RESUMEN
Thromboses that form in the pedicle after free flap and/or replantation may result in the loss of the flap and/or limb. Ticagrelor is an adenosine diphosphate (ADP) receptor antagonist antithrombotic that can inhibit ADP-dependent platelet activation and aggregation. It is clinically used in acute coronary syndrome and unstable angina. However, its effect on microarterial anastomoses has not been investigated in the literature. An experimental thrombosis model was developed in both femoral arteries of a total of 40 rats. Twenty rats were randomly selected as the drug-free control group, and 20 rats were randomly selected as the ticagrelor group. The rats in the ticagrelor group were administered a 20 mg/kg loading dose orally by gavage 24 h before the experiment, and a maintenance dose of 2x10 mg/kg ticagrelor for 14 days after surgery. After the experiment, the femoral artery was evaluated for macroscopic and microscopic thrombosis, inflammation, edema, and endothelialization. Macroscopically and microscopically, thrombosis was observed at rates of 73.3% and 33.3% in the control group and the ticagrelor group, respectively. Inflammation in the vessel wall was found as 56.7% in the control group and 16.7% in the ticagrelor group. Edema in the vessel wall was found in 63.3% of the control group and 20% of the ticagrelor group. A statistical difference was found between the two groups in terms of thrombosis, inflammation, and edema. Both groups had similar characteristics in terms of endothelialization. Ticagrelor has a reducing effect on thrombosis in the microarterial tuck model.

PURPOSE: Obese patients have a significantly higher risk of adverse effects associated with general anesthesia. The purpose of this study was to evaluate the effects of Patient State Index (PSI) monitoring on recovery from anesthesia and the incidence of any postoperative complications among patients undergoing bariatric surgery with total intravenous anesthesia (TIVA) and inhalational anesthesia. DESIGN: This prospective, double-blind, and randomized controlled trial was conducted between February 2017 and August 2017 and included 120 morbidly obese patients (body mass index >40 kg/m2). METHODS: Patients were randomly divided into four groups; group P-PSI (n = 30): TIVA with PSI monitoring; group P (n = 30): TIVA without PSI monitoring; group D-PSI (n = 30): desflurane with PSI monitoring; and group D (n = 30): desflurane without PSI monitoring. The discharge time from the postanesthesia care unit (PACU), postoperative complications, and hemodynamic parameters were recorded and evaluated. FINDINGS: No significant differences were found in demographic data, duration of anesthesia, admittance to PACU, discharge from PACU, modified Aldrete scores, and perioperative mean blood pressure and heart rate. Nausea and vomiting scores were significantly lower in group P-PSI, group P, and group D-PSI compared with group D. CONCLUSIONS: Although TIVA and inhalational anesthesia can be safely used for obese patients, intraoperative PSI monitoring may decrease the discharge time from PACU and reduces incidence of postoperative nausea and vomiting caused by inhalation anesthetics.

BACKGROUND: The interest in and demand for post-bariatric surgery have increased along with the increase in obesity surgery. Belt lipectomy, during which a circular correction is made in the center of the trunk, is the most commonly performed among these surgical techniques. Postoperative pain is an important problem due to the size of the surgical site and stretched closure. In this study, it was aimed to evaluate the intraoperative and postoperative narcotic analgesic consumption, postoperative analgesic requirement, postoperative visual analog scale (VAS) scores, postoperative nausea and vomiting (PONV), and the first mobilization time in patients with and without erector spinae plane block (ESPB). METHODS: The files of patients who had undergone belt lipectomy between 2016 and 2019 in our hospital were retrospectively reviewed. Patients who received ESPB were called group 1, and those who did not undergo ESPB were called group 2. Their demographic characteristics, intraoperative and postoperative narcotic and non-narcotic analgesic consumption, VAS scores, PONV, and the first mobilization times were recorded. RESULTS: The files of a total of 51 patients, including 23 patients in group 1 and 28 patients in group 2, were reviewed. It was determined that intraoperative and postoperative narcotic analgesic consumption (p < 0.005), PONV (p < 0.005), and the first mobilization time (p < 0.005) were significantly lower in group 1 compared with group 2. CONCLUSION: The use of the ESP block in belt lipectomy surgeries significantly reduces intraoperative and postoperative narcotic analgesic consumption and pain scores.

PURPOSE: Unexpected cancellations of planned elective procedures are a global problem for hospitals, causing a waste of hospital resources and manpower, and reduces the efficiency of hospitals. In this study, we tried to identify the causes of cancellations of elective procedures, and to examine the relationship between the causes. DESIGN: A retrospective, descriptive single-center study. METHODS: Nine thousand five hundred sixty-six elective procedures scheduled between January 2015 and December 2015 were retrospectively examined. Reasons for cancellation, the associated surgical clinic, and the day and season of the canceled procedures were recorded. FINDINGS: Of the total 9,566 procedures, 496 (5.2%) were canceled. Of the cancellations, 31.3% were due to patient-related reasons, 29.2% because of inadequate anesthesia preparation, and 19% because of nonavailability of operating rooms. CONCLUSIONS: Cancellation of elective surgeries causes a waste of time and resources. Determining the reasons for cancellations to reduce cancellation rates is important for each hospital.

