RESUMO
BACKGROUND: Rectus sheath block (RSB) and transversus abdominis plane block (TAPB) have been shown to reduce opioid consumption and decrease postoperative pain scores in abdominal surgeries. However, there are no reports about the one-puncture technique of RSB combined with TAPB for perioperative pain management during laparoscopic upper abdominal surgery. METHODS: A total of 58 patients were randomly assigned to the control group (C), the TAP group (T), and the one-puncture technique of RSB combined with TAPB group (RT). The patients in group C did not receive any regional block. The patients in group T received ultrasound-guided subcostal TAPB with 30 mL of 0.33% ropivacaine on each side. The patients in the RT group received a combination of RSB and TAPB with 15 mL of 0.33% ropivacaine in each plane by one puncture technique. All patients received postoperative patient-controlled intravenous analgesia (PCIA) after surgeries. The range of blocks was recorded 20 min after the completion of the regional block. The postoperative opioid consumption, pain scores, and recovery data were recorded, including the incidence of emergence agitation (EA), the times of first exhaust and off-bed activity, the incidence of postoperative nausea and vomiting, dizziness. RESULTS: The range of the one-puncture technique in group RT covered all areas of surgical incisions. The visual analogue scale (VAS) score of the RT group is significantly lower at rest and during coughing compared to groups T and C at 4, 8, 12, and 24 h after surgery, respectively (P < 0.05). The consumption of sufentanil and the number of postoperative compressions of the analgesic pumps at 24 and 48 h in the RT group are significantly lower than those in groups T and C (P < 0.05). The incidence of EA in the RT group is significantly lower than that in groups T and C (P < 0.05). CONCLUSION: The one-puncture technique of RSB combined with TAPB provides effective postoperative analgesia for laparoscopic upper abdominal surgery, reduces the incidence of EA during PACU, and promotes early recovery.

INTRODUCTION AND IMPORTANCE: Positioning nodule with a steel wire in pulmonary surgery is a common preoperative step. To date, no reports have been published on the retention of steel wires in the body post-surgery, nor have there been studies describing the ultrasound-guided removal of foreign objects from the chest wall. This report describes a case of a foreign matter was removed from the chest wall by ultrasound-guided. CASE PRESENTATION: A 70-year-old woman underwent thoracoscope resection of a pulmonary nodule; however, a fragment of the positioning steel wire remained in the chest wall during the surgery. The anesthetist located the residual steel wire using ultrasound, and subsequently, the surgeon successfully removed it. CLINICAL DISCUSSION: Detection of foreign matter in the body is rare and usually associated with trauma or accidental retention of materials such as absorbable gelatin sponges or sutures during surgery, which are often found using X-rays. This process is often time-consuming, and X-rays being radioactive are potentially harmful to patients and medical workers. Ultrasonic waves are safe and offer a convenient alternative for such procedures. We removed the residual steel wire through a 0.5 cm skin incision, this method neither caused trauma nor increased costs. CONCLUSION: Ultrasonography-assisted positioning is a rapid, convenient, and safe technique, promising to enhance future surgical interventions.
RESUMO
BACKGROUND: Advancing the endotracheal tube (ETT) over a flexible bronchoscope (FB) during awake fiber-optic intubation (AFOI) is often impeded. Various maneuvers and tracheal tubes designed to overcome this obstruction may also be unsuccessful or costly. OBJECTIVE: The current study aimed to assess how the novel double configuration ETT affected AFOI success rates on the first attempt. METHODS: A randomized controlled experiment including 40 individuals receiving awake fiber-optic orotracheal intubation was performed in a 1:1 ratio with a single ETT railroaded with its bevel posteriorly (ST) or railroading with a double setup ETT (DT) over a flexible videoscope (FVS) for tracheal intubation. The number of intubation attempts, time spent intubating, and adverse events were examined and compared between the two groups. RESULTS: Twenty patients received a single ETT railroaded with the bevel posteriorly, and 20 patients received railroading with the double setup ETT during AFOI. Intubation on the first attempt was significantly greater in the DT group (90%) than in the ST group (35%). The intubation time was considerably shorter for the DT group (12.8 [7.8-16.9] s) when compared with the ST group (27.9 [16.3-91.0] s). Five patients were intubated by the alternative technique after failure to intubate for several attempts, and 3 cases were found to have a crease in the FVS after intubation in group ST. During topical anesthetic, three individuals in each group experienced transient oxygen desaturation. CONCLUSIONS: Our study discovered that the novel double setup tube could significantly improve the intubation success rate on the first attempt during AFOI for patients with challenging airway when a strategy based on a reduced gap between ETT and FB could not be applied.

With the acceleration of an aging population, postoperative cognitive dysfunction (POCD) has become a large problem. Preoperative carbohydrate (CHO) loading has been reported to attenuate surgery stress response and insulin resistance. The present study aimed to investigate whether preoperative vitamin-rich CHO loading has an effect on POCD, endoplasmic reticulum (ER) stress, and apoptosis. Eighty male Sprague-Dawley rats (20-month old) were randomly assigned to four groups (20 per group): control group (no anesthesia and surgery), fasting group (fasting 14â¯h before surgery), water group (oral water 3â¯h before surgery), and CHO group (oral vitamin-rich CHO 3â¯h before surgery). The POCD rat model was established by splenectomy under intraperitoneal injection of pentobarbital sodium. Cognitive function was assessed using the Morris water maze (MWM) after surgery. The levels of endoplasmic reticulum (ER) stress markers and apoptosis related proteins in the hippocampus were examined by western blot analysis. The vitamin-rich CHO treated animals performed better in the MWM tests than the animals in the fasting and water groups. Furthermore, preoperative CHO loading reduced ER stress and neuronal apoptosis in the hippocampus of aged rats, as indicated by the protein biomarkers of GRP78, eIF2a, Beclin1, Bax, and Bcl-2. In conclusion, preoperative vitamin-rich CHO loading could improve POCD by attenuating ER stress and neural apoptosis, providing a basis as a potential treatment against POCD.

BACKGROUND: Preoperative oral carbohydrates has been suggested to attenuate insulin resistance and decrease postoperative complications. In this study, a vitamin-rich carbohydrate beverage was administered before surgery in an animal model to investigate its effects on the surgical stress response and S-100ß levels. METHODS: Thirty aged male Sprague-Dawley rats were randomly assigned to three groups: control group (n = 6), fasting group (n = 12), and carbohydrate-treated group (CHO group, n = 12). Rats in the control group were not given any treatment. Rats in the fasting group received splenectomy after 12 h of fasting. In the CHO group, rats were given 5 ml of vitamin-rich carbohydrate by gavage 2 h before surgery. Fasting plasma glucose, insulin, insulin resistance (HOMA-IR index, IRI), the S-100ß protein level, and the inflammatory mediators IL-1ß, IL-6 and TNF-α were assessed after surgery (postoperative day (POD) 1 and 3). RESULTS: Postoperative insulin resistance was significantly greater in the fasting group than in the control and CHO group. The median plasma S-100ß level was significantly higher in the fasting group than in the control and CHO groups on POD 1. The median plasma IL-1ß level was significantly lower in the CHO group than in the fasting group on POD 1; however, no other differences in the concentrations of immunological biomarkers of stress were found between the fasting group and the CHO group. CONCLUSIONS: Vitamin-rich carbohydrate pretreatment attenuated the metabolic aspect of the surgical stress response and decreased the level of plasma S-100ß, which may decrease the risk of postoperative complications in elderly rats.
