Efficacy of Prednisolone in bronchiolitis with and without family history of atopy

OBJECTIVE

To determine decrease in respiratory distress and hospital stay in bronchiolitis patients with and without family history of atopy when treated with prednisolone.

METHODS

The multi-centre quasi-experimental study was conducted in three hospitals of Sialkot, Pakistan, from October 2017 to March 2018, and comprised patients of bronchiolitis who were divided into 2 groups on the basis of presence or absence of family history of atopy. Half of the patients in each group received oral prednisolone 2mg/kg/day for three consecutive days along with supportive care, and the remaining half received only supportive care. Patients were monitored at 12 and 24 hours for clinical response using Modified Respiratory distress Assessment Instrument score. Length of hospital stay was monitored upto 72 hours. SPSS 20 was used for data analysis.

RESULTS

Of the 212 patients, 72(34%) were in the atopic group and 140(66%) in the non-atopic group. In atopic group, there was a significant respiratory distress difference observed between steroid and non-steroid subgroups at 24 hours (p=0.001) and all (100%) patients in the steroid subgroup got discharged at 24 hours, while only 8(22%) were discharged in the non-steroid subgroup. In non-atopic group, no significant improvement in corresponding terms was observed (p>0.05).

CONCLUSIONS

Oral prednisolone in bronchiolitis was found to be only effective in patients with family history of atopy.

Outcome Of Use Of Nasal Continuous Positive Airway Pressure Through Infant Flow Drivers In Neonates With Respiratory Distress In A Tertiary Care Hospital In Pakistan

BACKGROUND

Nasal continuous positive pressure has been used for management of respiratory distress in neonates in various conditions as a primary modality. Objective of the study is to evaluate the frequency of improved outcome and complications of use of nasal CPAP through infant flow drivers in neonates with respiratory distress. The study was conducted from 2nd April 2017 to 2nd October 2017 in neonatal intensive care unit of Allama Iqbal Memorial Teaching Hospital Sialkot.

METHODS

All neonates with respiratory distress fulfilling the clinical criteria (Neonates with gestational age 28 weeks to 40 weeks having clinical signs of respiratory distress classified according to down score (tachypnea, grunting, decreased air entry, cyanosis, recessions), neonates having pc02 <60 mmhg, neonates having x-ray findings consistent with respiratory distress syndrome (RDS), Transient tachypnea of newborn (TTN) and pneumonia) were included in the study. Nasal CPAP was used at variable settings. Outcome, complications, indications, associated diseases and hospital stay along with other baseline characteristics were assessed. Success was defined as improvement of the respiratory distress as assessed by down score, maintenance of SPO2 above 90% in room air after weaning from CPAP for about consecutive 4 hours and normalization of blood gases while the failure as need for mechanical ventilation.

RESULTS

Total 60 neonates were included in the study. Mean weight was 2113.3±580.32 g while mean gestational age was 33.35±2.59 weeks. Total 52 (86.7%) babies were successfully weaned off from nCPAP while only 8 (13.3%) neonates required mechanical ventilation. Main indication of use of CPAP was RDS (65%). No complications were observed in 73.3% babies while 26.7% had complications of which nasal deformities accounted for 20% and abdominal distension for 6.37%.

CONCLUSIONS

Nasal CPAP can be safely and easily used as primary support for neonates with respiratory distress even in resource limited developing countries. It reduces the need for mechanical ventilation and thus hospital stay.
