Hypertension as a Reason for Concellation of Elective Minor Abdominal Surgery

During the anesthesia outpatient consultation, patients proposed for minor abdominal surgery, known hypertensive patients are selected.

On the day of the procedure, we check the blood pressure figures. If the numbers are high: SBP ≥ 180 and/or PAD≥110: we start by a filling as well as a dose of 1 mg Midazolam IV and the blood pressure figures are re-evaluated. If 3 measurements blood pressure figures remain above the threshold values: Surgery is postponed and the patient will be included to group (A) for canceled. If the blood pressure figures are correct, the surgery is accepted and the patient will be included in the group (NA) for not canceled.

Study Overview

• Status: Completed
• Conditions: Surgery; Hypertension Secondary

Detailed Description

During the anesthesia outpatient consultation, patients proposed for minor abdominal surgery, known hypertensive patients are selected. If the blood pressure figures are balanced in the previous 12 months, they are included in the study and the anesthesiologist informs them of the study protocol and obtains their consent.

On the day of the procedure, the patient is admitted to the operating room. We begin warming the patient and carry out standard monitoring, then, we check the blood pressure figures. If the numbers are high: SBP ≥ 180 and/or PAD≥110: we start by a filling as well as a dose of 1 mg Midazolam IV and the blood pressure figures are re-evaluated. If 3 measurements blood pressure figures remain above the threshold values: Surgery is postponed and the patient will be included to group (A) for canceled. If the blood pressure figures are correct, the surgery is accepted and the patient will be included in the group (NA) for not canceled.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Incidence of surgery canceled due to high blood pressure figures in the operating room.	In the operating room, if the blood pressure figures are high(according to BHS recommendations from 2016) the surgery is canceled	In the operating room

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Score d'anxiété: Amsterdam Preoperative Anxiety and Information Scale (APAIS)	The APAIS scale is presented in the form of a questionnaire composed of six questions, the first three of which assess the patient's anxiety relating to anesthesia, the following two assess the patient's anxiety relating to surgery, and finally a last question assesses the patient's desire for information. The minimum score is 6 and the maximum is 20. If the score is greater than 11, this means that the patient's level of anxiety is high	before entering the operating room
The quality of reception in the operating room	Patient satisfaction: Bad/average/good	before entering the operating room
History of cancellation for hypertension in the operating room	presence or absence of a history of cancellation for high blood pressure figures	Pre-operative, at the anesthesia consultation
specify the anti-hypertension molecule	the antihypertensive molecule taken by the patient as background treatment	Pre-operative, at the anesthesia consultation
Control and monitoring of hypertension Control and monitoring of hypertension Control and monitoring of hypertension	The patient is followed-up in town: by a general practitioner or a cardiologist	During the pre-anesthesia consultation
Entrance to the operating room: on foot, chair or trolley	Arrival at the operating room: on foot, chair or trolley	before entering the operating room
Day of the week	Day of the week: from Monday to Saturday	before entering the operating room
Waiting time before entering the operating room (in minutes)	waiting time before entering the operating room: in minutes	before entering the operating room
