RESUMO
INTRODUCTION: Postoperative delirium is common, with a reported incidence of 11% to 80% in critically ill patients. Delirium is an independent prognostic factor for poor hospital outcomes. Low vitamin D concentrations are associated with a decline in cognitive function. We therefore tested the hypothesis that low preoperative serum 25-hydroxyvitamin D [25(OH)D] concentrations are associated with postoperative delirium in critically ill patients. METHOD: We conducted a retrospective analysis of adults in a surgical intensive care unit for at least 48 hours immediately after non-cardiac and non-neurosurgical operations at Cleveland Clinic between 2013 and 2018. Delirium was assessed by trained nurses using CAM-ICU twice daily for the initial 5 postoperative days. Any positive value was considered evidence of delirium. We assessed the association between 25(OH)D concentrations within a year before surgery and the incidence of postoperative delirium using logistic regression, adjusted for potential confounders. A linear spline term with a knot at 30 ng/ml, the threshold for normal 25(OH)D concentration, was added to accommodate a nonlinear relationship between 25(OH)D concentrations and delirium. RESULTS: We included 632 patients, who had a mean (SD) 25(OH)D concentration of 25 (15) ng/ml; 55% (346/632) experienced delirium. We observed an adjusted odds ratio of 1.4 (95% CI: [1.1, 1.8], P = 0.01) for delirium per 10 ng/ml decrease in 25(OH)D concentrations when patients' 25(OH)D concentrations were less than 30 ng/ml. In patients whose 25(OH)D concentrations were at least 30 ng/ml, the adjusted odds ratio was 0.9 (95% CI: [0.7, 1.1], P = 0.36). CONCLUSION: Preoperative 25(OH)D concentrations are associated with postoperative delirium in patients whose concentrations are below the normal threshold, but not at concentrations ≥30 ng/ml. A trial will be needed to determine whether the relationship is causal, and whether vitamin D supplementation before surgery might reduce the incidence of delirium.

OBJECTIVE: Although prevention of radial artery thrombosis and cardiac complications after interventions using radial access is well investigated, there is yet no clinical study that completely evaluated access-related complications. However, there is still no consensus on what exact treatment should be used in these patients. In clinical practice, analgesic, anticoagulant, and antiplatelet treatments usually improve symptoms in patients with pain; however, in some patients, complaints may persist and may not respond to these treatments. In these patients, low-risk embolectomy with a small skin incision may be beneficial. METHODS: A total of 102 patients with radial artery thrombosis after cardiac catheterization were included in the study between 2016 March and 2018 December. After the patients' initial evaluation, anticoagulation with enoxaparin or tinzaparin and antiplatelet therapy with acetylsalicylic acid and oral/local analgesic/anti-inflammatory and local anesthetic therapy were administered for 1 month. Patients whose symptoms resolved after medical treatment were followed up as outpatients. Embolectomy was performed in consenting patients who did not respond to the medical treatment. RESULTS: Of 102 patients included in the study, 33 underwent embolectomy, whereas 69 received only medical treatment. None of the patients experienced any complications, morbidity, or mortality in the peroperative period and during the medical treatment. The pretreatment symptom scores of patients who actively use their hands in daily life and profession were significantly higher than the scores of patients who are relatively less active (P = .013). Pretreatment symptom scores were negatively correlated with age (r = -0.584); symptom scores increased significantly with the decrease of patient age. No benefit from medical treatment and need for surgery was significantly greater in patients who are younger and use their hands actively in daily life and profession (P = .028). The decrease in symptom scores after treatment was significantly greater in the surgical group than in the medical group (P = .003). CONCLUSION: Radial access should be exercised with care in patients who may develop significant thrombosis-related complaints and it is necessary to decide whether radial access is essential. If patients have ongoing symptoms despite medical treatment, embolectomy can be considered as a treatment option.

OBJECTIVES: To determine if the infraclavicular brachial plexus block can be applied with lower volume of local anesthetic. DESIGN: Randomised, double-blinded clinical trial. PATIENTS: 60 patients aged 5-15years with ASA I-II who underwent emergent or elective arm, forearm or hand operations were included in the study. INTERVENTIONS: Patients were divided into two groups randomly; standard volume local anesthetic administered group (Group S, n=30) and low volume anesthetic administered group (Group L, n=30). MEASUREMENT: Postoperative pain scores, sensory and motor block durations were noted. MAIN RESULTS: Pain scores (Wong-Baker Face Scale) were evaluated and the results were detected to be similar at all times (30min, 1, 2, 4, 8, 12, 24h). Durations of motor block were 168(±16) minutes and 268(±15) minutes in Group L and Group S respectively and the difference was statistically significant (p<0.001). Durations of sensory block were 385(±26) and 402(±39) in Group L and Group S respectively and no statistically significant difference was detected (p=0.064). CONCLUSION: Similar block success, postoperative sensory block durations and pain scores could be obtained during infraclavicular brachial plexus in pediatric patients with lower local anesthetic volumes.

