It appears that hypokalaemia
can be caused by excessive consumption of three of the most common ingredients in cola drinks - glucose, fructose and caffeine.
This reduces the risk of renal toxicity and hypokalaemia
, both side-effects of amphotericin B.
Additionally, urinary potassium had to exceed 100 mmol in 24 hours or to be within normal limits to confirm the diagnoses of antibiotic-induced renal loss of potassium or hypokalaemia
from beta-2-agonists respectively.
Patients were labelled as having hyponatraemia, hypokalaemia
, both or having normal serum sodium and potassium levels.
We were concerned that hypokalaemia
contributed to mortality, and explained the unpredicted deaths.
Laboratory studies revealed normal WBC and platelet, low Hb (microcytic hypochromic anaemia), hypokalaemia
due to diarrhoea, hypoalbuminemia, low iron and ferritin.
10) As diuresis sets in with the recovery phase, the risk of hypokalaemia
Even though patients with circulatory or metabolic disturbances such as shock, hyponatraemia or hypokalaemia
were more likely to have been tested for HIV, there was no significant difference between HIV-infected and uninfected children in respect of these metabolic parameters on admission.
Our study also confirmed the earlier autopsy results of septicaemia, hypoglycaemia, and hypokalaemia
as being the immediate causes of death (2).
These patients are particularly at risk of hypokalaemia
as a result of their poor intake and increased losses due to diuretic use and faecal or catabolic losses.
Serum magnesium monitoring may have prognostic and perhaps therapeutic implications, because critically ill patients are predisposed to both symptomatic and asymptomatic magnesium deficiency that can lead to some important clinical consequences (such as hypokalaemia
, cardiac arrhythmias, hypocalcaemia, neurotoxicity and psychiatric problems], ultimately increasing the morbidity and mortality.
Laboratory abnormalities include hyposthenuria, hyponatraemia, hypokalaemia
, and hypochloraemic metabolic alkalosis associated with increased urinary loss of sodium, potassium, chloride and calcium.
In the realm of the 'metabolic' myopathies, it is important to rule out hypokalaemia
, hypo- and hyper-calcaemia, osteomalacia and Cushing's syndrome.
Insulin therapy used to reverse DKA may trigger abrupt, severe and life-threatening hypokalaemia
as potassium is taken back up into the cells.
Correlation between severity of SAH and QTc and QTc extension is reported to be dependent on the formula used (19), while the female gender and hypokalaemia
are also independent risk factors for extension of the QTc interval (9,21).
