Randomized Controlled Trial Clinical Trial
Hypnosis reduces distress and duration of an invasive medical procedure for children.
Voiding cystourethrography (VCUG) is a commonly performed radiologic procedure in children that can be both painful and frightening. Given the distress that some children experience during the VCUG and the need for children to be alert and cooperative during the procedure, finding a psychological intervention that helps children to manage anxiety, distress, and pain is clearly desirable. This study was designed to examine whether relaxation and analgesia facilitated with hypnosis could reduce distress and procedure time for children who undergo this procedure. ⋯ Hypnotic relaxation may provide a systematic method for improving the overall medical care of children with urinary tract abnormalities and may be beneficial for children who undergo other invasive medical procedures. Because the VCUG is an essential part of the evaluation of urinary tract infections and vesicoureteral reflux in children, lower distress during the procedure may improve patient and family compliance with initial as well as follow-up evaluations. These findings augment the accumulating literature demonstrating the benefits of using hypnosis to reduce distress in the pediatric setting. The present findings are noteworthy in that this study was a controlled, randomized trial conducted in a naturalistic medical setting. In this context, we achieved a convergence of subjective and objective outcomes with moderate to large effect sizes, including those that may have an impact on patient care and procedure cost, that were consistently supportive of the beneficial effects of hypnosis-a noninvasive intervention with minimal risk. The findings, therefore, have immediate implications for pediatric care. Limitations of this study include the lack of participant and staff blindness to the child's condition assignment, which could have introduced bias into reports. However, the objective procedural time differences between groups were consistent with the other, more subjective outcome findings. The sample was also small and primarily white in ethnic/racial makeup, which may have restricted our ability to detect some differences and may limit the generalizability of findings to more representative samples. In addition, the sample comprised children who had already undergone at least 1 VCUG during which they had had difficulty. Consequently, additional research is needed to determine whether hypnosis would be helpful to those who are undergoing their first VCUG. Additional limitations, clinical observations, and directions for future research are also discussed.

Utility of bedside bladder ultrasound before urethral catheterization in young children.
Urethral catheterization is the method of choice for obtaining samples for urine culture and urine analysis in infants. Before the procedure, there is little certainty of the presence or amount of urine in the bladder. Consequently, this relatively invasive and uncomfortable procedure often needs to be repeated. The newly available technology of portable ultrasound may be useful in reducing the number of unsuccessful procedures. ⋯ A rapid bedside ultrasound of the bladder performed by pediatric emergency physicians led to an increased success rate of urethral catheterization in children who were younger than 2 years. We were able to avoid repeated invasive testing with a simple noninvasive procedure.

Comparative Study
Evaluation of a new combined transcutaneous measurement of PCO2/pulse oximetry oxygen saturation ear sensor in newborn patients.
Arterial oxygen saturation (Sao(2)) and arterial carbon dioxide partial pressure (Paco(2)) are 2 of the most important respiratory parameters in the treatment of critically ill neonates. Noninvasive monitoring of these parameters is desirable for continuous estimating of the respiratory status and reducing blood loss because of repeated blood gas analyses. Transcutaneous measurement of Pco(2) (Ptcco(2)) represents a simple and noninvasive technique for continuous monitoring of ventilation. However, sensor preparation, positioning, taping, and repeated changes of the sensor location make the handling difficult and complicate its use in the neonatal care unit. Recently, a new sensor for combined assessment of pulse oximetry oxygen saturation (Spo(2)) and Ptcco(2) has been introduced (TOSCA Monitor; Linde Medical Sensors, Basel, Switzerland). The monitor combines pulse oximetry and Ptcco(2) measurement in a single ear sensor, which works at 42 degrees C to enhance blood flow in capillaries below the sensor. ⋯ The TOSCA monitor with the ear sensor adapted to ears of neonates allows reliable estimation of Sao(2) and Paco(2). A potential benefit is the reduction in motion artifacts because of less head movement in newborns and that only a single cable leads form the patient to the monitor. In addition, the sensor is not removed for chest radiograph or for nursing the infant on his or her parent's lap. Long-term studies in a large population with continuous measurements are required to confirm these preliminary findings and to elucidate the benefits in detection of respiratory deterioration and the potential side effects of this sensor.

Respiratory syncytial virus (RSV) bronchiolitis is a common cause of hospitalizations in children and has been increasingly identified as a risk factor in the development of asthma. Little is known about what determines the severity of RSV bronchiolitis, which may be helpful in the initial assessment of these children. ⋯ The severity of RSV bronchiolitis early in life seems modified by postnatal maternal cigarette smoke exposure and atopy and age of the infant, not by levels of allergens in the home environment.

Pediatric hospitalist systems are being implemented widely. Their implementation may be influenced by physician attitudes, which may vary according to practice type (eg, community or hospital-based practice) and personal characteristics (eg, age and practice location). Little evidence exists to describe factors relevant to pediatric systems. The objective of this study was to determine physicians' attitudes regarding hospitalists and associated physician and practice characteristics. ⋯ Attitudes regarding hospitalist systems differ between physician groups and are influenced by practice characteristics. Understanding these differences and tailoring hospitalist systems to address them will be important as pediatric hospitalist systems are implemented nationwide.
