The Phenobarbital schedule is listed here. The long-term administration of high doses of thiopental is associated with an increased incidence of nosocomial infections and associated mortality. Barbiturate coma may cause reversible leucopenia and an increased infection rate. Long-term administration of thiopental may also promote reversible antibiotic-induced bone marrow suppression. Thiopentone depresses T-lymphocyte function. Loop et […]
The management of methods of pain relief is and will always remain a challenging task for the clinicians. Many a times in spite of understanding the pathophysiology of pain, it becomes extremely difficult to control that pain. Most of the times the pathophysiology itself, may be shrouded in the mist of uncertain methods of pain
Several effects of ketamine are discussed here. Ketamine can attenuate important pro-inflammatory key functions of neutrophils in vitro, by inhibiting activated neutrophils, although these inhibitory effects are similar for racemic ketamine and its isomers. Thus ketamine might have role in limiting tissue injury in sepsis or ischemia/reperfusion. In the patients with sepsis caused by gram-negative
Propofol and egg allergy are quietly related as one of the side effects. Allergic reactions to propofol on first exposure are usually because of the isopropyl groups that may act as epitopes and that are present in various medications andcosmetics. Allergic reactions to propofol upon re-exposure are usually because of the phenol molecule. Propofol and
Cause of hypoxia Common cause of hypoxia and Cyanosis are : 1. Factors present before the operation • Oedema of glottis • Ludwig’s angina • Bilateral quinsy 2. Carcinoma of larynx 3. Tracheal compression and stenosis due to any cause 4. Foreign body in bronchus 5. Carcinoma of bronchus 6. Acute or chronic bronchial asthma
Propofol exhibits dose-dependent effects on memory. Infusions of propofol amnesia for conscious sedation produce concentrations below those required for consistent amnesia. In the study by Matsuki et al. Propofol and midazolam did not differ in amnesic effects to non-invasive stimuli. However, for invasive stimuli, midazolam showed a stronger amnesic effect at the moderate sedation level,
There is an ongoing debate as to whether propofol EEG exhibits pro- or anticoagulant effects, and whether it should be used in patients with epilepsy. In a prospective study, Meyer et al documented propofol EEG as a sedative-hypnotic agent with anticonvulsant properties as shown by depression of spike-wave patterns in children with epilepsy and by
The effect of agonist drug of opoid group have a lot of impact as listed: Cough: The cough center in medulla is suppressed, leading to antitussive action. Pure agonists especially related with codeine have pronounced effect. Nausea and Vomiting: The emesis is usually due to direct stimulation of chemoreceptor trigger zone (CTZ) of area postrema of the
The etomidate pharmacokinetics is altered in the elderly, with a decrease in initial distribution volume and clearance (a decrease of 2 mL/min/kg every decade). Compared to normal patients, the cirrhotic patients have normal clearance rates, suggesting that cirrhotic patients metabolize etomidate normally, but the distribution volume and elimination half-life were twice as great. A 30%
The action of Opoid crisis on hypothalamic nuclei also may be involved in producing slight fall in the body temperature. Modulation of pain through diencephalic areas like periaqueductal grey, thalamic center and hypothalamic areas is produced. The mid-brain (Mesencephalon) basal nuclei, especially due to excitation of parasympathetic region of Edinger Westphal nucleus of the oculomotor nerve
