Hiccups after brain hemorrhage surgery are mainly due to phrenic nerve involvement after brain hemorrhage, and hiccups can occur after surgery in the following ways: 1. If a patient with brain hemorrhage is conscious and can cooperate, you can ask the patient to hold his breath before breathing, which can briefly block phrenic nerve involvement and stop the hiccups. 2. If the hiccups are not relieved by the above treatment, the patient can be given haloperidol, which can also treat the hiccups.
