RESUMEN
BACKGROUND: Septorhinoplasty (SRP) is one of the most commonly performed procedures in the world for functional and aesthetic purposes. The present study was aimed to compare the effects of hypocapnia and hypercapnia regarding the total amount of intraoperative bleeding, surgical field quality, and surgeon satisfaction level. METHODS: In this randomized prospective clinical study, eighty patients with American Society of Anesthesiologists I-II and were 18-45 years old scheduled for septorhinoplasty were randomly allocated to group hypocapnia [end-tidal carbon dioxide (EtCO2) 30 ± 2 mmHg] and group hypercapnia (EtCO2 40 ± 2 mmHg). We evaluated the total amount of intraoperative bleeding, the surgical field quality, surgeon satisfaction level, hemodynamics and peri- and postoperative adverse events. RESULTS: Group hypocapnia significantly reduced the total amount of intraoperative bleeding (p < 0.001). The surgical field quality and surgeon satisfaction level in group hypocapnia were significantly better than group hypercapnia (p < 0.001). EtCO2 levels of group hypocapnia were significantly lower than group hypercapnia at all time points (p < 0.001 for all time points). There were no significant differences between the groups in terms of heart rate and mean arterial pressure at all time points. There were no significant differences between the groups in terms of adverse events CONCLUSIONS: The results of this double-blind randomized clinical trial showed that reducing the amount of intraoperative bleeding for patients with hypocapnia undergoing SRP through known methods (e.g., reverse Trendelenburg head-up position, positive end-expiratory pressure limiting, controlled hypotension, and use of topical vasoconstrictors, corticosteroids, and tranexamic acid) would improve the quality of the surgical field and raise the surgeon satisfaction level.

BACKGROUND: There are doubts among anesthesiologists on the use of the Laryngeal Mask Airway (LMA) in nasal surgeries because of concerns about the occurrence of blood leakages to the airway. We hypothesized that the use of LMA-Supreme (LMA-S) in nasal surgery is comparable with endotracheal tube (ETT) according to airway protection against blood leakage through the fiberoptic bronchoscopy, oropharyngeal leakage pressure (OLP), heart rate (HR), mean arterial pressure (MAP), and postoperative adverse events. METHODS: The present study was conducted in a prospective, randomized, single-blind, controlled manner on 80 patients, who underwent septoplasty procedures under general anesthesia, after dividing them randomly into two groups according to the device used (LMA-S or ETT). The presence of blood in the airway (glottis/trachea, distal trachea) was analyzed with the fiberoptic bronchoscope and a four-point scale. Both groups were evaluated for OLP; HR; MAP; postoperative sore throat, nausea, and vomiting; dysphagia; and dysphonia. RESULTS: In the fiberoptic evaluation of the airway postoperatively, less blood leakage was detected in both anatomic areas in the LMA-S group than in the ETT group (glottis/trachea, p = 0.004; distal trachea, p = 0.034). Sore throat was detected less frequently in the LMA-S group at a significant level in the 2nd, 6th, and 12th hours of postoperative period; however, other adverse events were similar in both groups. Hemodynamic parameters were not different between the two groups. CONCLUSION: The present findings demonstrate that the LMA-S provided more effective airway protection than the ETT in preventing blood leakage in the septoplasty procedures. We believe that the LMA-S can be used safely and as an alternative to the ETT in septoplasty cases. TRIAL REGISTRATION: This trial is registered at the US National Institutes of Health ( ClinicalTrials.gov ) # NCT03903679 on April 5, 2019.

OBJECTIVES: To investigate the relationships between secondhand smoke (SHS) exposure and oxygenation during one-lung ventilation (OLV) in lobectomy surgery and between SHS exposure and postoperative analgesic consumption. DESIGN: Prospective study. SETTING: University, Faculty of Medicine, operating room. PARTICIPANTS: Sixty adult patients with American Society of Anesthesiologists score II to III, aged 18 to 65 years, with a body mass index (BMI) <35 kg/m2 scheduled for lobectomy surgery by open thoracotomy. INTERVENTIONS: Patients were divided into 2 groups: the SHS group (nâ¯=â¯30) (urine cotinine level ≥6.0 ng/mL) and the NS (nonsmoker) group (nâ¯=â¯30) (urine cotinine level <6.0 ng/mL and no smoking history). SHS exposure was defined according to a previously published algorithm. MEASUREMENTS AND MAIN RESULTS: Noninvasive blood pressure, electrocardiography, capnography, and peripheral oxygen saturation were monitored, and intra- and postoperative arterial oxygen tension (PaO2), arterial carbon dioxide tension (PaCO2), and intraoperative peak airway pressure were compared between the 2 groups. Postoperative analgesic consumption was calculated. No significant differences in demographics or preoperative data were noted between the 2 groups. PaO2 values 10 minutes after OLV onset and 10 minutes after the end of OLV were increased significantly in the NS group compared with those in the SHS group (p < 0.05). PaO2 values after 10 minutes of OLV in the NS and SHS groups were 285.5 ± 90 mmHg and 186.7 ± 66 mmHg, respectively. PaO2 values after OLV termination in the NS and SHS groups were 365.8 ± 58 mmHg and 283.6 ± 64 mmHg (p < 0.05), respectively. PaCO2 values 10 minutes after OLV onset, 10 minutes after the end of OLV, at the end of surgery, and upon arrival in the intermediate care unit were significantly different between the 2 groups (p < 0.05). CONCLUSION: The present study demonstrated that during OLV, patients exposed to SHS exhibited significantly lower arterial oxygen pressure compared with nonsmokers. Arterial carbon dioxide values were increased significantly in SHS-exposed patients. Morphine consumption for postoperative analgesia also was increased in patients exposed to SHS compared with that in nonsmokers.

