RESUMO
Perioperative management of deaf and dumb patients can be a challenging task. For smooth postoperative recovery, proper care should begin in the preoperative period. Understanding the patients’ needs and training him to follow the instructions requires to involve a communication specialist. Judicious use of sedatives and analgesics is essential to keep the patient pain‑free and comfortable. Postoperatively, the patient should be kept awake, enough to understand the internal need of the body and to make a meaningful response to external stimuli. Adequate preoperative planning and coordinated team efforts with involvement of specialists can help in delivering better postoperative care.
RESUMO
Nicorandil is a commonly used antianginal agent, which has both nitrate‑like and ATP‑sensitive potassium (KATP) channel activator properties. Activation of potassium channels by nicorandil causes expulsion of potassium ions into the extracellular space leading to membrane hyperpolarization, closure of voltage‑gated calcium channels and finally vasodilatation. However, on the other hand, being an activator of KATP channel, it can expel K+ ions out of the cells and can cause hyperkalemia. Here, we report a case of nicorandil induced hyperkalemia unresponsive to medical treatment in a patient with diabetic nephropathy.

Immune thrombocytopenic purpura (ITP) patients are at high-risk for bleeding complications during and after cardiac surgeries involving cardiopulmonary bypass. We report a patient with ITP with severe coronary artery disease and mitral valve regurgitation who underwent uncomplicated coronary artery bypass grafting and mitral valve replacement. Three weeks later, the patient was readmitted in a very low general condition with signs of pericardial tamponade. We describe our experience of managing the case.
