The Non Rebreather Masks are the masks that do not allow rebreathing of the gases to take place when a patient is ventilated or he takes spontaneous breaths while the mask is being held. These masks of Non Rebreather type need to have a very high flow of oxygen as most of the oxygen is being lost. […]
A rapid Isoflurane inhalation induction is possible with isoflurane because of low blood/gas solubility coefficient. It has a pungent odour, patients complain of burning sensation in the airway though there is no increase in airway reflexes or secretions. So a smoother induction is seen with halothane or sevoflurane which are preferred for inhalational induction. Recovery:
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
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
Clinical studies using this strategy have claimed that even Normal Cerebral Perfusion Pressure values as low as 50 mm Hg are well tolerated with 8% mortality, and good recovery at 6 months after injury with little or moderate disability in 80% of patients. An increase in MAP may increase brain oedema. Therefore, lower intravascular pressures
Chronic pain is a persistent condition that affects millions of people worldwide. It can be debilitating and significantly impact a person’s quality of life. Fortunately, there are various strategies and approaches available to help manage chronic pain effectively. In this article, we will explore some of the commonly used chronic pain management strategies. 1. Medication:

In Isoflurane cardiac function , the effect is that the cardiac output is maintained due to the slight increase in heart rate reflexly due to hypotension. There is a dose-dependent decrease in arterial pressure due to peripheral vasodilatation and myocardial depression, less than that due to halothane. There is a selective coronary vasodilatation and decrease
Some disadvantages of volatile anesthetics are listed here. • Poor oxygen availability is one of the disadvantages of volatile anesthetics ; hypoxic insults are poorly tolerated due to dilution of air-oxygen mixture by ethe’ vapour. • Patient breathes dry air because water vapour in the air condenses on the mask due to low temperature because
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
Cerebral Aneurysm Clipping is one of the important modalities for the treatment of aneuryms apart from coiling so the anesthetic management of such cases is as follows. Skull is a fixed vault and most intracerebral structures are relatively in compressible, hence even a small haemorrhage can result in a significant anatomic distortion producing significant rise in ICP