OBJECTIVE: In this study, a north polar tube (Portex® North Polar tube [Ivory PVC Portex tube; Smiths Medical International, Hythe, United Kingdom]) (NPT) and spiral tube (ST) were compared for their ability to provide a nasal airway in patients during maxillofacial surgery. METHODS: Patients who were aged 18 to 65 years with American Society of Anaesthesiologists score 1 to 2 and Mallampati score 1 to 2 were included in the study. The anesthesia technique was standardized in all patients. Patients were divided into 2 groups randomly: the NPT (nâ¯=â¯35) and ST groups (nâ¯=â¯35). Anesthesia was administered with 1% to 2% sevoflurane and a mixture of 50% oxygenâ¯+â¯50% air in both groups. The mean arterial pressure and heart rate values of preinduction; preintubation; and the first, second, third, and fifth minutes of intubation were recorded. Epistaxis, intraoral bleeding, cuff burst, use of Magill pens, duration of intubation, intubation difficulty, laryngeal compression, head position change, and glottic grade were evaluated. RESULTS: There were no significant differences between groups in terms of demographic data (gender, age, height, weight, body mass index, American Society of Anaesthesiologists score, and Mallampati score). Macintosh laryngoscopes were used during intubation in all patients. There was no significant difference between groups in terms of intubation difficulty, duration of intubation, use of Magill pens, and determination of the glottic grade (P > 0.05). Epistaxis was significantly lower in the NPT group than in the ST group (Pâ¯=â¯0.012). Intraoral bleeding was significantly higher in the ST group than in the NPT group (Pâ¯=â¯0.001). During intubation, laryngeal compression (Sellick maneuver) and head position changes were significantly lower in the NPT group than in the ST group (Pâ¯=â¯0.003 and P < 0.001, respectively). There were no significant differences in mean arterial pressure and heart rate between the 2 groups. CONCLUSIONS: We conclude that the NPT was associated with less epistaxis and manipulations such as laryngeal compression and head position changes when compared with the ST during nasotracheal intubation. The velvet-soft polyvinyl chloride material of the NPT appears to be responsible for this advantage.
RESUMEN
BACKGROUND: Colistin (COL) has become the backbone of the treatment of infections due to extensively drug-resistant (XDR) Gram-negative bacteria. The most common restriction to its use is acute kidney injury (AKI). METHODS: We conducted a retrospective cohort study to evaluate risk factors for new-onset AKI in patients receiving COL. The cohort consisted of 198 adults admitted to 9 referral hospitals between January 2010 and October 2012 and treated with intravenous COL for ≥ 72 h. Patients with no pre-existing kidney dysfunction were compared in terms of risk factors and outcomes of AKI graded according to the RIFLE criteria. Logistic regression analysis was used to identify associated risk factors. RESULTS: A total of 198 patients met the inclusion criteria, of whom 167 had no pre-existing kidney dysfunction; the mean patient age was 58.77 (± 18.98) y. Bloodstream infections (34.8%) and ventilator-associated pneumonia (32.3%) were the 2 most common indications for COL use. New-onset AKI developed in 46.1% of the patients, graded as risk (10%), injury (15%), and failure (21%). Patients with high Charlson co-morbidity index (CCI) scores (p = 0.001) and comparatively low initial glomerular filtration rate (GFR) estimations (p < 0.001) were more likely to develop AKI, but older age (p = 0.001; odds ratio 5.199, 95% confidence interval 2.684-10.072) was the major predictor in the multivariate analysis. In-hospital recovery from AKI occurred in 58.1%, within a median of 7 days. CONCLUSIONS: COL-induced nephrotoxicity occurred significantly more often in patients older than 60 y of age and was related to low initial GFR estimations and high CCI scores, which were basically determined by age.

