Carotid endarterectomy (CEA) surgery is generally performed for patients who under the risk of ischemic cerebral stroke due to the critical obstruction of the carotid artery. Ischemic complications may occur during the surgery. So, the awakeness of the patient is very important during the surgery. Regional anesthesia techniques may be performed instead of general anesthesia for shunt placement during CEA surgery. Herein, we aimed to share our successful US-guided carotid sheath block experience for anesthesia management during CEA surgery.
Abstract Background Quadratus lumborum block (QLB) is a fascial plane block. There is no randomized study on the efficacy of QLB for lumbar surgery. We evaluated the efficacy of QLB for postoperative pain management and patient satisfaction after lumbar disc herniation surgery (LDHS). Methods Sixty patients with ASA score I-II planned for LDHS under general anesthesia were included. We allocated the patients into two groups: the QLB group ( n = 30) or the control group ( n = 30). QLB was performed with 30 ml 0.25% bupivacaine in the QLB group. Paracetamol 1 g IV 3 × 1 was ordered to the patients at the postoperative period. If the NRS score was ≥ 4, 1 mg/ kg tramadol IV was administered as rescue analgesia. Results There was a reduction in the median static NRS at 0 h and 2 h with QLB compared to the control group ( p < 0.05). There was no difference in the resting NRS at any other time point up to 24 h. The median dynamic NRS was significantly lower at 0, 2, 4, 8, and 16 h in the QLB group ( p < 0.05). The need for rescue analgesia was significantly lower in the QLB group. The incidence of nausea was significantly higher in the control group. The postoperative patient satisfaction was significantly higher in the QLB group ( p < 0.05). Conclusion We found that the QLB is effective for pain control following LDHS.
Thoracic paravertebral block can provide analgesia for unilateral chest surgery and is associated with a low complication rate. Horner syndrome also referred to as oculosympathetic paresis, is a classic neurologic constellation of ipsilateral blepharoptosis, pupillary miosis, and facial anhidrosis resulting from disruption of the sympathetic pathway supplying the head, eye, and neck. We present a patient with an ipsilateral transient Horner syndrome after ultrasound guided single shot of 15 mL 0.25% levobupivacaine for thoracic paravertebral block at T5–6 level. It should be kept in mind that even a successful ultrasound guided single shot thoracic paravertebral block can be complicated with Horner syndrome due to unpredictable distribution of the local anesthetic. O bloqueio paravertebral torácico pode proporcionar analgesia para cirurgia torácica unilateral e está associado a um baixo índice de complicações. A síndrome de Horner (também denominada paralisia oculossimpática) é uma constelação neurológica clássica de blefaroptose ipsilateral, miose pupilar e anidrose facial devido a distúrbio da via simpática que fornece inervação para a cabeça, olhos e pescoço. Apresentamos o caso de um paciente com síndrome de Horner transitória ipsilateral após a administração de injeção única de 15 mL de levobupivacaína a 0,25% para bloqueio paravertebral torácico ao nível de T5-6 guiado por ultrassom. Devemos considerar que mesmo um bloqueio paravertebral torácico bem-sucedido com a administração de injeção única e guiado por ultrassom pode ser complicado com a síndrome de Horner devido à distribuição imprevisível do anestésico local.
