Intubation contraindications can be divided into those Both Nasal and Oral lntubation and those for Nasal Intubation. Both Nasal and Oral lntubation Contraindications • Laryngeal edema. • Epiglottitis. • Laryngotracheobronchitis This is one among the important Intubation Contraindications. In these conditions the airway is already compromised giving very little place for the endotracheal Tube to […]
Many common critical care drugs are among the safe drugs during pregnancy, whereas some should be used with caution and others avoided entirely. When treating pregnant patients, it is the physician’s responsibility to treat the mother as the primary patient. Fetal considerations are secondary to ensuring maternal well-being because maternal demise will generally result in
What is Morphine sulphate Morphine sulphate injection is an opium alkaloid and a standard potent opioid analgesic. This opioid acts as an anxiolytic, hypnotic and sedative. It causes both the stimulation and the depression of the central nervous system. The depression caused by morphine leads to analgesia, respiratory depression, depression of cough reflex and sleep
Neuroleptanalgesia Neuroleptanalgesia is method of IV anesthesia which combines at neuroleptic drug with opioid analgesic drug. The most favored combination is neuroleptic droperidol and the analgesic fentanyl. The combination used neuroleptanalgesia induces state which is different from usual general anesthesia. Because the patient is awake during surgery and is cooperative during the operative and surgical
Capnography is the continuous measurement of end tidal carbon dioxide (ETCO2) and its waveform. The normal recording from a Capnography is between 32 to 42 mmHg (3 to 4 mmHg less than arterial pCO2 which is 35 to 45 mmHg). Capnography works on the principle that infrared light is absorbed by carbon dioxide. And this
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
McNarry and Goldhill compared ACDU Scale (Alert, Confused, Drowsy, Unresponsive) and AVPU scale (Alert, responds to Voice, responds to Pain, Unresponsive) by the American college of surgeons with GCS scale for neurological assessment of critically ill ward patients. Just like GCS the ACDS Scale is a method to assess the neurological status and level of
What is Nitrous oxide gas ? Nitrous oxide gas is a Gaseous Anesthetic agent. Nitrous oxide gas is a colorless, inorganic gas with a sweet taste. The oxygen in the nitrous oxide molecule is not available for tissue respiration as nitrous oxide does not undergo significant decomposition in the body. Nitrous oxide gas, if administered
Sevoflurane Inhalation anesthetic was synthesized by Baxter Laboratories (1960) but introduced into clinical practice in Japan in 1990, now widely used the world over. Unlike isoflurane it does not exist as an optical isomer, it does not have an asymmetric atom. It contains only fluorine atoms, so it does not affect the ozone layer in
A common question that arises while studying respiratory physiology is what is minute ventilation and minute volume. The minute ventilation is the amount of air a person breaths in a minute. The minute ventilation is calculated by the multiplication of the tidal volume and the respiratory rate. What is minute ventilation? The normal tidal volume
