ABSTRACT
AIM: To audit the identification and screening of graduates from a neonatal intensive care unit with risk factors for sensorineural hearing loss. METHODS: Hospital medical records of newborn infants discharged from the neonatal intensive care unit, Christchurch Womens Hospital, between 1 July 1994 and 30 June 1995 (n=564), were examined to identify those at risk for sensorineural hearing loss according to the American Speech-Language Hearing Association risk criteria 1991. Auditory brainstem response test results were obtained from the Christchurch Hospital Audiology Department. Outcome measures were: presence of hearing loss risk factors, numbers tested with auditory brainstem response, age at test and presence and degree of hearing impairment. RESULTS: Of 5,215 live births in Christchurch, 564 infants were discharged through the neonatal intensive care unit. Of these, 86 had risk factors for sensorineural hearing loss. There were 72 (84%) infants tested at audiology, with fifteen (17%) having abnormal test results. There were fourteen with risk factors who did not get audiology screening. CONCLUSION: A high proportion (84%) of high risk newborn infants had auditory brainstem response testing. Further improvement would require strict implementation of standard procedures. Auditory brainstem response screening is part of a wider population surveillance approach to identify hearing loss as early as possible.

A prospective study was performed between April 1, 1991 and April 30, 1992 to determine factors involved in the development of post-Caesarean section wound infection. During this period there were 4,857 deliveries, 428 by Caesarean section (8.8%). Complete data were available on 328 (76.6%) patients. Wound infection occurred in 25.3% of women and was confirmed by positive bacteriology in 77.1%; 36% of wound infections were diagnosed following the patients' discharge from hospital. A negative correlation was found between maternal age and development of wound infection up to age 40 (p = 0.03). Maternal weight was a highly significant indicator of subsequent wound infection development (p = 0.0001), the relationship between increasing maternal weight and infection appearing linear. Antibiotic prophylaxis was found to be the most significant protective factor (p = 0.0007) in the reduction of postoperative wound infection. This relationship was independent of maternal weight.

The feasibility of attempting a two-stage universal screening test for auditory impairment was assessed at a large district maternity hospital. The first stage was measurement of otoacoustic emissions using the Programmable Otoacoustic Emission Measurement System. Those failing the first stage proceeded to automated analysis of auditory brainsteam responses. A single tester working for 6 h on 6 days per week attempted to test all babies born between the hours of midday and midnight for 2 weeks and then all babies born between midnight and midday for a further 2 weeks. Of 217 babies born during the study periods, one infant died and three were still receiving intensive care at the end of the study. Of the remaining 213 infants, auditory testing was undertaken in 201 infants (94%). Eight infants (4%) who failed the first stage of the screening test did not undergo the second stage. Of those 193 infants completing the screen, one (0.5%) failed the screen unilaterally. There were no bilateral failures. Three testers, working two and a half whole-time equivalents, should be adequate to achieve a coverage of 90% and a specificity of 99% for this screen in this clinical setting.

The case of a child with severe hyperphosphataemia and symptomatic hypocalcaemia secondary to retention of phosphate administered through an antegrade continence enema is reported. Caution should be exercised with the use of phosphate enemas and prompt action taken to remedy retention. The use of glucose with insulin in the emergency management of acute hyperphosphataemia is discussed.
