Laryngoscopy and endotracheal intubation can cause hypertension and tachycardia which can result in myocardial ischemia or stroke in vulnerable people. The objective of our study was to compare the efficacy of bolus dose of dexmedetomidine and fentanyl in attenuating haemodynamic stress responses following laryngoscopy and intubation. ⋯ Attenuation of rise in heart rate and blood pressure following laryngoscopy and endotracheal intubation was better with 1mcg/kg of dexmedetomidine when compared to fentanyl.

Clonidine has proved to be effective drug for postoperative analgesia but it's efficacy to alter neuroendocrine stress response and emergence agitation is unknown. This study was conducted to assess and compare the efficacy of caudal fentanyl vs. clonidine for analgesia, blunting of neuroendocrine stress responses (NESR) and emergence agitation (EA) following sevoflurane anaesthesia. ⋯ Caudal clonidine in a dose of 3 μg/kg prolongs analgesia and decreases emergence agitation as compared to bupivacaine alone or with fentanyl 1μg/kg. Modulation of the neuroendocrine stress response was observed in all the investigated groups though the indicators were lowest in clonidine group.

Patients who survive cardiac arrest often develop severe neurological dysfunction due to the hypoxic brain injury and reperfusion induced cell death. Therapeutic hypothermia (TH) has become a standard therapy of cerebral protection following the successful return of spontaneous circulation in patients of out-of-hospital cardiac arrest, according to American heart association guidelines. This is a case report of a 30-year-old patient who developed in-hospital cardiac arrest and was revived after prolonged cardiopulmonary resuscitation (CPR) and also required primary angioplasty. ⋯ The patient was gradually and successfully weaned off from ventilator with no neurological impairment. There is an increasing evidence of TH and its protective mechanisms in patients with non-shockable arrest rhythms with particular emphasis on neurological outcomes. This article emphasizes the role of TH in every successful CPR irrespective of the cardiac rhythm.

Sepsis is one of the major causes of neonatal morbidity and mortality. Early recognition and diagnosis of neonatal sepsis are difficult because of the variable and non-specific clinical presentation of this condition. Hence, there is a need for early predictive screening method for neonatal sepsis. ⋯ The haematological scoring system using cord blood can be considered as an early predictive screening method for detection of early onset neonatal sepsis. Identifying the risk of developing sepsis early can prevent morbidity and mortality of the neonates.

Traditionally Capillary refilling time (CRT) has been used as a widely accepted method to assess cardiac output and peripheral circulation in neonates. There are only few studies describing normal values and the correct method of recording CRT. The value of CRT is affected by various factors like ambient or skin temperature, age, site of measurement, duration as well as amount of pressure and inter observer variation. However, none of these have been standardized. Hence, we conducted this study to establish the normal value and factors affecting Capillary Refilling Time (CRT) in healthy neonates in Varanasi. ⋯ The normal value of capillary refilling time (CRT) in healthy neonate is less than three seconds. The major determinants of CRT in healthy neonate are birth weight, radiant warmer and phototherapy. CRT alone in neonatal age is less informative haemodynamic parameter; it should be evaluated along with either blood pressure or oxygen saturation with pulse oxymeter. Further studies are needed to assess the reliability and validity of CRT as a clinical tool to measure perfusion in neonates.
