Pentazocine injection is a synthetic narcotic analgesic derived from benzomorphan. Pentazocine Potency Its analgesic potency of 30 mg is said to be equal to 10 mg of morphine or 75 to 100 mg of pethidine. Pentazocine Dose The usual dose in adults is 20 to 60 mg i.m. (about 1 mg/kg). The oral dose ranges from […]
High Flow oxygen delivery devices are also called as fixed performance devices because their performance is not affected by changes in patient’s tidal volume and respiratory rate and therefore deliver accurate oxygen concentration. High Flow oxygen devices are more effective in treating hypoxemia then low flow systems. Disadvantages of High Flow oxygen devices are: a. Low patient
Cardiovascular effects of inhalation anesthetics occur on all aspects of cardiovascular function, namely, inotropic, chronotropic, dromotropic and lusitropic state of the heart. Their effects are as follows: a) Myocardial b) Coronary circulation c) Conduction d) Circulation Cardiovascular effects of inhalation anesthetics produce dose-related myodial depression of LV, RV and LA contractility as well LV diastolic

Emergence from anesthesia has cardiorespiratory, metabolic/endocrine and neurologic consequences. Awakening and extubation after anesthesia are associated with haemodynamic arousal lasting 10-25 minutes. This activation is partially mediated by elevations in catecholamine levels and partially by nociceptive stimuli. The aim of emergence after a neurosurgical procedure is to maintain intracerebral and extra-cerebral homeostasis. This implies maintenance
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

Some of the Enflurane side effects are studied below. There is a narrow margin of safety between adequate anaesthesia, unacceptable hypotension and myocardial depression. One of the enflurane side effects includes the seizure activity is rare and without sequelae. Hepatic dysfunction is rare but cross sensitization with other volatile inhalation agents possible. With prolonged anaesthesia
Desflurane muscle relaxation chemical depresses the neuromuscular junction, it decreases the force of contraction of muscles and increases fade. Endotracheal intubation is possible. There is a potentiation of nondepolarizing muscle relaxants similar to isoflurane. There have been no reports of malignant hyperthermia in man but has been seen in animals. It is advisable to avoid
Intubation contraindications can be divided into those Both Nasal and Oral lntubation and those for Nasal Intubation. Both Nasal and Oral lntubation Contraindications • Laryngeal edema. • Epiglottitis. • Laryngotracheobronchitis This is one among the important Intubation Contraindications. In these conditions the airway is already compromised giving very little place for the endotracheal Tube to
Halothane neuromuscular junction effect produces moderate muscle relaxation, it increases the degree and duration of relaxation produced by nondepolarizing muscle relax- ants. The action is at the postjunctional membrane. There is relaxation of the uterine muscle, which is useful in podalic version procedure but may hinder uterine contraction postpartum. Halothane neuromuscular junction effect may produce
The Non Rebreather Masks are the masks that do not allow rebreathing of the gases to take place when a patient is ventilated or he takes spontaneous breaths while the mask is being held. These masks of Non Rebreather type need to have a very high flow of oxygen as most of the oxygen is being lost.
