Incidence and risk factors of parenteral nutrition-associated cholestasis in Omani neonates single centre experience

Parenteral nutrition-associated cholestasis [PNAC] is one of the most challenging complications of prolonged parenteral nutrition [PN] in neonates. There is a lack of research investigating its incidence in newborn infants in Oman and the Arab region. Therefore, this study aimed to assess the incidence of PNAC and its risk factors in Omani neonates. This retrospective study took place between January and April 2014. All neonates who received PN for >/=14 days during a four-year period [June 2009 to May 2013] at the neonatal intensive care unit [NICU] in Sultan Qaboos University Hospital, Muscat, Oman, were enrolled. A total of 1,857 neonates were admitted to the NICU over the study period and 135 neonates [7.3%] received PN for >/=14 days. Determining the incidence of PNAC was only possible in 97 neonates; of these, 38 [39%] had PNAC. The main risk factors associated with PNAC were duration of PN, duration of enteral starvation, gastrointestinal surgeries, blood transfusions and sepsis. Neonates with PNAC had a slightly higher incidence of necrotising enterocolitis in comparison to those without PNAC. This study found a PNAC incidence of 39% in Omani neonates. There were several significant risk factors for PNAC in Omani neonates; however, after logistic regression analysis, only total PN duration remained statistically significant. Preventive strategies should be implemented in NICUs so as to avoid future chronic liver disease in this population

Factors responsible for the prolonged stay of surgical neonates in intensive care units

The length of hospital stay [HS] for patients is a major concern due to its social, economic and administrative implications; this is particularly important for neonates admitted to intensive care units [ICUs]. This study aimed to determine the factors responsible for prolonged HS in surgical neonates. This retrospective study was conducted at Sultan Qaboos University Hospital, in Muscat, Oman. The medical records of 95 neonates admitted to the neonatal ICU who underwent general surgical procedures between July 2009 and June 2013 were reviewed. Mann-Whitney U and Pearson's Chi-squared tests were used for non-parametric numerical and categorical variables, respectively. A multiple regression analysis was performed to find a relationship between the variables and to detect the most important factor responsible for prolonged HS. A P value of <0.05 was considered statistically significant. Gestational age, birth weight, number of days on a ventilator and postoperative morbidity were associated with prolonged HS. Furthermore, the age of neonates at first full enteral feed was associated with increased HS using both independent and multiple regression analyses. Prolonged HS can occur as a result of many factors. In this study, a number of factors were identified, including low gestational age, low birth weight, increased number of days on a ventilator and postoperative morbidity. Additionally, neonate age at first full enteral feeds also correlated with increased HS. Further research on this topic is suggested to explore this correlation in more detail and to inform future practices

Changing survival rate of infants born before 26 gestational weeks: single-centre study

This study aimed to evaluate the changing survival rate and morbidities among infants born before 26 gestational weeks at the Sultan Qaboos University Hospital [SQUH] in Muscat, Oman. This retrospective study assessed the mortality and morbidities of all premature infants born alive at 23-26 gestational weeks at SQUH between June 2006 and May 2013. Infants referred to SQUH within 72 hours of birth during this period were also included. Electronic records were reviewed for gestational age, gender, birth weight, maternal age, mode and place of delivery, antenatal steroid administration, morbidity and outcome. The survival rate was calculated and findings were then compared with those of a previous study conducted in the same hospital from 1991 to 1998. Rates of major morbidities were also calculated. A total of 81 infants between 23-26 gestational weeks were admitted to the neonatal unit during the study period. Of these, 58.0% were male and 42.0% were female. Median gestational age was 25 weeks and mean birth weight was 770 +/- 150 g. Of the 81 infants, 49 survived. The overall survival rate was 60.5% compared to 41% reported in the previous study. Respiratory distress syndrome [100.0%], retinopathy of prematurity [51.9%], bronchopulmonary dysplasia [34.6%], intraventricular haemorrhage [30.9%] and patent ductus arteriosus [28.4%] were the most common morbidities. The overall survival rate of infants between 23-26 gestational weeks during the study period had significantly improved in comparison to that found at the same hospital from 1991 to 1998. There is a need for the long-term neurodevelopmental follow-up of premature infants

Early versus late parenteral nutrition in very low birthweight neonates: a retrospective study from Oman

The aim of this study was to compare the biochemical parameters, weight gain, osteopenia and phosphate supplementation in very low birth weight [VLBW] neonates receiving early versus late parenteral nutrition [EPN versus LPN]. A retrospective study was undertaken in the level III Neonatal Intensive Care Unit at Sultan Qaboos University Hospital, Oman: from January 2007 to October 2008 [LPN group, n = 47] and from January 2009 to June 2010 [EPN group, n = 44]. Demographic data, anthropometric and laboratory parameters were extracted from the electronic record system. The mean age of PN initiation was LPN = 47.3 hours versus EPN = 14.3 hours. Biochemical parameters analysed during the first week of life revealed a reduction in hypernatraemia [12.7% versus 6.8%] and non-oliguric hyperkalemia [12.7% versus 6.8%] in EPN, with no significant differences in acidosis and urea levels between the two groups. Hyperglycemia >12 mmol/L in <1000g was higher in EPN. Nutritional parameters in 81 babies who survived/stayed in the unit up to a corrected gestational age [CGA] of 34 weeks [40 in LPN and 41 in EPN], revealed a reduction in metabolic bone disease [osteopenia of prematurity [OOP], 17.5% versus 7.3%] and the need for phosphate supplementation [22.5% versus 7.3%] in the EPN group. There was no increase in acidosis or cholestasis. No difference was noted in albumin levels, time to full feeds, time to regain birthweight and mean weight gain per day till 34 weeks corrected CGA. EPN in VLBW newborns is well tolerated and reduces hypernatraemia, non-oliguric hyperkalemia, OOP and the need for phosphate supplementation
