The physiologic changes in pregnancy occur in response to fetal development and eventual delivery. It is incumbent on the intensive care physician to have an understanding of the normal variants that occur in pregnancy to correctly interpret diagnostic tests and effectively treat clinical conditions. Some changes that occur in pregnancy include the following. Endocrine changes
The Effects of Nitrous oxide in neuroanaesthesia has been questioned many times due to its detrimental effects on the cerebral vasculature and the brain tissue. However, there are no large-scale outcome studies to approve or disapprove its continued use in neuroanaesthesia. Nitrous oxide has been used in neuroanaesthesia for many years. Intraoperative analgesia with haemodynamic
There is very little airway irritation, hence used for inhalation induction especially in children. One of the halothane respiratory effects is that it is a potent respiratory depressant, reduces tidal volume and alveolar minute ventilation. The ventilatory response to raised Paco2 and reduced Pao, may be reduced due to depression of peripheral chemoreceptors in the
Chronic pain is a persistent condition that affects millions of people worldwide. It can be debilitating and significantly impact a person’s quality of life. Fortunately, there are various strategies and approaches available to help manage chronic pain effectively. In this article, we will explore some of the commonly used chronic pain management strategies. 1. Medication:

Desflurane is an inhalational agent used in anesthesia that is similar to isoflurane except the chlorine atom of isoflurane is replaced by fluorine atom which produces significant changes in physical properties. Physical Properties of Desflurane : It is colorless liquid. Pungent odor, so induction is not pleasant. Vapor pressure of Desflurane is very high (681
The Upper Respiratory Anatomy starts with the nose, which is an essential organ for breathing and conditioning of the air. The main respiratory functions of the nose are to provide passage to the air as well as the warming and moistening of the air. The next part is the pharynx, which is further divided into
Introduction to Pediatric Weight Calculation Calculating the body weight of pediatric patients is a crucial skill for healthcare providers, particularly in emergency situations. Accurate weight estimation not only facilitates proper medication dosing but also ensures appropriate fluid administration. To streamline this process, guidelines from both the Pediatric Advanced Life Support (PALS) program and the World

Neuroleptanalgesia Neuroleptanalgesia is method of IV anesthesia which combines at neuroleptic drug with opioid analgesic drug. The most favored combination is neuroleptic droperidol and the analgesic fentanyl. The combination used neuroleptanalgesia induces state which is different from usual general anesthesia. Because the patient is awake during surgery and is cooperative during the operative and surgical
Enflurane metabolism is briefly discussed. About 80-90% of enflurane is eliminated in expired air, up to 5% is metabolized by hepatic cytochrome P450 (2E1) to difluoromethoxy difluoroacetic acid and free fluoride. Carbon monoxide may be produced in the presence of dry soda lime or baralyme, at higher temperatures and higher anaesthetic concentrations. Also while studying
A lot of anesthetic gases can be dangerous when used in a low alveolar ventilation anesthesia. This is because the anesthetic gases can combine with soda lime or other components of the boyles machine and produce poisonous gases. It is also known as low flow anesthesia where low fresh gas flow is set in a closed circuit or a semi closed