PURPOSE: The effect of a single-dose of pre-emptive pregabalin is still unknown, although it is used as an adjuvant in controlling acute postoperative pain. The purpose of this study was to evaluate the effects of pre-emptive single-dose pregabalin on postoperative acute pain and 24-hour opioid consumption in patients who underwent double-jaw surgery. PATIENTS AND METHODS: Forty patients (18 to 45 yr old; American Society of Anesthesiologists status I to II) for whom elective double-jaw surgery was planned under general anesthesia were included in this study, which had been planned as a prospective, randomized, and double-blinded study. Patients were randomly divided into 2 groups: the pregabalin group (n = 20) was given pregabalin 150 mg orally 1 hour before general anesthesia and the placebo group (n = 20) was given an oral placebo capsule. The groups were administered the routine general anesthesia protocol. Postoperative analgesia was performed intravenously in the 2 groups twice a day with dexketoprofen trometamol 50 mg and patient-controlled analgesia with fentanyl. Postoperative analgesia was evaluated using the visual analog scale (VAS). Fentanyl consumption, additional analgesia requirement, and side-effects were recorded during the first 24 hours after surgery. Descriptive and bivariate statistics were computed, and significance was set at a P value less than .05. RESULTS: Compared with placebo, the VAS score was statistically lower in the pregabalin group during the early postoperative period (P < .05). The 24-hour opioid consumption was significantly higher in the placebo group compared with the pregabalin group (509.40 ± 261.56 vs. 260.10 ± 246.53 µq, respectively; P = .004). In addition, the analgesia requirement was statistically lower in the pregabalin group (P < .05). Nausea or vomiting was observed more often in the placebo group, whereas other side-effects were similar for the 2 groups. CONCLUSION: A single 150-mg dose of pre-emptive pregabalin decreased postoperative opioid consumption in the first 24 hours after double-jaw surgery. Multimodal analgesia techniques that contain pre-emptive analgesia can be used successfully in preventing postoperative pain caused by orthognathic surgery.

BACKGROUND: This study investigated the effects of metamizole and paracetamol on pain and oxidative stress induced by scalpel incision and carrageenan in rats. MATERIALS AND METHODS: Total of 144 rats were divided into groups of 12 animals. Six groups each were used for scalpel incision and carrageenan tests. Pain was inflicted by applying a scalpel incision or carrageenan. Pain-created groups by scalpel incision received metamizole (SIM) or paracetamol (SIP) at doses of 250 or 500 mg/kg. Pain-created groups by carrageenan received metamizole (CAM) or paracetamol (CAP) at doses of 250 or 500 mg/kg. Analgesic activity was determined by Basile Algesimeter. The COX-2 and MPO gene expressions were determined, and malondialdehyde and tGSH were measured in rat paws. RESULTS: In the scalpel incision test, pain was reduced in groups of SIM-250 and SIM-500 in the first hour by 65.2% and 91.3%, respectively, and in the third hour by 51.9% and 77.8%, respectively, compared with the SIC group. In SIP-250 and SIP-500 groups, pain was reduced in the first hour by 43% and 74%, respectively, and by 33.4% and 59.3%, respectively, in the third hour compared with the SIC group. In the carrageenan test, in groups CAM-250 and CAM-500, pain was reduced in the first hour by 72.3% and 86.1%, respectively, and by 65.8% and 71.4%, respectively, in the third hour compared with the CCG group. In groups CAP-250 and CAP-500, pain was reduced in the first hour by 52.8% and 69.4%, respectively, and by 28.6% and 25.8%, respectively, in the third hour compared with the CCG group. Metamizole inhibited COX-2 gene expression at a dose of 500 mg/kg in the carrageenan test. At doses of 250 and 500 mg/kg, metamizole reduced COX-2 and MPO gene expressions and oxidative stress induced by scalpel incision or carrageenan. But both doses of paracetamol were unable to suppress that parameters. CONCLUSIONS: Our results show that metamizole is more effective than paracetamol for treating surgical trauma-related pain, inflammation, and oxidative stress and hence may be a preferential drug to paracetamol.
