About the Procedure

The insertion of a pleural chest tube is often done in a setting where immediate action is required. Nonetheless, adherence to sterility, analgesia, sound technique, and safety are always warranted. Indications The most common indications for chest-tube drainage are: Pneumothorax that is recurrent, persistent, under tension, or bilateral; any pneumothorax in a patient on positive-pressure ventilation; hemothorax; recurrent or symptomatic large pleural effusion; empyema; and chylothorax. Contraindications There are relative contraindications, mainly based on hematologic abnormalities such as bleeding diatheses or coagulopathy. Blood products or coagulation factors may need to be transfused in order to reduce the . . . .

For ischemic CVA the heparin dosing is as follows: no bolus, and 600-1000 units/hr drip (not weight-based). For other indications, use the calculator below.
Heparin indication

(For ACS, strongly consider LMWH instead of unfractionated heparin. Also, if using a IIb/IIIa inhibitor with unfractionated heparin, dose the unfractionated heparin as though the patient has a STEMI.)

Note #1: Opioid analgesics have widely variable half lives, and when you switch from one form to another, you should adjust the scheduling accordingly.

Note #2: Methadone should be dosed by someone with experience using the drug. Consult palliative care or pain management.
