Drowning Patients..Part2..In ICU

Taking care of Drowning patient in ICU

Treat drowning victims as ARDS patients, with low tidal-volume lung-protective mechanical ventilation.
Not weaning mechanical ventilation for at least 24 hours, even if a drowning victim appears ready to extubate: the underlying pulmonary injury may result in recurrence of pulmonary edema, reintubation and increased risk of complications.
Pneumonia is usually not present initially (12% in one series) and authors believe antibiotics may be over-prescribed and sometimes harmful; instead, use clinical evidence of infection or bronchoscopic / mini-BAL sampling to identify pneumonia and need for antibiotics. Swimming pool water in particular is unlikely to cause pneumonia.
On the other hand, late-onset nosocomial pneumonias (i.e., ventilator-associated pneumonia) may be equally common among mechanically ventilated drowning victims as those with other causes of respiratory failure.
Systemic inflammatory response syndrome (SIRS) can occur after drowning — authors advise not to “misinterpret [it] as infection,” but also say that sepsis is possible, too (not helpful).
Expect a faster respiratory recovery than in typical ARDS patients, with full recovery of pulmonary function in most cases.

Anaphylaxis updates part 2- Empty Ventricle Syndrome

Patients with anaphylaxis should not suddenly sit, stand, or be placed in the upright position. Instead, they should be placed on the back with their lower extremities elevated or, if they are experiencing respiratory distress or vomiting, they should be placed in a position of comfort with their lower extremities elevated. This accomplishes 2 therapeutic goals: 1) preservation of fluid in the circulation (the central vascular compartment), an important step in managing distributive shock; and 2) prevention of the empty vena cava/empty ventricle syndrome, which can occur within seconds when patients with anaphylaxis suddenly assume or are placed in an upright position. Patients with this syndrome are at high risk for sudden death. They are unlikely to respond to epinephrine regardless of route of administration, because it does not reach the heart and therefore cannot be circulated throughout the body

Steroids In Perioperative period...The Multi-purpose Drugs

1-Steroids are not Bronchodilator ,but have well established usefulness in hyper-reactive airway. They are also said to have a permissive role for bronchodilator medication. They can be administered orally, parenterally or in aerosol form 2- Steroids have been commonly used in chemotherapy for prevention of nausea along with other anti-emetic agents . Dexamethasone was found to be highly effective when given immediately before induction rather than at the end of anesthesia . 3- Steroids do exert analgesic effects. Various routes of administration of steroids include parentral, local infiltration at operated site , as an adjuvant in nerve blocks and central-neuraxial blockade. 4 - Steroids cannot be the mainstay of therapy in anaphylaxis because of the delayed onset of action, so they are used as adjunct after initial treatment with epinephrine. 5- Steroids (Dexamethsone) are of value in reduction or prevention of cerebral edema associated with parasitic infections and neopla...
