Propofol anesthesia has become the induction drug of choice for most of the surgical procedures, especially when rapid and complete awakening is desirable. Continuous IV infusion of Propofol anesthesia with or without other anesthetic drugs, is commonly used in TIVA and for sedation. Due to its quick onset and offset characteristics it is also becoming […]
The sedative midazolam side effects and fluctuations in vital signs were the most frequent findings following parenteral administration of midazolam injection. These are affected by the lightening or deepening of anesthesia, instrumentation, intubation and use of concomitant drugs. The more frequently encountered fluctuations in vital signs of midazolam side effects included decreased tidal volume and/or
Hypoxia mechanism Following phases are included in the Hypoxia mechanism : 1. Anoxic hypoxia—Gas phase. There is inadequate supply of oxygen to the lungs, or the lung is not functioning properly. 2. Anemic hypoxia—Fluid hypoxia (phase). There is a decrease in the oxygen carrying capacity of the blood. 3. Stagnant hypoxia—Fluid phase. There is decreases
Physiotherapy management electrotherapy is the application of electrical current to the area of generation of nociception. Physiotherapeutic methods are based on use of mainly two different modalities: 1. Electrotherapy 2. Exercise therapy This can be achieved with following methods of electrical current: • Low frequency • Medium frequency • High frequency Low frequency: i) The
Midazolam effects cerebral metabolic oxygen requirement (CMRO2) by decreasing it and cerebral blood flow, analogous to barbiturates and propofol. It causes dose-related changes in regional cerebral blood flow in brain regions associated with the normal functioning of arousal, attention, and memory. Patients with decreased intracranial compliance show little or no change in intra-cranial pressure when
Aging and liver disease affect glucuronidation less than oxidative metabolic pathways. And thus, lorazepam, oxazepam, benzodiazepines in the elderly and temazepam are preferentially used in elderly patients over other benzodiazepines as they are metabolized only by glucuronidation and have no active metabolites. Elderly patients may also be intrinsically sensitive to benzodiazepines, suggesting that the enhanced
From time immemorial mankind has been aware of opium classification . The word opium itself is derived from Greek word for juice. Arabian traders popularized it and introduced it to Europe. Paracelsus (1493—1541) reintroduced it and made it popular. It was at one time considered as “God’s own medicine” and used in various remedies from
The most significant Methodone feature is its exactly identical pharmacodynamics and methodone mechanism of action as that of morphine in equipotent (equianalgesic) doses. Methodone is an agonist with diphenyl structure (2 phenyl rings at the center). The psychological behaviour of methadone addiction is not as markedly abnormal as that of other pure agonists like heroin,
The drugs remain the main modality to achieve pharmacological management of pain . Various routes of administration for various drugs have been employed. The quest for an ideal, suitable analgesic continues. Conventionally three classes of drugs are employed to achieve various degrees of analgesia in pharmacological management of pain : 1. Opioids: For a long time
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
