DEFINITION

A decrease in blood volume will result in decreased cardiac filling, which in turn will cause reduced cardiac output and, ultimately hypotension.

MOST COMMON CAUSES

1.         Excess decrease in blood volume

            Too low dry body weight

            High UF and TMP

            Low conductivity (Low Na dialysis solution)

            Anti-hypertensive drugs therapy

            Acetate dialysis solution

            Hot dialysis fluid

            Eating food during dialysis

2.         Other causes   

            Due to cardiac failure and un-ability to increase cardiac rate

            Due to hemorrhage

CONDITIONS

1.         Applies to all Registered Nursing Personnel working in dialysis centers in Oman

2.         This procedure can be performed by a nurse undertaking nephrology / dialysis training program, provided he / she is closely supervised by an experienced dialysis nurse at all times

 

PROCEDURE

SNNursing ActionRationale
01      Keep the patient in supine position with feet slightly elevated. To maintain  sufficient blood supply to vital organs of the patient.
02    Minimize ultra filtration (UF).To prevent further hypotension.
SNNursing ActionRationale
03Reduce blood pump.  To prevent further hypotension.
04    Check blood pressure and pulse.  To assess the degree of hypotension.
05    Initiate fluid replacement as prescribed. e. g. Normal Saline. 
06    Monitor blood pressure and pulse.To monitor the patient’s condition and assess whether hypotension has been corrected or not. .
07  Start hypertonic solution if needed. e.g. dextrose AND albumin.To increase oncotic pressure. To attract fluid from extra cellular space.  
08  If the patient vomits, turn him / her to the side. Clean the vomiting and elevate slightly the patient’s head.  To prevent aspiration.  
09  Communicate with the patient and reassure him.  To allay fears and gain patient confidence and co operation
10  Monitor the condition of the patient and report progress to the treating physician.  For further management e.g. review therapy, reassess dry weight etc .  
11  Educate the patient about his / her condition and prevention of hypo tension e.g. avoid taking hypertensive drugs on the day of dialysis.  To prevent further hypotension, during dialysis and improve well-being of the patient.
12  Document patient’s condition, medication given, and response to treatment.
