Alarm Limits (alarm + limit)
Selected AbstractsDetection and management of decreased fetal movements in Australia and New Zealand: A survey of obstetric practiceAUSTRALIAN AND NEW ZEALAND JOURNAL OF OBSTETRICS AND GYNAECOLOGY, Issue 4 2009Vicki FLENADY Background:, Decreased fetal movement (DFM) is associated with increased risk of adverse pregnancy outcome. However, there is limited research to inform practice in the detection and management of DFM. Aims:, To identify current practices and views of obstetricians in Australia and New Zealand regarding DFM. Methods:, A postal survey of Fellows and Members, and obstetric trainees of the Royal Australian and New Zealand College of Obstetricians and Gynaecologists. Results:, Of the 1700 surveys distributed, 1066 (63%) were returned, of these, 805 (76% of responders) were currently practising and included in the analysis. The majority considered that asking women about fetal movement should be a part of routine care. Sixty per cent reported maternal perception of DFM for 12 h was sufficient evidence of DFM and 77% DFM for 24 h. KICK charts were used routinely by 39%, increasing to 66% following an episode of DFM. Alarm limits varied, the most commonly reported was < 10 movements in 12 h (74%). Only 6% agreed with the internationally recommended definition of < 10 movements in two hours. Interventions for DFM varied, while 81% would routinely undertake a cardiotocograph, 20% would routinely perform ultrasound and 20% more frequent antenatal visits. Conclusions:, While monitoring fetal movement is an important part of antenatal care in Australia and New Zealand, variation in obstetric practice for DFM is evident. Large-scale randomised controlled trials are required to identify optimal screening and management options. In the interim, high quality clinical practice guidelines using the best available advice are needed to enhance consistency in practice including advice provided to women. [source] Improving compliance with pulse oximetry alarm limits for very preterm infants?JOURNAL OF PAEDIATRICS AND CHILD HEALTH, Issue 5 2010Bernice A Mills Objective: To determine if participation in a randomised controlled trial of different oxygen saturation targets improved compliance with oximeter alarm limit guidelines. Design: Eligible infants were born after the commencement of the BOOST II trial. Data on alarm limits were collected on all infants <32 weeks' gestational age or birth weight <1500 g, who were born at The Royal Women's Hospital, Melbourne between February and June 2007, and receiving supplemental oxygen at the time of the audit. The proportions of infants in oxygen with correct alarm limits (upper 94%; lower 85% or 86%) were compared, between those in the BOOST II trial and those who were not, and with an earlier audit. Results: Of 100 infants surveyed, 56 had received oxygen (mean gestational age at birth 26.7 weeks, mean birth weight 913 g). Compliance with lower limits was good in both periods, irrespective of post-menstrual age or participation in the trial. Compliance with upper limits improved after trial commencement, but only for infants enrolled in the trial and only whilst they were <36 weeks' post-menstrual age. Conclusions: Starting a clinical trial of oxygen targeting was associated with improved compliance with upper alarm limits for participants receiving supplemental oxygen, but only whilst they were <36 weeks; with little effect outside the trial.
