Sensory Anesthesia Achieved Through Different Paravertebral Block Approaches for Post-Op Pain Management After VATS Lung Resection
Sponsor: Centre hospitalier de l'Université de Montréal (CHUM)
Summary
Video-assisted thoracoscopic lung resection (VATS) is a minimally invasive surgical approach frequently used in the treatment of lung cancers. The most commonly used analgesic technique for this surgery is the paravertebral block with a single peroperative injection of local anesthetic. However, a recent study conducted at our institution revealed that this approach provided less relief than expected in some patients. In light of these results, it becomes crucial to distinguish between technical failures (absence of sensitive anesthesia) and the intrinsic limits of the chosen regional analgesia technique (pain originating from an unanesthetized area or pain despite the presence of sensitive anesthesia) in order to better relieve patients. This study aims to objectively assess the areas of anesthesia obtained through three methods of paravertebral block to evaluate their respective performance and optimize post-VATS analgesic management.

Interventions
Evaluation of the hypoesthesia of the thorax
In the recovery room, a member of the research team will come to assess the presence of hypoesthesia (loss of sensation) of the thorax using ice and a Von Frey filament applied at three different sections: midscapular, midaxillary and midclavicular.
