Delayed timing of intrauterine insemination results in a significantly improved pregnancy rate in female partners of quadriplegic men.

OBJECTIVE: To review pregnancy rates obtained with three protocols used during development of a successful therapy for infertility in couples in which the male partner had spinal cord injury. DESIGN: Retrospective chart review. SETTING: Private infertility center. PATIENT(S): Eleven quadriplegic men and their spouses undergoing intrauterine insemination. INTERVENTION(S): Protocol 1: Intrauterine insemination was performed 24 hours after the LH surge was detected in unstimulated cycles. Sperm were prepared by standard sperm washing. Protocol 2: Female partners were stimulated with clomiphene citrate and hCG. Sperm were inseminated 32-34 hours after hCG injection. Sperm preparation was by serum swim-up or density gradient preparation. Protocol 3: Identical to protocol 2, except the insemination was delayed to 38-40 hours after hCG injection. MAIN OUTCOME MEASURE(S): Pregnancy rates. RESULT(S): Five patients were enrolled into protocol 1 and underwent a total of 19 inseminations with no subsequent pregnancies. They then underwent protocol 2, but no pregnancies resulted from inseminations. Four of the original couples, along with six additional couples, underwent insemination in protocol 3. A total of 19 inseminations were performed, and 6 of the 10 patients (60%) became pregnant. The success of insemination at 38-40 hours after hCG administration was significantly better than that of the initial two protocols (P<.05). No differences were observed in sperm quality between protocol 2 and protocol 3. Overall, 73% (8 of 11) of the patients became pregnant. CONCLUSION(S): Intrauterine insemination 38-40 hours after the hCG injection results in an improved chance of pregnancy. These results indicate that many couples with spinal cord injury-associated male infertility can be treated with intrauterine insemination of sperm treated by serum swim-up, with a high probability of success.

A comparison of continuous infusion and intermittent flushing methods in peripheral intravenous catheters in neonates.

The purpose of this study was to compare two methods of maintaining peripheral intravenous devices in neonates: continuous infusion (CI) and intermittent flushing (IF). There was no significant difference in the mean duration of patency between the two groups, but there was a significant difference with respect to reasons for removal or loss of patency. The main reason for removal in the CI group was infiltration or phlebitis, and in the IF group the reason was occlusion.

A new measure of parent satisfaction with medical care provided in the neonatal intensive care unit.

The objective of this study was to develop a valid and reliable discriminative index that measures parent satisfaction with the medical care of their infant in the NICU. We developed an initial questionnaire (Item Reduction Questionnaire) by reviewing the literature, surveying 63 NICU clinicians, and interviewing 125 parents of infants in 2 tertiary level NICUs regarding what they liked and disliked about the medical care of their infants. We administered the Item Reduction Questionnaire, which included 154 items, to 60 parents, who rated the frequency and importance of these items. We included the items identified most frequently as sources of dissatisfaction and rated most important in a second, briefer instrument, the Neonatal Index of Parent Satisfaction (NIPS). To measure reliability we administered the NIPS to 47 parents twice, separated by a 1-week interval. We assessed validity by comparing actual to predicted correlations between NIPS scores and other measures: parent's global rating of satisfaction, medical caregiver ratings of mother's satisfaction, medical caregiver ratings of father's satisfaction, and parents' perception of their infant's health status. We also compared mean NIPS scores for parents who did and who did not report incidents when errors occurred in the medical care of the infant. Of 154 items generated, we included 27 in the NIPS. The intraclass correlation between two administrations of the NIPS to the same 47 parents was 0.71. As predicted, there was a high correlation (0.61) between the NIPS score and parent global rating of satisfaction, and much lower correlations with other variables. Mean NIPS scores for parents who did and who did not report errors differed significantly (difference, 14.6; 95% CI around difference, 5.8-23.5; p < 0.001). The NIPS is likely to be a useful measure for discriminating between parents who differ in terms of their satisfaction with the medical care of their infant in the NICU.

Definition of an advanced nursing practice role in the NICU: the clinical nurse specialist/neonatal practitioner.

We surveyed 655 health professionals affiliated with tertiary level neonatal intensive care units in Canada and the United States to define an expanded role for nurses in neonatology and to determine the educational requirements for the role. The role, comprising advanced clinical practice, educational, research, and administrative responsibilities, is a blend of nurse practitioner and clinical nurse specialist activities. Based on survey findings, a neonatal stream within the existing Master of Health Sciences program at McMaster University was developed. To date, 15 clinical nurse specialists/neonatal practitioners (CNS/NPs) are employed in five neonatal intensive care units in Ontario and other related institutions. A randomized trial to evaluate these individuals is in progress.

