PLEURAL FLUID ASPIRATION INDICATIONS •DIAGNOSTIC • LARGE PLEURAL EFFUSION • CARDIO RESPIRATORY EMBARASSMENT • INFECTED PLEURAL FLUID • ACUTE PULMONARY EDEMA • PERSISTENT PLEURAL EFFUSION INSPITE OF ANTI TUBERCULOUS TREATMENT . CONTRAINDICATIONS • Local infection over proposed site of thoracentesis (e.g. cellulitis, herpes zoster). Select another entry site . • Uncontrolled bleeding ,Coagulopathy is a relative contraindication. • Caution must be exerted when performing thoracentesis in mechanically ventilated patients. The positive pressure of the ventilator may expand the lung to greater than normal volumes, increasing the potential risk of pneumothorax. Ultrasound- guided thoracentesis is recommended in this situation • Defer thoracentesis in patients with severe hemodynamic or respiratory compromise until the underlying condition is stabilized
- 22. PROCEDURE • POSITION :patient sit up against a back rest or leans forward resting the arms on the tip of a bed table. • SITE : 7th or 8th intercostal space in midaxillary or scapular line .The part is prepared with cetavlon or iodine and spirit . • LOCAL ANAESTHETIC : skin , subcutaneous tissue and parietal pleura are infiltrated with 2% lignocaine . • PUNCTURE: The aspiration needle is introduced at right angles to the skin , midway between two rib near the upper border of lower rib and advanced till pleura is ruptured whih is indicated by GIVE IN . • The needle is now attached with 50 ml syringe and two way stop cork and about 500-1000ml of fluid is removed at a time. Aspiration must be stopped if patient coughs .

- 30. CARDIOPULMONARY RESUSCITATION) Cardio pulmonaryresuscitation (CPR) is a technique of basic life support for the purpose of oxygenation to the heart, lungs and brain until and unless the appropriate medical treatment can come and restore the normal cardiopulmonary function. BASIC STEPS OF CAB • C-COMPRESSION • A-AIRWAY • B-BREATHING
- 31. CHEST COMPRESSION TECHNIQUE • Thepalm of one hand is placed in the concavity of the lower half of the sternum 2 fingers above the xiphoid process. (AVOID xiphisternal junction → fracture & injury). The other hand is placed over the hand on the sternum. • Shoulders should be positioned directly over the hands with the elbows locked straight and arms extended. Use your upper body weight to compress. • Sternum must be depressed atleast 5 cm in adults, and 2-4 cm in children, 1- 2 cm in infants . • Must be performed at a rate of 100- 120/min • During CPR the ratio of chest compressions to ventilation should be as follows: • Single rescuer = 30:2 • In the presence of 2 rescuers chest compressions must not be interrupted for ventilation