This multicenter, cross-sectional study aimed to determine and examine the privacy awareness and patient rights education of healthcare professionals working in intensive care units (ICUs). The primary purpose of this study was to determine the privacy awareness of healthcare professionals working in the ICU. In addition, the secondary aim was to examine the relationship between patient rights education and awareness scores, as well as to question the need for privacy awareness education. The study population consisted of ICU physicians, nurses, and allied health personnel working in university hospitals, training and research hospitals, state hospitals, and private hospitals in Turkey. The data were collected through a questionnaire prepared by the researchers, including a question set about sociodemographics, a question about patient rights education, and the privacy awareness scale (PAS) scores using online Google Forms. In the results of the study conducted among 569 participants, the mean total PAS score was 38.31 ± 2.54. The PAS score was significantly different according to the occupation. The PAS scores of the nurses were higher than physicians and allied health personnel. The PAS scores differed according to whether the participants had received patient rights education. This study found that nurses were the group with the highest PAS scores among healthcare professionals. In addition, the PAS scores of nurses working in private and training and research hospitals were higher than those of other hospital employees. On the other hand, the lowest scores belonged to university hospitals and receiving patient rights education increased the PAS score of the nurses. This study showed that all enrolled healthcare professionals required in-service training to gain privacy awareness.

Introduction: In this study, we prospectively investigated changes in serum interleukin-6 (IL-6), high-sensitivity C-reactive protein (hsCRP) and full white blood cell (WBC) counts during the diagnosis and treatment of paediatric patients with appendicitis. We also investigated the effects of the COVID-19 pandemic on the diagnosis and treatment processes of paediatric appendicitis patients. Materials and Methods: A non-perforated appendicitis group (n = 110), a perforated appendicitis group (n = 35) and an appendicitis + COVID-19 group (n = 8) were formed. Blood samples were taken upon admission and every day until the three studied parameters returned to normal values. To investigate the effects of the COVID-19 pandemic on paediatric appendicitis patients, the perforated appendicitis rates and the times from the onset of the first symptoms to the operation before and during the pandemic were compared. Results: WBC, IL-6, and hsCRP dropped below the upper limits on the second postoperative day in the non-perforated appendicitis group, four to six days postoperatively in the perforated appendicitis group, and three to six days postoperatively in the appendicitis + COVID-19 group. These parameters were not within normal range in patients who developed complications during follow-up. The time from the onset of abdominal pain to the surgery was significantly longer during than before the pandemic in both the non-perforated appendicitis group and the perforated appendicitis group. Conclusions: Our results show that WBC, IL-6, and hsCRP are useful laboratory parameters that can complete clinical examinations in the diagnosis of appendicitis in paediatric patients and the identification of complications that may develop postoperatively.

INTRODUCTION: In this prospective, randomised study, we compared the effects of the Macintosh, McGRATH MAC, and C-MAC laryngoscopes on intraocular pressure (IOP) and haemodynamics of non-ophthalmic patients during endotracheal intubation. METHODS: One hundred and twenty adult patients undergoing non-ophthalmic surgeries performed in the supine position under general anaesthesia requiring orotracheal intubation were included in this study. The patients were separated randomly and prospectively into 3 groups: Macintosh group (n = 40), McGRATH MAC group (n = 40), and C-MAC group (n = 40). Mean arterial pressure (MAP), heart rate (HR) and IOP of left and right eye were measured at specified times. RESULTS: There were no significant differences with regard to patients characteristics. After intubation, the HR increased significantly in the Macintosh group when compared to the other groups (p = 0.001) and the MAP increased significantly in the Macintosh group when compared to the McGRATH MAC group (p = 0.001) and the C-MAC group (p < 0.001). The IOP values increased in the Macintosh group when compared to the McGRATH MAC group (p < 0.001) and the C-MAC group (p < 0.001) after intubation. Additionally, there was a significant difference between the McGRATH MAC group and C-MAC group in the IOP values of the eyes after intubation (p < 0.001). According to the evaluation within the groups, there were significant differences in all of the groups at all times when compared with the baseline values (p < 0.001). CONCLUSIONS: In this study, we concluded that the C-MAC VL may be preferable when compared to the Macintosh and McGRATH MAC laryngoscopes for use in ophthalmic patients in whom a rise in the IOP is undesirable.

