RESUMO
Objective To explore the risk factors causing tetany in patients with hyperventilation syndrome. Meth?ods A total of 103 patients with hyperventilation syndrome treated in our hospital were included in this study. According to whether there was tetany, patients were divided into tetany group and non-tetany group. Values of gender, age, electrolyte, pH and p(CO2) were analysed between two groups. The factors of P0.05). It was revealed that the younger age, the lower level of the serum K+, serum phosphorus and p(CO2) were the risk factors of tetany through binary Logistic regression analysis. Conclusion The risk factors of tetany in patients with hyperventilation syndrome include younger age, lower level of serum K+and serum phosphorus and reduced p(CO2).