OBJECTIVES: In this study, characteristics and analgesic treatment of patients with pancreatic cancer who applied to the algology clinic were evaluated. METHODS: Demographic characteristics, pathologic diagnosis, metastasis, cancer treatment, and analgesic interventions in 60 patients with pancreatic cancer, referred to the algology clinic, were examined. RESULTS: The application time of the patients to the clinic was 3.9+-0.92 months after the diagnosis, and the visual analog scale (VAS) was 6.96+-0.11 at the initial assessment. According to the analgesic step ladder protocol, a nonopiod + weak opioid + strong opioid (transdermal) were applied in 58.33%, a nonopioid + weak opioid + strong opiod (oral) in 5%, and nonopiod + weak opioid in 36.66% of the patients. Adjuvant pain medications were used in 68.33% of the patients (benzodiazepine, 80.48%; antidepressant, 19.51%), while no adjuvant was used in 31.66% of the patients. While the mean survival time for patients with pancreatic cancer changed from 3 to 6 months, it was 8.48+-7.46 months for patients who applied to the pain clinic. CONCLUSION: Abdominal pain in pancreatic cancer is the most common symptom that negatively affects the quality of life. A good analgesia improves the survival, while pain decreases the survival. The results of the present study demonstrated that the survival of the patients with metastatic pancreatic cancer who received effective pain therapy in the algology clinic may be longer.

BACKGROUND: Postoperative nausea and vomiting (PONV) is one of the most common complications during the postoperative period. In the literature, there are many factors associated with PONV risk, but it is claimed that inflammation increases this risk. The neutrophil-to-lymphocyte ratio (NLR) is a cheap parameter to use in the diagnosis and follow-up of systemic inflammatory diseases. In this study, we aimed to investigate whether the preoperative NLR was a marker for PONV and to determine its relation with antiemetic use. METHODS: Eighty patients who were planned to undergo elective septorhinoplasty and were in ASA I-II were prospectively included in the study. The NLR value was calculated by dividing the number of neutrophils by the number of lymphocytes obtained from the preoperative complete blood count. The patients were divided into two groups of 40 patients: patients with an NLR < 2 (group 1) and patients with an NLR > 2 (group 2). Nausea and vomiting during the first 24 h in the recovery room and in the related clinic and antiemetic requirement were recorded. RESULTS: The rate of nausea-vomiting in the recovery room and in the postoperative 24-h period in group 1 was significantly lower than in group 2 (p < 0.05). The rate of use of antiemetics in the recovery room and in the postoperative 24-h period in group 1 was significantly lower than in group 2 (p < 0.05). CONCLUSION: NLR values above 2 calculated in the preoperative period may be an indicator of PONV risk. Antiemetic prophylaxis may be given according to this value.

The rationale behind intradiscal O2-O3 therapy is the pain elicited by the mechanical compression of the nerve root, which is associated with periganglionic and periradicular inflammation. This study aimed to determine the effect of intradiscal ozone injection on pain score and satisfaction of patients with low back pain (LBP) secondary to disc herniation. Patients with LBP diagnosed with disc herniation were enrolled in this clinical trial. After prepping and draping the area, intradiscal injection of ozone/oxygen mixture (10 ml, 25µg/ml) was performed under fluoroscopy guide (c-arm). Pain score and patient satisfaction were assessed prior to the injection (baseline) and 1, 3, 6, 12 and 24 months after the injection. Sixty three patients (24 males, 39 females) with mean age of 53.3 ±2.0 y enrolled in the study. The mean±standard deviation (SD) of pain score before intervention was 6.968 ±0.11. Pain score was reduced to 4.25±0.19 at 1 month, 4.33±0.20 at 3 months, 4.87 ±0.21 at 6 months and 5.22 ±0.20 at 24 months. According to the modified MacNab scale success of pain relief was as follows: excellent: 4 (6.3%), good: 17 (26.98 %), sufficient: 13 (20.63 %), poor: 13 (20.63 %), no result: 11 (17.46%), negative: 4 (6.3 %). Intradiscal ozone therapy was determined to provide improved outcomes in patients with single level of bulging and protrusion.

PURPOSE: We evaluated the effects of body mass index (BMI) on thermoregulation in obese patients scheduled to undergo laparoscopic abdominal surgery. METHODS: Sixty patients scheduled to undergo laparoscopic abdominal surgery with no pre-medication were included in the study. The patients were classified into 4 groups according to BMI <24.9, 25-39.9, 40-49.9, and >50. Anesthesia was provided with routine techniques. Tympanic and peripheral temperatures were recorded every 5 minutes starting with the induction of anesthesia. The mean skin temperature (MST), mean body temperature (MBT), vasoconstriction time, and vasoconstriction threshold that triggers core warming were calculated with the following formulas: MST = 0.3 (Tchest + Tarm) + 0.2 (Tthigh + Tcalf). MBT was calculated using the equation 0.64Tcore+0.36Tskin, and vasoconstriction was determined by calculating Tforearm-Tfinger. RESULTS: There was no significant difference between the groups in terms of age, gender, duration of operation, and room temperature. Compared to those with BMI <24.9, the tympanic temperature was significantly higher in those with BMI =25-39.9 in the 10th, 15th, 20th, and 50th minutes. In addition, BMI =40-49.9 in the 5th, 10th, 15th, 20th, 25th, 30th, 40th, 45th, 50th, and 55th minutes and BMI >50 in the 5th, 10th, 15th, 20th, 25th, 30th, 50th, and 55th minutes were less than those with BMI <24.9 (P<0.05). There was no significant difference in terms of MST and MBT. Vasoconstriction occurred later, and that vasoconstriction threshold was significantly higher in patients with higher BMIs. CONCLUSION: Under anesthesia, the core temperature was protected more easily in obese patients as compared to nonobese patients. Therefore, obesity decreases the negative effects of anesthesia on thermoregulation.
