The effect of an advanced cardiac life support course on advanced cardiac life support ability.

Thousands of health care providers spend time, money, and energy each year taking the AHA-sponsored ACLS courses, and ACLS-certified health care providers are frequently given greater job responsibility than other health care providers in the same setting. The purpose of this study was to determine the effect of an ACLS course on the ability of health care providers to perform ACLS in a simulated situation. A nonequivalent control group design was used. The sample consisted of 76 health care providers whose job responsibilities included ACLS. The Mega-Code skill station from the ACLS course was used to evaluate ACLS performance. Chi-square analyses showed a significant (p less than 0.05) difference in the posttest pass/fail results of the two groups and a significant (p less than 0.05) difference in the changes from pretest to posttest of the two groups. The research hypotheses were supported, and the researches concluded that the course had a positive effect on the subjects' ACLS ability.

Pain reduction interventions during neonatal circumcision.

The purpose of this study was to determine the effect of some noninvasive pain reduction interventions on pain in 121 neonates undergoing unanesthetized circumcision. Subjects were randomly assigned to one of six groups: classical music, intrauterine sounds, pacifier, music and pacifier, intrauterine sounds and pacifier, or control (no nurses present and no pain reduction interventions used). Physiological variables that were monitored were heart rate, rhythm, dysrhythmias, blood pressure, transcutaneous oxygen (tcpO2), rate pressure product, and behavioral state, measured during 14 circumcision steps. Over the 14 steps, 42% of the heart rates, 78% of the systolic blood pressures (SBP), 30% of the diastolic blood pressures (DBP), and 81% of the tcpO2 pressures were abnormal. Few significant differences were found among any of the steps. SBP and DBP differed significantly between groups during two of the noninvasive steps; and tcpO2 differed significantly during six steps.

Skin ulcers of elderly surgical patients in critical care units.

The problem of skin ulcers in elderly surgical patients in critical care units is a serious one. Patients with skin ulcers suffer from pain, disfigurement, immobility, septicemia, and sometimes death. Critical care nurses can provide preventive techniques by understanding the complex relationship among the variables causing skin ulcers in elderly patients. The authors describe the variables most related to skin ulcers in elderly surgical patients.

Pain reduction during neonatal circumcision.

PURPOSE: To determine the effect of two comfort interventions during unanesthesized circumcision on neonatal pain. METHODOLOGY: Fifty-eight neonates were randomly assigned to one of three intervention groups. Eighteen control infants received routine care, 15 infants had music played, and 15 infants had a tape of intrauterine sounds played. During circumcision, monitors measured cardiac rate, rhythm, blood pressure, and transcutaneous oxygen. Pain was measured by analysis of videotaped facial expressions using Izard's Maximally Discriminative Facial Movement Coding System (1983). RESULTS: Mean heart rate was above normal limits during all steps of the circumcision for the control group and during some of the steps for the other two groups. Facial expressions analyzed showed all three groups had pain much more than any other emotion during the procedure. CONCLUSIONS: The two interventions were unable to offset the effects of circumcision pain.
