<![CDATA[Hypotension and bradycardia are common complications following spinal anesthesia due to extensive sympathetic blockade, which can lead to hemodynamic instability and decreased perfusion of vital organs. A simple non-pharmacological preventive measure is maintaining a sitting position immediately after induction to limit the upward spread of hyperbaric anesthetic agents toward the thoracic region. This study aimed to determine the effect of maintaining a sitting position for three minutes after spinal anesthesia induction on the incidence of hypotension and bradycardia at PKU Muhammadiyah Gombong Hospital. The research employed a quasi-experimental design with a pre–post test with control group approach involving 69 respondents selected through consecutive sampling. The intervention group (n = 34) maintained a sitting position for three minutes, while the control group (n = 35) was immediately placed in a supine position. Blood pressure and heart rate were observed at 5, 10, and 15 minutes after induction, and the data were analyzed using Chi-Square and binary logistic regression tests. The results showed that the incidence of hypotension and bradycardia was significantly lower in the intervention group (p < 0.05), indicating that the sitting position acted as a protective factor. In conclusion, maintaining a sitting position for three minutes after spinal anesthesia induction effectively reduces the incidence of hypotension and bradycardia and is recommended as a simple strategy to enhance patient hemodynamic stability.]]>
