Doxapram injection Doxapram is a specific respiratory stimulant. It stimulates the respiratory center preferentially and has relatively less effect on cortical and spinal sites. Following intravenous doxapram injection the drug stimulates ventilation and increases cardiac output and work. Doxapram dose It is given in a dose of 1-1.5 mg/kg by intravenous injection. Intravenous infusion can also […]
IV Anesthesia or intravenous anesthesia is when anesthesia is given through a vein through injections. Anesthesia is usually started or induced with intravenous or IV anesthesia drugs. The different IV Anesthesia drugs are: Thiopental sodium Midazolam Methohexitone Ketamine Etomidate Propofol Some Steroids Ultra short acting barbiturates The ultra-short acting barbiturates administered as IV Anesthesia to
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
The Upper Respiratory Anatomy starts with the nose, which is an essential organ for breathing and conditioning of the air. The main respiratory functions of the nose are to provide passage to the air as well as the warming and moistening of the air. The next part is the pharynx, which is further divided into
Ethyl Chloride Anesthesia is a potent anesthetic. If it has a boiling point of 12.5°C and hence is a gas at room temperature, so it is liquefied and stored under pressure in a bottle with a cap and seal. It is used as a spray. Though ethyl chloride induces anesthesia quickly, the maintenance of a steady
An important part of rapid sequence induction is Cricoid pressure was first described by Sellick in 1961, hence it is called as sellicks manoeuvre. The Cricoid pressure is used for the compession of the upper esophagus to close the aspiration of gastric contents during rapid sequence intubation. Pulmonary aspiration of gastric contents occurs usually in
Pethidine injection is a synthetic morphine like analgesic. this opioid medication has about one tenth as powerful compared to morphine. This drug has sedative and tranquilizing effects also. It may cause euphoria and sleepiness. Unlike morphine it tends to relax smooth muscles and thus relieves most types of pain associated with plain muscle spasm. But
Ether is still very rarely used in many Developing countries like India. First public demonstration of ether was given by W.T.G. Morton on I6th October 1846 for the removal of jaw tumor. Physical Properties of Ether : • It is pungent smelling liquid decomposes in presence of light, air and heat so stored in amber
The Effects of Nitrous oxide in neuroanaesthesia has been questioned many times due to its detrimental effects on the cerebral vasculature and the brain tissue. However, there are no large-scale outcome studies to approve or disapprove its continued use in neuroanaesthesia. Nitrous oxide has been used in neuroanaesthesia for many years. Intraoperative analgesia with haemodynamic
Halothane Cerebral effects include cerebral vasodilatation and increases cerebral blood flow (CBF). A concentration of I MAC doubles CBF and 1.6 MAC quadruples the CBF. Cerebral autoregulation may be abolished and cerebrospinal fluid (CSF) production reduced by 30%. The cerebral oxygen consumption (CMRO,) may be reduced by 25%. There is no epileptiform activity in the
