RESUMO
Purpose: In patients undergoing surgical resection for gastric cancer, perioperative hemodynamic fluctuations may affect organ perfusion, increase the incidence of postoperative complications, and prolong hospital stay. Patients and Methods: We retrospectively identified patients who underwent resection for gastric cancer at our institution from April 1, 2015 to October 30, 2018. Demographic information, perioperative data, and information on postoperative recovery were recorded. The primary outcome was length of postoperative hospital stay; the secondary outcome was incidence of postoperative complications. Propensity score matching was performed. The associations between perioperative factors and postoperative hospital stay were analyzed using multivariable logistic regression models in the full and matched cohorts. Results: In total, 933 patients were included; of these, 676 had diastolic hypotension (defined as diastolic blood pressure <60 mmHg for >10 min). In both cohorts, patients with diastolic hypotension had statistically significantly longer postoperative hospital stay (full: mean 14.5 ± standard deviation 10.2 vs 11.6 ± 6.5 days, P < 0.001; matched: 13.7 ± 9.9 vs 11.7 ± 6.6 days, P = 0.009) and a higher incidence of postoperative complications (full: 170 [25.1%] vs 27 [10.5%] cases, P < 0.001; matched: 60 [24.4%] vs 33 [13.4%] cases, P = 0.003), compared with patients without diastolic hypotension. After correction for confounding factors, intraoperative diastolic hypotension was associated with longer postoperative hospital stay in both the full and the matched cohort (full: HR, 1.535 [95% CI, 1.115-2.114], P = 0.009; matched: HR, 1.532 [95% CI, 1.032-2.273], P = 0.034). Conclusion: For patients with gastric cancer, intraoperative diastolic hypotension may increase the incidence of postoperative complications and prolong postoperative hospital stay.
RESUMO
BACKGROUND: In patients undergoing surgical resection for gastric cancer, postoperative complications-in particular, postoperative infections-remain an important problem and can result in delayed recovery and increased postoperative mortality. OBJECTIVE: To investigate the association between perioperative anesthesia management and postoperative infectious complications in patients undergoing resection for gastric cancer. DESIGN: Retrospective cohort study. SETTING: A single-center study performed from April 1, 2015, to June 30, 2018, at Peking University Cancer Hospital. PATIENTS: Patients who underwent resection for gastric cancer. MAIN OUTCOME MEASURES: Demographic information, perioperative data (including anesthesia-related data, surgery-related data, and cancer diagnosis), and information on postoperative recovery were recorded. The primary outcome was incidence of postoperative infection; the secondary outcome was length of hospital stay. The associations between perioperative factors and postoperative infectious complications were analyzed using multivariable logistic regression models and the classification tree method. RESULTS: A total of 880 patients were included in the study; of these, 111 (12.6%) had postoperative infectious complications during hospitalization, including 78 surgical site infections and 62 remote infections. After correction for confounding factors on logistic multivariable analysis, perioperative use of glucocorticoids was associated with a lower incidence of postoperative infection (hazard ratio 0.968, 95% confidence interval 0.939 to 0.997, P=0.029), and intraoperative systolic blood pressure <90 mmHg for >10 min was associated with a higher incidence of postoperative infection (hazard ratio 2.112, 95% confidence interval 1.174 to 3.801, P=0.013). In addition, older age, preoperative hypoproteinemia, and total gastrectomy were identified as independent predictors of postoperative infection. CONCLUSION: For patients with gastric cancer, perioperative use of glucocorticoids and avoiding intraoperative hypotension may decrease the incidence of postoperative infectious complications.
