BackgroundThe use of anesthetics and analgesic drugs and techniques in combination yields a multimodal effect with increased efficiency. In this case series, we aimed to evaluate the anesthetic effect of the thoracic paravertebral block (TPVB) and erector spinae plane block (ESPB) combination in patients, who underwent non-intubated video-assisted thoracoscopic surgery (NIVATS).MethodsMedical records of 16 patients, who underwent NIVATS for wedge resection under the combination of ESPB and TPVB were reviewed retrospectively. Demographic data of patients, duration of the sensory block, amount of the anesthetic agent used for premedication and sedo-analgesia, any presence of perioperative cough, operative times, postoperative visual analog scale (VAS) scores in the postoperative follow-up period, the need for additional analgesia, and patient satisfaction were reviewed.ResultsOf the patients included in the study, 12 were men and 4 were women. The mean age was 48.6 years and the mean BMI was 24.7 kg/m2. The mean time needed for the achievement of the sensorial block was 14 min and the mean skin-to-skin operative time was 21.4 min. During the procedure, patients received 81.5 ± 27.7 mg of propofol and 30 ± 13.6 micrograms of remifentanil infusions, respectively. The mean dose of ketamine administered in total was 58.1 ± 12.2 mg. Only 2 patients needed an extra dose of remifentanil because of recurrent cough. No patients developed postoperative nausea vomiting. During the first 24 h, the VAS static scores of the patients were 3 and below, while VAS dynamic scores were 4 and below. Morphine consumption in the first postoperative 24 h was 13.2 mg.ConclusionsIn conclusion, combined ESPB and TPVB with added intravenous sedo-analgesia in the presence of good cooperation between the surgical team and the anesthesiologist in the perioperative period can provide optimal surgical conditions including the prevention of cough in NIVATS. It is not sufficient to state that this combination is superior to alone ESPB or alone TPVB, as it is a preliminary study with a limited number of cases.© 2022. The Author(s).
