RESUMO

BACKGROUND: Transversus abdominis plane block (TAPB) is commonly used for postoperative pain control after laparoscopic cholecystectomy. However, few studies have analyzed its effect on pulmonary function. The goal of this study was to elucidate the effect of ultrasound-guided bilateral TAPB on pulmonary function preservation and analgesia after laparoscopic cholecystectomy. METHODS: We enrolled 58 patients who underwent laparoscopic cholecystectomy. Among them, 53 were randomized to group T (n = 27) and group C (n = 26). Group T and group C received ultrasound-guided bilateral TAPB with 40 ml of 0.375% ropivacaine and 40 ml of 0.9% normal saline, respectively. Visual analog scale (VAS) scores, patient-controlled analgesia (PCA) consumption, forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), FEV1/FVC, peak expiratory flow rate (PEF), and modified Borg scale scores were measured until 24 h post-surgery. RESULTS: The VAS scores were significantly lower in group T than in group C at 1 and 8 h after the surgery. PCA consumption was significantly lower in group T than in group C at all postoperative time points. FEV1, PEF, and FEV1/FVC were more preserved in group T than in group C at 1 h. Group T had significantly lower modified Borg scale scores than did group C at 1 and 8 h. CONCLUSION: Ultrasound-guided TAPB is effective in pulmonary function preservation and pain control after laparoscopic cholecystectomy. Therefore, it could be a great option for multimodal analgesia, preservation of pulmonary function, prevention of pulmonary complications including atelectasis, and promotion of postoperative recovery after laparoscopic cholecystectomy. CLINICAL REGISTRATION: This study was enrolled in the Clinical Research Information Service (Clinical Research Information Service, KCT0004435, Hwa Yong Shin, 2019-08-19).

RESUMO

BACKGROUND: The adductor canal block (ACB) is an effective intervention for postoperative analgesia following total knee arthroplasty (TKA). However, the ideal ACB regimen has not yet been established. We compared the analgesic effects between a continuous ACB group and fentanyl-based intravenous patient-controlled analgesia (IV-PCA) with a single-shot ACB group. METHODS: Patients who underwent TKA were randomly allocated to either a continuous ACB group (Group CACB) or IV-PCA with a single-shot ACB group (Group IVACB). Before the surgery, ultrasound guided ACB with 0.5% ropivacaine 20 cc was provided to all patients. Before skin incision, the infusion system (0.2% ropivacaine through an adductor canal catheter in group CACB vs. intravenous fentanyl in group IVACB) was connected. The postoperative pain severity; the side effects of local anesthetics and opioids; administration of rescue analgesics and anti-emetics; and sensorimotor deficits were measured. RESULTS: Postoperative pain severity was significantly higher in the IVACB group at 30 min, 4 h, 24 h, and 48 h after surgery. The averages and standard deviations (SD) of the NRS score of postoperative pain were 0.14 ± 0.37, 4.57 ± 2.37, 6.00 ± 1.63, and 4.28 ± 1.49, respectively in the IVACB group. Rescue analgesic requirements and quadriceps muscle strength were not statistically different between the groups throughout the postoperative period. Moreover, rescue antiemetic requirements were higher in group IVACB than group CACB. CONCLUSIONS: In this study, the continuous ACB provided superior analgesia and fewer side effects without any significant motor deficit than the IV-PCA with a single-shot ACB.

RESUMO

PURPOSE: The present visual and electromyographic study was designed to evaluate muscle fasciculations caused by succinylcholine in adults pretreated with either remifentanil 1.5 microg/kg or saline. MATERIALS AND METHODS: The effect of remifentanil on succinylcholine-induced muscle fasciculations was studied using a double-blind method in 40 adults. After i.v. pretreatment with either remifentanil 1.5 microg/kg (remifentanil group, n = 20) or an equivalent volume of i.v. saline (saline group, n = 20), patients were anaesthetized with a 2.0 mg/kg of i.v. propofol followed by i.v. succinylcholine 1.0 mg/kg. Intensity and duration of muscle fasciculation following i.v. succinylcholine administration were recorded. Electromyography (EMG) was used to quantify the extent of muscle fasciculation following i.v. succinylcholine injection. Myalgia was evaluated 24 hours after induction time. Serum potassium levels were measured five minutes after i.v. succinylcholine administration and creatine kinase (CK) levels 24 hours after induction time. RESULTS: Compared to saline treated controls, remifentanil decreased the intensity of muscle fasciculations caused by i.v. succinylcholine [fasciculation severity scores (grade 0 to 3) were 2/1/12/5 and 3/13/4/0 (patients numbers) in the saline group and the remifentanil group, respectively, p < 0.001]. The mean (SD) maximum amplitude of muscle action potential (MAP) by EMG was smaller in the remifentanil group [283.0 (74.4) microV] than in the saline group [1480.4 (161.3) microV] (p = 0.003). Postoperative serum CK levels were lower in the remifentanil group (p < 0.001). Postoperative myalgia was not different between the two groups. CONCLUSION: Remifentanil 1.5 microg/kg attenuated intensity of muscle fasciculations by succinylcholine.

RESUMO

The airway management for patients with critical airway problems continues to be a challenge to the anesthesiologist. In general cases, conventional ventilation techniques have been used successfully. These include fiberoptic bronchoscope guided intubation, supraglottic airway, endotracheal or endobronchial intubation at operative field, high frequency jet ventilation, etc. However, patients with near-fatal airway obstruction or severely depressed pulmonary function that is refractory to conventional ventilation methods also present. In these cases, cardiopulmonary bypass or extracorporeal membrane oxygenation (ECMO) can be used. Although these situations are uncommon indications for ECMO, ECMO can be a potential option for these life threatening conditions. Especially, venovenous (VV) ECMO can be used for pure pulmonary support. We describe three cases of airway surgery requiring ECMO. VV ECMO was established in all cases. ECMO provided adequate temporary pulmonary support and all patients weaned from ECMO successfully without any complication.
