Hypertensive intracerebral hemorrhage is a common condition in clinic. Due to the improvement of minimally invasive technology, its therapeutic effect is good, but there are still postoperative complications. The corresponding routine nursing intervention is not effective in the rehabilitation of postoperative patients with hypertensive intracerebral hemorrhage. In this paper, cluster nursing was applied to the treatment of postoperative patients with hypertensive intracerebral hemorrhage. For this purpose, a retrospective study or experiment was conducted on 150 patients with hypertensive intracerebral hemorrhage in the hospital specifically from January 2019 to December 2020. According to the nursing strategy, patients were divided into experimental (n = 75) and control groups (n = 75), respectively. The control group adopted routine nursing mode, whereas the experimental group adopted cluster nursing mode. The treatment compliance of patients in the experimental group was 86.67%, while that in the control group was 73.33% ( P  < 0.05). The total incidence of postoperative complications in the experimental group was 3.2%, which was lower than 25% in the control group ( P  < 0.05). The motor function score of the experimental group was better than that of the control group ( P  < 0.05). The application of cluster nursing in postoperative patients with hypertensive intracerebral hemorrhage is feasible, and its nursing effect is significant, which can not only reduce the incidence of postoperative complications but also improve patients’ compliance and quality of life. It has good application value.