INTRODUCTION: The effects of low-flow anesthesia on cerebral oxygenation in high-risk, morbidly obese patients are not well known. AIM: In this prospective randomized study, we compared the effects of low-flow (0.75 l/min) and normal-flow (1.5 l/min) anesthesia on regional cerebral oxygen saturation (rSO2) and the bispectral index (BIS) in morbidly obese patients undergoing laparoscopic bariatric surgery. MATERIAL AND METHODS: Fifty-two morbidly obese patients undergoing laparoscopic bariatric surgery (sleeve gastrectomy) were enrolled in this study. Patients were randomly allocated to two study groups: low-flow and normal-flow anesthesia groups. Heart rate, mean arterial pressure, peripheral oxygen saturation, end-tidal carbon dioxide, BIS, left and right rSO2, and duration of anesthesia and surgery were recorded. RESULTS: The groups were similar with respect to age, gender, height, weight, body mass index, American Society of Anesthesiology physical status, heart rate, duration of anesthesia, and procedure. Mean arterial pressure and end-tidal carbon dioxide, both before and after insufflation of carbon dioxide and after the reverse Trendelenburg position, were significantly higher in the low-flow group. BIS values and left and right rSO2 during the preoperative and intraoperative periods were similar. Although the difference in right rSO2 between the two groups after awakening from anesthesia was statistically significant, the results of both groups remained within the normal range and were not clinically meaningful. CONCLUSIONS: Low-flow anesthesia is safe regarding hemodynamic and respiratory characteristics, depth of anesthesia, and regional cerebral oxygen saturation in morbidly obese patients undergoing laparoscopic bariatric surgery.
RESUMEN
BACKGROUND: The aim of this study is to determine the efficacy of preemptive analgesia with paracetamol and ibuprofen to reduce the intensity and incidence of headache and myalgia after electroconvulsive therapy (ECT). METHODS: Sixty patients with major depression who were treated with ECT were randomized to receive ECT 3 times a week. The first 3 sessions were included in the study. The patients were divided into 3 groups; Group C (Control, Saline, nâ=â20), Group P (Paracetamol, nâ=â20), and Group I (Ibuprofen, nâ=â20). Demographics, duration of seizure, visual analog scale (VAS) for headache and myalgia and nausea, vomiting and pruritus were evaluated at postoperative 24âhours period. RESULTS: Duration of seizure after ECT was similar in all groups (Pâ=â.148). In the study, heart rate and mean arterial pressure were found to be some changes in some of the sessions. There were no significant differences in any comparison for all groups in all sessions regarding VAS scores for headache and myalgia. Incidence of headache and myalgia in Group I was lower than the other groups (Pâ=â.233, Pâ=â.011, respectively). But, there was no significant difference between the other groups. There was no significant difference in vomiting, intergroups, and intragroup. CONCLUSIONS: The findings of our study indicate that pain intensity of headache and myalgia did not show a significant change between groups and within groups. While pain intensity of myalgia between the groups reached no statistical significance, ibuprofen was significantly lowered the incidence of myalgia at postoperative 24âhours period.

Management of airway in patients who have Coffin-Siris syndrome (CSS) is often problematic because most of these patients have difficult airway. NTI via C-MAC VL is an useful alternative to direct laryngoscope for orotracheal intubation in airway and anesthetic management in a case of CSS. Alternative airway devices should be readily available.
RESUMEN
Epidermolysis bullosa (EB) is a rare disease characterised by vesiculobullous lesions with minimal trauma to the skin and mucous membranes. Bleeding, scar tissue, contractures, oedema and lesions that can spread throughout the body can cause a difficult airway and vascular access in patients with EB. Therefore, anaesthetic management in patients with EB is a major problem even for experienced anaesthesiologists. Herein, we report a case of difficult airway management in a patient diagnosed with severe EB who presented for emergency tracheostomy because of respiratory failure under general anaesthesia.
RESUMEN
BACKGROUND: We compared the analgesic effects of intravenous (IV) paracetamol with that of dexketoprofen on postoperative pain and morphine consumption during the first 24 hour after a lumbar disk surgery. METHODS: This prospective, placebo-controlled, double blind study investigated the analgesic effects of IV paracetamol and dexketoprofen on postoperative pain, morphine consumption, and morphine-related side effects after a lumbar disk surgery. Sixty American Society of Anesthesiologists 1 or 2 status patients scheduled for elective lumbar disk surgery under general anesthesia were included in the study. Patients were treated using patient-controlled analgesia with morphine for 24 hours after a lumbar disk surgery and randomized to receive IV paracetamol 1 g, dexketoprofen 50 mg, or isotonic saline (placebo). The primary endpoint was pain intensity measured by the visual analogue scale, and secondary endpoints were morphine consumption and related side effects. RESULTS: Pain intensity was lower in the dexketoprofen group (P=0.01) but not in the paracetamol group (P=0.21) when compared with the control group. Cumulative morphine consumption and morphine-related side effects did not reveal significant differences between the groups. CONCLUSIONS: The study showed that pain intensity during 24 hours after the lumbar disk surgery was significantly lowered by dexketoprofen, but not with paracetamol, as a supplemental analgesic to morphine patient-controlled analgesia when compared with controls.