RESUMO
PURPOSE: To compare the efficacy of a lower dose background infusion of oxycodone for patient-controlled intravenous analgesia (PCIA) with the conventional dose, following intercostal nerve block, for the management of postoperative pain in patients undergoing thoracoscopic lobectomy for lung cancer. PATIENTS AND METHODS: This was a prospective, single-center, randomized, parallel-group, double-blind, controlled clinical trial. In total, 155 patients scheduled for elective radical lobectomy via video-assisted thoracoscopy were recruited from December 2018 to July 2019, of whom 140 were ultimately included in the study population. Patients were randomized to receive either oxycodone 0.25 mg/h (low-dose group, n=70) or oxycodone 0.5 mg/h (control group, n=70) as a background infusion for PCIA, following ropivacaine intercostal nerve block, for postoperative pain management. The primary endpoints were rest and dynamic visual analogue scale (VAS) scores within 72 h of the operation. The secondary endpoints were patient satisfaction scores, consumption of postoperative analgesics, times of patient-controlled analgesia (PCA), and adverse events. RESULTS: All 140 enrolled patients completed the study requirements and were included in the final analysis. The rest and dynamic VAS scores at 4 h, 24 h, 48 h, and 72 h postoperative were comparable between the low-dose group and the control group (P>0.05). However, the low-dose group had statistically significantly higher patient satisfaction scores (P<0.001) and lower postoperative analgesic consumption (P<0.001) as well as lower incidence of nausea and vomiting (P<0.05). The times of PCA was not statistically significantly different between the two groups, and no serious adverse events occurred in either group (P>0.05). CONCLUSION: A low-dose background infusion of oxycodone for postoperative PCIA can achieve a comparable analgesic effect to the conventional dose after thoracoscopic lobectomy for lung cancer. Furthermore, the low-dose regimen was associated with reduced consumption of oxycodone and increased patient satisfaction.

BACKGROUND: Multimodal opioid-sparing analgesia is a key component of an enhanced recovery pathway after surgery that aims to improve postoperative recovery. Transcutaneous electrical acupoint stimulation (TEAS) is assumed to alleviate pain and anxiety and to modify the autonomic nervous system. This study aimed to determine the efficacy of TEAS for sedation and postoperative analgesia in lung cancer patients undergoing thoracoscopic pulmonary resection. METHODS: A total of 80 patients were randomized into two groups: the TEAS group and the sham TEAS combined with general anesthesia group. Postoperative pain levels at six, 24, 48 hours, and one month after surgery were measured using the visual analogue scale (VAS). Bispectral index (BIS) score during the TEAS prior to anesthetic induction, Observer's Assessment of Alertness/Sedation (OAAS) score, sufentanil consumption during postoperative patient-controlled intravenous analgesia (PCIA), number of total and effective attempts of PCIA pump use, and incidence of postoperative nausea and vomiting were recorded and analyzed statistically. RESULTS: Patients in the TEAS group had significantly lower VAS scores at six, 24, and 48 hours after surgery (P < 0.01); lower BIS scores at 10, 20, and 30 minutes before induction (P < 0.01); lower levels of postoperative sufentanil consumption; lower number of PCIA attempts and effective rates (P < 0.01); lower incidences of nausea at 0, six, 24, and 48 hours; and lower incidence of vomiting at 24 hours after surgery (P < 0.05). The postoperative OAAS scores were similar between the groups. CONCLUSIONS: TEAS could be a feasible approach for sedation and postoperative analgesia in thoracoscopic pulmonary resection.

BACKGROUND: Patients with lung cancer are often accompanied by anxiety, which affects postoperative recovery. The aim of this study is to explore the effects of preoperative anxiety on early prognosis in patients after thoracoscopic lung cancer resection. METHODS: A total of 100 patients undergoing thoracoscopic resection of lung cancer were divided into 2 groups by hospital anxiety and depression scale (HADS): 44 in anxiety group (anxiety score>8) and 56 in control group (anxiety score<8). The primary endpoint: length of postoperative hospital stay. The secondary endpoint: length of hospital stay, visual analogue scale (VAS), the incidence of nausea and vomiting as well as postoperative new arrhythmia and the consumption of postoperative analgesic and rescue antiemetic. RESULTS: Compared with the control group, the length of postoperative hospital stay and hospital stay in the anxiety group were both significantly longer [(5.1±2.5) d vs (4.0±1.3) d, P<0.01; (10.9±4.0) d vs (9.1±4.1) d, P<0.05)], the VAS score and the incidence of nausea as well as arrhythmia were significantly increased [(4.7±1.9) vs (2.6±1.8), P<0.001; 40.9% vs 16.1%, P<0.01; 36.4% vs 20.7%, P<0.05], and the consumption of postoperative analgesic and rescue antiemetic were also significantly increased [(72.5±8.9) mL vs (68.2±9.4) mL, P<0.05; (2.1±2.9) mg vs (0.9±1.9) mg, P<0.05]. CONCLUSIONS: Preoperative anxiety can affect the early prognosis of patients after thoracoscopic lung cancer resection, prolong hospitalization time, increase the postoperative pain score and the incidence of postoperative nausea and new arrhythmia as well as the consumption of postoperative analgesic and rescue antiemetic.

