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.

About this study

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.

  • known hypertensive patients.

Treatment and study plan

Primary outcomes

  1. Incidence of surgery canceled due to high blood pressure figures in the operating room.

    Time frame: 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

Secondary outcomes

  1. Score d'anxiété: Amsterdam Preoperative Anxiety and Information Scale (APAIS)

    Time frame: before entering the operating room

    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

  2. The quality of reception in the operating room

    Time frame: before entering the operating room

    Patient satisfaction: Bad/average/good

  3. History of cancellation for hypertension in the operating room

    Time frame: Pre-operative, at the anesthesia consultation

    presence or absence of a history of cancellation for high blood pressure figures

  4. specify the anti-hypertension molecule

    Time frame: Pre-operative, at the anesthesia consultation

    the antihypertensive molecule taken by the patient as background treatment

  5. Control and monitoring of hypertension Control and monitoring of hypertension Control and monitoring of hypertension

    Time frame: During the pre-anesthesia consultation

    The patient is followed-up in town: by a general practitioner or a cardiologist

  6. Entrance to the operating room: on foot, chair or trolley

    Time frame: before entering the operating room

    Arrival at the operating room: on foot, chair or trolley

  7. Day of the week

    Time frame: before entering the operating room

    Day of the week: from Monday to Saturday

  8. Waiting time before entering the operating room (in minutes)

    Time frame: before entering the operating room

    waiting time before entering the operating room: in minutes
