Capillary refill time in term neonates: bedside assessment.

Capillary refill time (CRT) is yet to be established as a specific clinical sign of peripheral circulation in neonates. This study was conducted to assess the influence of four body sites used for measurement, interobserver variability, sex, birth weight, age at assessment and room temperature on CRT recorded in healthy term neonates, at bedside. Two observers measured CRT in four different body sites (forehead, chest, palm and heel) of each of 155 healthy term neonates. Significant differences occurred between the mean CRT recorded by the two observers in forehead (mean +/- SD: 2.62 +/- 0.8 s and 1.88 +/- 0.57 s; p < 0.001), palm (2.99 +/- 0.61 s and 2.75 +/- 1.12 s; p < 0.05) and heel (3.08 +/- 0.79 s and 4.24 +/- 1.84 s; p < 0.001). Only CRT in chest (2.7 +/- 0.42 s and 2.62 +/- 0.74 s) produced no significant differences in the means with a statistically significant and clinically fair, but not strong, interobserver agreement (r = 0.4; p < 0.001). No significant associations occurred between CRT and sex or birth weight. The associations of chest CRT with age at assessment (r = -0.23; p < 0.01) and room temperature (r = 0.27; p < 0.01) were clinically not important. In conclusion, CRT in neonates needs to be validated further before it can be useful as a specific clinical sign of peripheral circulation.

Clinico-bacteriological study of neonatal septicemia in Hubli.

Septicemia is a leading cause of neonatal morbidity and mortality in India. In a study of 242 infants with septicemia conducted between March 1996 & June 1997 at Hubli, Karnataka, 43.39% infants had 'very early onset' sepsis (VOS), 40.08%, had 'early onset' sepsis (EOS), and 16.53% 'late onset' sepsis (LOS). 54.55% neonates had birth weight below 2000 g and 39.67% were born before 37 weeks of gestation. The cardiorespiratory signs and jaundice were the most frequent clinical features. The blood culture positivity rate was 64.87%. Klebsiella species was the commonest causative pathogen found and multidrug resistance was frequent. The overall mortality rate was 47.52% and the case fatality rate in LOS was higher than in VOS and EOS (p < 0.001). The mortality was significantly higher in neonates with lower birth weight and lower gestational age (p < 0.001). The study underlines the importance of monitoring the various features of neonatal septicemia, as well as the drug resistance of the pathogens from the nurseries.