In routine practice, one lung ventilation (OLV) is initiated upon pleural opening. We conducted a randomized controlled trial to compare lung collapse after preemptive OLV versus conventional OLV in thoracoscopic surgery. A total of 67 patients were enrolled (34 with conventional OLV; 33 with preemptive OLV). Preemptive OLV was conducted by closing the DLT lumen to the non-ventilated lung immediately upon assuming the lateral position with the distal port closed to the atmosphere until pleural opening (>6 minutes in all cases). Lung collapse was assessed at 1, 5, 10, 20, 30 and 40 minutes after pleural opening using a 10-point rating scale (10: complete collapse). The primary end point was the duration from pleural opening to satisfactory lung collapse (score of 8). Secondary end points included PaO2 and hypoxemia. The duration from pleural opening to satisfactory lung collapse was shorter in the preemptive OLV group (9.1 ± 1.2 vs. 14.1 ± 4.7 minutes, P < 0.01). PaO2 was comparable between the two groups prior to anesthetic induction (T0), and 20 (T2), 40 minutes (T3) after pleural incision, but was lower in the preemptive OLV group at zero minutes after pleural incision (T1) (457.5 ± 19.0 vs. 483.1 ± 18.1 mmHg, P < 0.01). No patients in either group developed hypoxemia. In summary, preemptive OLV expedites lung collapse during thoracoscopic surgery with minimal safety concern.

BACKGROUND: Perioperative management of pain associated with the prognosis of cancer patients. Optimization of perio-perative analgesia method, then reduce perioperative stress response, reduce opioiddosage, to reduce or even avoid systemic adverse reactions and elevated levels of tumor markers. Serum levels of tumor markers in patients with lung cancer are closely related to tumor growth. Clinical research reports on regional anesthesia effect on tumor markers for lung cancer are still very little in domesticliterature. The aim of this study is to evaluate the effects of thoracic paraverte-bral block on postoperative analgesia and serum level of tumor marker in lung cancer patients undergoing video-assisted thoracoscopic surgery. METHODS: Lung cancer patients undergoing video-assisted thoracoscopic surgery were randomly divided into 2 groups (n=20 in each group). The patients in group G were given only general anesthesia. The thoracic paravertebral blockade (PVB) was performed before general anesthesia in patients of group GP. The effect of PVB was judged by testing area of block. Patient controlled intravenous analgesia (PCIA) pump started before the end of surgery in 2 groups. Visual analogue scale (VAS) score was recorded after extubation 2 h (T1), 24 h (T2) and 48 h (T3) after surgery and the times of PCIA and the volume of analgesic drugs used were recorded during 48 h after surgery. The serum levels of carcino-embryonic antigen (CEA), carbohydrate antigen 199 (CA199), carbohydrate antigen 125 (CA125), neuron-specific enolase (NSE), cytokeratin 19 fragment (CYFRA21-1) and squamous cell carcinoma (SCC) in 40 lung cancer cases undergoing video-assisted thoracoscopic lobectomy were measured before operation and 24 h after operation. RESULTS: Forty American Society of Anesthesiologists (ASA) physical status I or II patients, aged 20 yr-70 yr, body mass index (BMI) 18 kg/m2-25 kg/m2, scheduled for elective video-assisted thoraeoscopic lobectomy, VAS scores at T1 and T2 were lower in group GP than those in group G (P=0.013, P=0.025, respectively), PCIA times during postoperative analgesia 24 h and 48 h were lower in group GP than those in group G (P=0.021, P=0.026, respectively), analgesic volume used during postoperative analgesia 24 h and 48 h were lower in group GP than those in group G (P=0.006, P=0.011, respectively). The level of tumor marker at post-operative were not significantly decreased than preoperative in both groups (P>0.05). CONCLUSIONS: Patients in group G feel more painful and a higher dosage of dezocine is required to relieve the pain than group GP. Thoracic paravertebralblock has no influence on serum level of tumor marker in lung cancer patients undergoing video-assisted thoraeoscopic lobectomy.
