RESUMO
OBJECTIVES: To determine efficacy of non-invasive positive pressure face mask ventilation using a ventilator device (NIPPmV) for achieving early effective ventilation compared to that by self-inflating bag (SIB) or T- piece resuscitator (TPR). METHODS: The authors video recorded 33 trained resuscitators using NIPPmV (provided using ventilator device), SIB [a 500 ml silicone SIB without a positive end expiratory pressure (PEEP) valve] and a TPR. Using a continuous pressure recording system and a neonatal manikin, the authors evaluated the efficacy of the ventilation to achieve early effective ventilation during 30 s of ventilation. The primary outcome was time to achieve effective chest rise. Secondary outcomes were peak inspiratory pressure (PIP), ventilation rate and the need to perform ventilation corrective steps during positive pressure ventilation (PPV) among the devices. RESULTS: Total 99 videos were recorded. The time(s) taken to achieve the first chest rise was significantly lesser in NIPPmV group compared to SIB and TPR (3.0 ± 1.7 vs. 3.7 ± 1.9 vs. 7.5 ± 5.4, respectively, p <0.001). The mean PIP delivered by NIPPmV compared to SIB & TPR (19.8 ± 1.6 vs. 35.6 ± 7.4 vs. 17.8 ± 2.0 cm H20 respectively; p <0.001) was more accurate with preset PIP. Ventilation, in terms of breath rate, was observed to be controlled more accurately with NIPPmV compared to SIB & TPR (50 vs. 42 vs. 33 per min respectively; p <0.001). CONCLUSIONS: The non-invasive positive pressure face mask ventilation using a ventilator (NIPPmV) resulted in achieving early, effective and consistent ventilation.
RESUMO
Shailesh KanvindeBackground To enable outpatient department (OPD) management of febrile neutropenia (FN), we used once-a-day (OD) ceftriaxone-amikacin (CFT-AMK) as empiric antibiotic therapy. Our experience over 16-year period is presented. Methods This was a retrospective study conducted from January2002 to December2017. Inclusion criteria were <18 years of age, undergoing cancer chemotherapy, and having FN. Exclusion criteria were FN after palliative chemotherapy, bone marrow transplantation, or at diagnosis of malignancy. Empiric CFT-AMK was used in all, except those having respiratory distress, hypotension, altered sensorium, paralytic ileus, or clinical evidence of peritonitis. Admission criteria were age <1 year, acute myeloid leukemia (AML) chemotherapy, poor performance status, need for blood transfusions, convenience, insurance, or persistent fever >48 to 72 hours after CFT-AMK. Outcomes analyzed were response (defervescence within 48-72 hours), OPD management, antibiotic upgrade, and mortality. AML diagnosis, >7 days to absolute neutrophil count >0.5 × 10 9 /L, poor performance status, and malignancy not in remission were considered high-risk FN criteria. Results CFT-AMK was given in 877/952 (92.2%) FN episodes. Seventy-six percent had hematolymphoid malignancies. Response, antibiotic upgrade, and mortality were seen in 85.7 and 65.5% ( p < 0.0001), 15 and 45.5% ( p < 0.0001), and 0 and 2% ( p = 0.003) of low- and high-risk patients, respectively. Treatment was started in OPD in 52%, of which 21.6% required subsequent admission. Of those initially admitted, early discharge (hospital stay < 5 days) was possible in 24.6%. Forty-one percent episodes were managed entirely on OPD. Overall, 80% of low-risk and 42% of high-risk episodes received treatment wholly or partially on OPD. Conclusion Our results show empiric OD CFT-AMK allows OPD management for most of the low-risk and a proportion of high-risk FN following chemotherapy in children, without compromising clinical outcomes.
RESUMO
Calciphylaxis, also known as calcific uremic arteriolopathy, is a rare, life-threatening complication of end-stage renal disease. However, it may also occur in patients without renal failure, the nonuremic calciphylaxis. Most patients present with painful skin ulcers. Delayed diagnosis can lead to sepsis-related morbidity and mortality. Aberrations in calcium, phosphate, and parathyroid hormone physiology are common and biopsy is diagnostic. Early diagnosis and correction of vascular and metabolic aberrations may assist in healing as may the use of sodium thiosulfate and hyperbaric oxygen therapy. We report on successful treatment of a case of calciphylaxis in a renal transplant recipient with normal allograft function.
