Assessment and management of pain in the critically ill pediatric patient.

Alhough considerable progress has been made in the past decade in the study of pain in children, numerous myths, inadequate assessment, and insufficient knowledge of available treatment continue to contribute to the lack of effective management of children's pain. Clinicians who lack knowledge have misconceptions about pain contribute more to the problem than to the problem's solution. Adequate analgesia is to be provided to even the sickest child the medications, techniques, and approaches reviewed here.

The natural connection: the clinical nurse specialist and bedside nursing research.

The educational preparation and consistent clinical focus of CNSs position them ideally for conducting research at the bedside and helping staff nurses see the relevance of such research. Our research studies have identified a new category of clinical nursing research termed bedside nursing research. Like its parent category of clinical nursing research, the function of bedside nursing research is to generate new knowledge or validate and expand previously generated knowledge. Characteristics that distinguish bedside nursing research from other forms of clinical nursing research are: focus, idea stimulus and setting, originator of the research question, relationship with theory, sensitivity to changing technology in health care, and impact on nursing practice. To illustrate the nature and outcome of this type of research, we describe three bedside nursing research studies conducted by CNSs in a pediatric oncology setting. These studies assessed: (1) the effects of chest tube stripping on the incidence of pain, fever, and pulmonary complications; (2) the relative safety and efficacy of techniques for blood sampling from Hickman catheters; and (3) the effects of infusion method on quality and survival of transfused platelets. The impact of these studies of hospital practices is reviewed.

Chest tube stripping in pediatric oncology patients: an experimental study.

BACKGROUND: Stripping of chest tubes to promote drainage of the thorax of postthoracotomy patients has been routine practice, based on tradition. Recent published findings indicate that significant negative pressures are generated in the tube during stripping that could cause pain, bleeding and possible damage to the patient's lung tissue. OBJECTIVE: To determine whether pediatric oncology patients whose chest tubes were not stripped would differ in frequency of pain, fever or lung complications from patients who underwent routine tube stripping. METHODS: Data were collected at multiple points during the first 72-hour postoperative period from 16 patients assigned to the stripped or unstripped groups. Pain was measured by the Faces Pain Scale and the Visual Analogue Scale; temperature, by electronic thermometer; and lung complications, by stethoscope and radiographs. Both groups, which were comparable for age, primary diagnosis and prior history of lung problems, received identical supportive nursing and medical care, with the physicians blind to group assignment. RESULTS: The two groups did not differ significantly in frequency of pain, incidence of fever, breath sounds or radiographic findings across measurement points. A strong correlation was found between the pain scores using the two instruments. DISCUSSION: Patients whose tubes were not stripped did not have an increased risk of infection or lung complications. Study findings indicated that stripping did not increase the frequency of pain. CONCLUSIONS: Stripping of chest tubes as a routine postoperative measure is questioned.

Infrared, thermistor, and glass-mercury thermometry for measurement of body temperature in children with cancer.

Body temperature is often the sole determinant of whether or not the neutropenic cancer patient is admitted to the hospital for empiric antibiotic therapy. Recently developed infrared tympanic thermometers offer rapid readings, but their accuracy has not been established. We studied two infrared thermometers (FirstTemp and Thermoscan) and a thermistor (IVAC) in children with cancer. Mean infrared measurements did not differ significantly between right and left ear canals, and the mean IVAC temperature did not differ significantly from the left to the right axilla (P greater than 0.05, paired t test). IVAC predictive mode mean temperature was 0.2 degrees C lower than monitor mode mean temperature in the axilla (P less than 0.0001), but 0.1 degree C higher than monitor mode orally (P less than 0.0001). Aiming the infrared instrument at the tympanic membrane using an ear tug resulted in a 0.2 degree C higher mean temperature than casual placement in the ear canal (P less than 0.0001). After compensation for the mean difference in reference oral glass-mercury versus test instrument temperatures, the FirstTemp, Thermoscan, and oral and axillary predictive mode IVAC measurements yielded sensitivities for the detection of fever of 84%, 84%, 82%, and 86%; specificities of 100%, 99%, 100%, and 100%; positive predictive values of 100%, 93%, 100%, and 100%; and negative predictive values of 95%, 98%, 98%, and 98%, respectively. We conclude that each of these instruments detects fever with comparable reliability. Infrared instruments are especially attractive alternatives due to their time efficiency.
