Broadly chronic pain syndrome type can be classified on the basis of aetiopathological origin of the syndrome of chronic pain. The advantage of using this classification is that while deciding the modality of control and management it becomes simpler to choose specific plan of management. 1. Non-oncogenic chronic pain: Chronic pain commonly seen in skeletal […]
Some of the Ketamine effects discussed here. Ketamine does not increase the intraocular pressure (lOP) in routine analgesic doses. Even after the IM injection of 8 mg/kg, ketamine doses not raise lOP. However, in an: other study, in children anaesthetized with halothane, ketamine demonstrated a dose-dependent effect on lOP. A dose of 6 mg/kg IM
Ketamine respiratory depression is considered to be the ideal anesthetic for asthmatic patients because it decreases the risk of bronchospasm during induction of anesthesia and preserves the pulmonary vasoconstriction reflex to hypoxia. It does not produce significant depression of ventilation. The ventilatory response to carbon dioxide is maintained during ketamine respiratory depression anesthesia. The respiratory
Ketamine is associated with psychedelic effects and dependence. Well the question here arises is that Is Ketamine addictive ? These effects are dose-related and comprised of multimodal hallucinatory experiences, a sense of slowing, paranoid ideation and enhancement of sexual, musical and sensory enjoyment. The mechanisms of these phenomena are largely due to its complex multi-receptors
The ideal neuromuscular blocker drugs (NMB) would be rapid in onset, have a predictable offset, be nontoxic, lack deleterious cardiovascular or autonomic effects, undergo a defined means of metabolism and excretion preferably independent of end-organ function, and be inexpensive. Many of these characteristics are found in clinically available drugs like cisatracurium. To briefly review, neuromuscular
Effects of Barbiturates on the body are listed here. Thiopentone decreases the tidal volume and the effect on respiratory rate is biphasic ranging from tachypnea during light anesthesia to a progressive slowing of respiration with deepening anesthesia. However, like propofol, functional residual capacity is not reduced by thiopentone. Effects of Barbiturates on the body administered
The fact that total body clearance of propofol metabolism exceeds hepatic blood flow is consistent with extra hepatic clearance. Indeed hepatic clearance of propofol was approximately 60% of total body clearance.Pulmonary uptake of propofol is significant and influences the initial availability of propofol. Human lungs take part in the elimination of propofol by transforming the
Incidences of anaphylaxis have been reported after induction with thiopental. The incidence of barbiturate allergy is estimated to be 1 per 30,000 patients. The majority of the patients who suffer from anaphylaxis due to barbiturate allergy also possess history of chronic allergy. Barbiturate Allergic reactions include urticaria, angioneurotic edema, other skin reactions, agranulocytosis and thrombocytopenic
For sedation prior to anesthesia or procedures, for longer and/or more stimulating procedures, midazolam IM can be used to facilitate insertion of an IV catheter for titration of additional medication. Midazolam IM doses of 0.1 to 0.15 mg/kg are usually effective and do not prolong emergence from general anesthesia. For more anxious patients, doses up
Pentazocine agonist antagonist is supposedly capable of producing spinal level analgesia. However, it produces significant sedation, drowsiness. The drugs which are equidistant to either pure agonists or pure antagonists in the terms of their activity belong to this group, agonists at one receptor and antagonists at another. Two groups of synthetic compounds belong to this
