Background and aims We report here the use of bilateral multiple level injections ultrasound-guided TPVB combined with sedation as a sole anesthesia technique for critical ill patient (ASA IVE) undergoing pericardial drainage by lower midline chest incision. Hemodynamic instability is the major concern in surgical patients with pericardial diseases. In addition our patient has CHF (NYHA3), AFib and right side pnemothorax. Anesthesia in such patients requires special attention because of low cardiac capacity and respiratory function. Effectively blocking pain pathways is important to control the heart rate and prevent postoperative respiratory compromise. The aim was to avoid general anesthesia by providing bilateral TPVB without any complications.
Methods We planned to perform bilateral multiple level injections ultrasound-guided TPVB at level of T6 and T7. Using transversal technique at the articular process view in-plane for one side and the sagittal technique at the transverse process view in-plane for the other side. The proper placement of the needle in the paravertebral space was confirmed with hydrolocation then 0.25% Ropivacaine 10 ml injected after negative aspiration of blood or air. Total amount: 40 ml of 0.25% Ropivacaine (10 ml each injection). Sedation: Dexmedetomidine.
Results No complications occurred. At the end of surgery the patient was comfortable, free of pain until postoperative day 2 (pain score 2–3/10) and discharged home after 24 days without any complications.
Conclusions For patients with limited cardiac reserve due to pericardial effusion, bilateral TPVB as the sole anesthesia technique should be strongly considered for performing surgical pericardial drainage when general anesthesia is not desirable and this could be a new indication for bilateral TPVB.