Suctioning Newborns: A practical guide to when and how.

All medical personnel involved in perinatal care are responsible for stabilizing the newborn at delivery. The initial step in resuscitation both in the delivery room and in the neonatal unit is ensuring patency of the airway through proper, efficient suctioning. This article outlines a systematic approach to the procedure.

Evaluation of graduating neonatal nurse practitioners.

To compare the knowledge and problem-solving, communication, and clinical skills of graduating neonatal nurse practitioners (NNPs) and pediatric residents, a cohort study was conducted in a 33-bed tertiary-level neonatal intensive care unit in a 400-bed teaching hospital affiliated with a faculty of health sciences. Participants were all (n = 10) NNP graduates from the first 3 years of the educational program and 13 (87%) of 15 second-year pediatric residents. One hundred multiple-choice questions and 20 radiographic slides were used to test knowledge; a semistructured oral examination tested problem-solving skills; three simulated interactions with parents tested communication skills; and seven simulated procedures tested clinical skills. Graduating NNPs scored similarly to the pediatric residents on the multiple-choice questions (difference -3.4%; 95% confidence interval [CI] around difference -9.7, 2.9), radiographs (difference -1.4%; 95% CI -11.5, 8.7), oral examination (difference 2.8%; 95% CI -11.1, 16.7), communication skills (simulated parents assessment: difference 0.8%; 95% CI -4.2, 5.7; expert observer assessment: difference 5.8%; 95% CI -2.8, 14.3), and clinical skills (difference 7.4%; 95% CI -5.5, 20.2). The NNPs about to graduate from their educational program showed knowledge and problem-solving, communication, and clinical skills equivalent to those of second-year pediatric residents and are thus likely to deliver comparable care in the clinical setting. The results support the adoption of the NNP role.

Peritoneal dialysis in the neonate.

The etiology of renal failure in the newborn infant is multifactorial. The increasing survival of low-birthweight infants and the aggressive drug management of pathophysiological disease states such as pulmonary hypertension and patent ductus arteriosus has resulted in an increase in the number of infants presenting with acute renal failure. Experience in our intensive care unit has proved that early intervention with peritoneal dialysis is safe and may significantly reduce both morbidity and mortality in such patients.

Intravenous infusion by superficial vein in the neonate.

State-of-the-art equipment, such as extremly-low-volume controlled infusion pumps and Teflon catheters, has simplified the management of intravenous therapy in the newborn. This article details the proper I.V. insertion procedure for neonates. It also reviews indications for neonatal infusion, preferred insertion sites, types of catheters currently in use, and potential complications relevant to neonatal intravenous care.

Neonatal Cardio-pulmonary Arrest: Emergency Catheterization of Umbilical Vein.

In an emergency, the physician responsible for neonatal care must be skilled in umbilical catheterization. Several drugs can be given through an endotracheal tube, but some require intravenous administration. The umbilical vein is a better route of administration than peripheral veins because it is easily located and can be entered readily. It allows immediate access to the central circulation, enhancing drug distribution. The authors outline the procedure in a step-by-step description. This pictorial article can be used as a handy reference by physicians needing to administer fluids and drugs during cardio-pulmonary arrest in neonates.

Medical staffing in Ontario neonatal intensive care units.

Advances in technology have improved the survival rates of infants of low birth weight. Increasing service commitments together with cutbacks in Canadian training positions have caused concerns about medical staffing in neonatal intensive care units (NICUs) in Ontario. To determine whether an imbalance exists between the supply of medical personnel and the demand for health care services, in July 1985 we surveyed the medical directors, head nurses and staff physicians of nine tertiary level NICUs and the directors of five postgraduate pediatric residency programs. On the basis of current guidelines recommending an ideal neonatologist:patient ratio of 1:6 (assuming an adequate number of support personnel) most of the NICUs were understaffed. Concern about the heavy work pattern and resulting lifestyle implications has made Canadian graduates reluctant to enter this subspecialty. We propose strategies to correct staffing shortages in the context of rapidly increasing workloads resulting from a continuing cutback of pediatric residency positions and restrictions on immigration of foreign trainees.
