Current studies

• Pain in the PACU: Comparison of pain management methods in the PACU and determination of a limit for analgesic administration.

Proper treatment of postoperative pain is only possible if the patient's pain experience is correctly assessed.
The purpose of this study is to identify the correlation between three measurement methods after waking up from anaesthesia and to determine the threshold for the administration of mild or powerful pain medications. This could help optimise postoperative pain management in the future.

• Diep-Flap Effect of phenylephrine versus norepinephrine on venous return with a DIEP flap

The primary objective of the study is to evaluate the effect of two different medications that raise blood pressure (phenylephrine vs. norepinephrine) on the return flow of blood to the heart. These are two medications that have been used routinely for decades, and are also used daily
for many of the patients in our hospital.

• SAPB Serratus Anterior Plane Block for Minimally Invasive Cardiac Surgery

The purpose of the study is to assess the analgesic effect of an Anterior Serratus block in minimally invasive cardiosurgical procedures as compared to a control group.

• Circumcision: Comparison of caudal blockade and dorsal penile nerve block in adjunct with dexamethasone for analgaesia after paediatric male circumcision: a single-centre randomised-controlled trial

The objective of this study is to determine whether dexamethasone prolongs the duration of the analgaesic effect in a penile block, as it does in a caudal block, in circumcisions.

• Vivalink: A feasibility study of the cardiac ECG monitor from Vivalink and analysis of ECG signals by open-source algorithms for EWS calculations.

Examining whether the Vivalink Cardiac ECG patch and the Movesense patch are able to measure vital parameters correctly and continuously and can be deployed to calculate an 'early warning score' more easily and continuously. The records of both devices will be compared with the standard vital parameters measured and recorded in intensive care.
This comparison will be performed by combining the registrations of both devices with open-source computer algorithms. This may allow a faster response to deteriorating patients in the future.

• Cogenius study: A comparison of conventional and cooled radiofrequency treatment of the genicular nerves versus sham procedure for patients who have chronic knee pain: a multi-centre, double blind and randomised controlled trial

To research the effect of both chilled and conventional (classical) radiofrequency (RF) treatment on individuals who have chronic knee pain and for whom conservative treatments have failed. The effect of this treatment will be compared with a sham procedure in terms of knee pain, knee function, quality of life, mental health and overall health care. Patients suffering from chronic knee pain caused by osteoarthrosis or persistent pain after a total knee replacement placement are eligible to participate and will be followed up for approximately two years as part of this study.

• XEOS: High-resolution specimen PET-CT imaging for the perioperative visualisation of resection margins: an exploratory pilot study

SQuaD 4 Anaesthesia will provide support for the practical implementation of this study and the data collection.

Acquire scientific knowledge on the clinical utility and radiation safety of perioperative high-resolution PET-CT specimen imaging (Xeos Medical) for various indications. Several disciplines including gynaecology, urology, general surgery, dermatology, nuclear medicine and anatomopathology are involved in this study.

• Avalus European Registry: Real-world results of aortic valve replacement with the AVALUS pericardial bioprosthesis

SQuaD 4 Anaesthesia will provide support for the practical implementation of this study and the data collection.

This study aims to research the outcome of aortic valve replacement with the AVALUS pericardial biological heart valve. This heart valve is also frequently used at Maria Middelares General Hospital for aortic valve replacements. This study will examine how patients fare up to one year post surgery. This is an observational study, with no additional interventions or examinations.

• APPIRED III: Alkaline Phosphatase (RESCAP) for the prevention of perioperative and post-surgical complications after cardiac surgery.

This study aims to determine whether RESCAP can reduce the incidence of kidney-related complications after cardiothoracic surgery.
This study will include high-risk patients undergoing cardiothoracic surgery who require the use of the heart-lung machine.

• Ready 1 A phase 3, randomised, double-blind, active and placebo-controlled study on the use of CUSA-081 for dysfunctional central venous catheters.

The purpose of this study is to demonstrate that the product under investigation, CUSA-081, works better than a placebo for restoring function of a blocked central venous catheter.
