title: Electrolyte changes in stroke.
abstract: The present study was carried out in the department of Neurology and Medicine, Mymensingh Medical College Hospital, Bangladesh during the period of January 2009 to December 2010 to see the electrolyte changes in stroke. The serum concentration of Na⁺, K⁺, and Cl⁻ were measured in 110 cases during acute period of stroke (55 ischemic and 55 haemorrhagic strokes). Data were analyzed by computer with SPSS programme using 't' test and chi square test. In haemorrhagic stroke, out of 55 patients 29(52.72%) had abnormal sodium level, of them 23(41.8%) had hyponatremia, 6(10.9%) had hypernatremia. In contrast in ischemic stroke 23(41.80%) out of 55 had abnormal sodium level, of them 21(38%) had hyponatremia. The result showed that hyponatremia is almost equally common in both haemorrhagic and ischaemic group without significant difference (p>0.05). The study also revealed that hyponatremia is more common than hypernatremia in both groups. Mean ± SD of age of the haemorrhagic group was 60.80 ± 15.97 while the age of ischaemic group was 59.89 ± 15.84 years. Male, female ratio in haemorrhagic and ischaemic group 1:0.62 and 1:0.89 respectively. Mean ± SD of serum Na⁺, K⁺, Cl⁻ in haemorrhagic group were 136.18 ± 10.5, 3.83 ± 0.65, 97.96 ± 16.74 mmol/L, in ischaemic group 135.08 ± 9.08, 4.00 ± 0.75, 100.27 ± 8.39 mmol/L. The result showed no significant difference in haemorrhagic and ischemic stroke. Hyponatremia, hypokalamia and hyperchloredemia were more common than hypernatremia, hyperkalamia and hyperchloredemia. In haemorrhagic stroke, out of 55 patients, 21(38.18%) had abnormal potassium level, of them 19(34.55%) had hypokalemia, 2(3.63%) had hyperkalemia. In contrasts, in ischemic stroke, 15 out of 55(27.22%) had abnormal potassium level. Of them 12(21.81%) had hypokalemia and 3(5.45%) had hyperkalemia. The finding showed that hypokalemia is almost equally common in both haemorrhagic and ischaemic group without significant difference. The study also revealed that hypokalemia is more common than hyperkalemia in both groups. In haemorrhagic stroke, out of 55 patients 33(60%) had abnormal chloride level. Of them 20(36.4%) had hypochrloridemia, 13(23%) had hyperchrloridemia, in contrast, in ischemic stroke, 40 out of 55(60%) had abnormal chloride level, of them 22(40%) had hypochrloridemia and 18(32.7%) had hyperchrloridemia. The result showed that changes in chloride level after haemorrhagic and ischemic stroke are similar. The result showed hypochrloridemia is more common than hyperchrloridemia in both groups.
