmHg) intraoperative hypotension within each stage.

RESULTS

A total of 735 full-term infants and 82 preterm infants met the study criteria. Relative intraoperative hypotension occurred in 77%, 72%, and 58% of infants in the 1-30, 31-60, and 61-90 days age groups, respectively. Absolute intraoperative hypotension was seen in 21%, 12%, and 4% of infants in the 1-30, 31-60, and 61-90 days age groups, respectively. Intraoperative hypotension occurred primarily during surgical prep and throughout the surgical procedure. Preterm infants had higher rates of absolute intraoperative hypotension than full-term infants.

CONCLUSIONS

Relative intraoperative hypotension was routine and absolute intraoperative hypotension was common in neonates and infants under 91 days of age. Preterm infants and infants under 61 days of age experienced the highest rates of absolute and relative intraoperative hypotension, particularly during surgical prep and throughout surgery.

A Technical Evaluation of Wireless Connectivity from Patient Monitors to an Anesthesia Information Management System During Intensive Care Unit Surgery

Surgical procedures performed at the bedside in the neonatal intensive care unit (NICU) at The Children's Hospital of Philadelphia were documented using paper anesthesia records in contrast to the operating rooms, where an anesthesia information management system (AIMS) was used for all cases. This was largely because of logistical problems related to connecting cables between the bedside monitors and our portable AIMS workstations. We implemented an AIMS for documentation in the NICU using wireless adapters to transmit data from bedside monitoring equipment to a portable AIMS workstation. Testing of the wireless AIMS during simulation in the presence of an electrosurgical generator showed no evidence of interference with data transmission. Thirty NICU surgical procedures were documented via the wireless AIMS. Two wireless cases exhibited brief periods of data loss; one case had an extended data gap because of adapter power failure. In comparison, in a control group of 30 surgical cases in which wired connections were used, there were no data gaps. The wireless AIMS provided a simple, unobtrusive, portable alternative to paper records for documenting anesthesia records during NICU bedside procedures.
