If you suffer from low blood pressure, you know how difficult its management is. Nausea, fatigue, dizziness, blurred vision are few of the many problems that you have to take care of. Adding salt to injury, a new study claims that if your blood pressure is low, your death risk increases on the operation table. According to a study presented at Euroanaesthesia 2015, the European Anaesthesiology Congress, in Berlin, Germany, low blood pressure before a surgery put you at an increased risk of death during or after the surgery when compared with those who have a high blood pressure before the surgery.
How was the study conducted?
Data from 252,278 patients was studied. Different models with varying complexities were used to analyse 29 perioperative (post, intra and pre ) risk factors like age, gender, race, co-morbidities, medications, and surgical risk score.
What did the study find?
It was found that high blood pressure was not associated with post-surgery mortality but, pre operative low blood pressure was associated with increased risk of peri-operative mortality. It was found that patients with systolic blood pressure below 100 mm Hg,the death risk increased by 40%. Patients with a diastolic BP of under 40 mmHg the death risk increased by 2.5 times. However, patients with BP values of 100/40 or lower were at the greatest death risk.
The researchers believed that low blood pressure is often under recognised as risk factor of death during surgery and more studies should search for ways to reduce a patient's death risk.
