One of the lorazepam uses , is that the Lorazepam undergoes reliable absorption after oral and I.M. injection. After oral administration, maximal plasma concentrations of lorazepam occur in 2 to 4 hours and persist at therapeutic levels for up to 24 to 48 hours. The recommended oral dose of lorazepam uses preoperative medication which is […]
One may ask what is methylene blue ? Methylene blue is a water-soluble blue thiazine dye used most commonly as a treatment for methemoglobinemia or as an indicator dye. Its utility as an indicator dye has been applied to several clinical situations including identification of aspiration or placement of nasogastric tubes in critically ill patients;
Some barbiturates effects are explained here. The thiopental sodium causes profound fall in cerebral blood flow (35 to 40%) and thus ICP. Thiopentone also causes profound decrease in CMRO2. Thiopentone increases Cerebral perfusion pressure (CPP). The barbiturates effects increased the amplitudes of subcortical and early cortical components of somatosensory evoked potentials. Even full suppression of
A syrup is effective for producing sedation and anxiolysis at a Midazolam oral dose of 0.25 mg/kg with minimal effect on ventilation even when administered at doses as large as 1 mg/kg. Midazolam oral is the most commonly used oral preoperative medication for children. Midazolam oral dose which is, 0.5 mg/kg given orally 30 minutes before
Ketamine cardiovascular effects resemble sympathetic nervous system stimulation. Indeed, a direct negative cardiac inotropic effect is usually overshadowed by central sympathetic stimulation. HR and BP rise were similar between S(+)ketamine and racemic mixture. Systemic blood pressure, heart rate, cardiac output, cardiac work, and myocardial oxygen requirements all are increased after IV administration of ketamine cardiovascular
Treatment modalities in pain management play an important role when dealing with different circumstances which include the following : 1. Treatment of Disease (Cancer) in pain management : After the diagnosis and confirmation, appropriate therapy has to be started, especially for symptom ‘pain’. Symptom like mucositis, dysphagia etc, can be controlled by using local anesthetics,
Etomidate pharmacology is studied using following points. In etomidate pharmacology we find that Etomidate is a potent, direct cerebral vasoconstrictor. It decreases cerebral blood flow and CMRO2 in an independent manner. The cerebral metabolic effects of etomidate are secondary to its effect on neuronal function. As a result, previously increase ICP is lowered by etomidate
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,
Depending upon mechanism of nsaid action involved the drugs can be specifically used to achieve the desired effects. The NSAIDs have been proven to block the synthesis of prostaglandins by inhibition of the enzyme cyclo oxygenase. Cyclo-oxygenase (prostaglandin synthetase) is the enzyme involved in the cell membrane injury related destruction of phospholipids to arachidonic acid,
Ketamine produces effective sedation, hence also known as Ketamine sedation . In pediatric patients for short surgical procedures or for putting intravenous catheters before IV induction ketamine has shown effective for producing sedation. It is highly effective with a wide margin of safety, and uniquely preserves protective airway reflexes and also does not require intravenous
