P otassium P otassium How to replace that most simply? - By full or half strength Darrow solution - By full or half strength Darrow solution - Every second bottle.... after the deficit - Every second bottle.... after the deficit

Still about Resuscitation How do you know you give enough iv fluids? How do you know you give enough iv fluids? - if he is passing urine - if he is passing urine How much urine before going to theatre? How much urine before going to theatre? - at least cc/hr - at least cc/hr - ideally ? 150 cc - ideally ? 150 cc Maintenance iv fluid: Maintenance iv fluid: - at least 3 liters iv daily (1 l saline, 2 dextrose) - at least 3 liters iv daily (1 l saline, 2 dextrose) fluid loss: skin: 1000 cc, lungs: 500 cc, urine: 1500cc fluid loss: skin: 1000 cc, lungs: 500 cc, urine: 1500cc Make sure: urine production 3 p.o. day: at least 1500cc Make sure: urine production 3 p.o. day: at least 1500cc

Decided: operation is needed To transfer or not to transfer ? General rule: General rule: Transfer for operation, but after resuscitation! Transfer for operation, but after resuscitation! If you can’t transfer do a laparotomy If you can’t transfer do a laparotomy Inform patient Inform patient

No…… I want to have a CO as my surgeon who attended the training in Malawi………

Remember.....what is the most likely diagnose of BOWEL Obstruction?
