Paediatric flat foot and foot dimension in Central Anatolia.

BACKGROUND: Information on the foot structures of Central Anatolian children is limited. Foot structures of children aged 6-10 years were shown to be different according to sex and increasing age. OBJECTIVE: This study aimed to compare the foot anthropometric values by age and sex and collect the foot anthropometric data to reveal the relationship between pes planus and pes cavus in the arches of children according to age. METHODS: Footprints of 335 children (180 boys and 155 girls) aged 6-10 years were taken by the pedigraph method and evaluated using 18 different parameters. The TFL (Truncated foot length), FL (foot length), Arch Index, Chippaux Smirak Index, Staheli Arc Index, and foot rotation values of the children were examined. To examine the relationship between the parameters, normality values were examined. Independent samples t-test was used to analyze sex differences in terms of foot size and shape. RESULTS: Correlations between other parameters were determined using the correlations analysis method. TFL, metatarsal circumference, and FL were strongly correlated with age in the children. Foot rotation increased with body mass index in the girls compared to that in the boys. According to the evaluation results with the classification made with the Staheli arch index, 63.3% pes planus, 9.8% pes cavus and 27.7% of the normal arch structure were identified. CONCLUSIONS: Planning shoe production accordingly will contribute to the development of healthy feet in children. This article focused on foot structures of in Central Anatolia and to identify early foot deformities in children. This study found that the length of the TFL was smaller in boys than in girls.

The airway device preference may affect the overlapping of the common carotid artery by the internal jugular vein.

BACKGROUND: Anatomical variation in the internal jugular vein (IJV), as well as its small size, tendency to collapse, and proximity to the common carotid artery (CCA) makes central venous cannulation via the IJV a technically challenging procedure, especially in pediatric patients. AIM: We evaluated the effects of laryngeal mask airway insertion and endotracheal intubation (ETT) on the anatomical relationship between the IJV and the CCA in neutral and 40° head away positions. METHOD: After parental consent 92 patients with ASA physical status I-II, aged 0-17, undergoing elective urological surgery were enrolled and divided into two groups according to the airway management device used for anesthesia: Group laryngeal mask airway (n = 63) and Group ETT (n = 29). An ultrasonographic evaluation was performed before and after airway instrumentation at neutral and 40° head rotation. The IJV position in relation to the CCA was noted, and the overlap percentage of the CCA was calculated as the ratio of the CCA length covering by the internal jugular vein to the transverse diameter of the CCA. RESULTS: With no airway device insertion, the position of the IJV was found to be anterolateral to the CCA in the majority of patients (48.8% vs 35.3%, right vs left IJV) in the neutral head position. While there was no significant change in the overlap percentages of the CCA after laryngeal mask airway insertion in the neutral head position [48.71% vs 57.30% for the right IJV (difference in median: -21.20; 95% confidence interval (CI) of difference: -56.92 to 14.52; P = 0.133); 52.54% vs 60.36% for the left IJV (difference in median: -10.3; 95% CI of difference: -41.49 to 20.89; P = 0.128)], it increased significantly in the 40° head away position on both sides [50.11% vs 64.83% for the right IJV (difference in median: -55; 95% CI of difference: -84 to -25.24; P = 0.01); 53.82% vs 71.20% for the left IJV (difference in median: -46; 95% CI of difference: -86.85 to -5.15; P = 0.004)]. However, the overlap percentages of CCA decreased significantly on the right side with patients in a neutral head position (31.23% vs 6.27%, difference in median: 19; 95% CI of difference: -5.68 to 43.68; P = 0.002) and on both sides in the 40° head away position [29.50% vs 16.19%, difference in median: 26; 95% CI of difference: 2.84 to 49.16; P = 0.03 and 47% vs 31.94%, difference in median: 9.50; 95% CI of difference: -40.87 to 59.87; P = 0.03 for the right and left sides, respectively] after ETT insertion. CONCLUSIONS: Laryngeal mask airway with 40° head rotation increases, whereas ETT decreases, the overlap percentage of CCA by IJV. Both head position and airway management methods have an influence on the overlap of the CCA by the IJV in pediatric patients.

Patient Safety during Propofol Sedation before and after Implementation of Capnography Monitoring.

Endoscopic procedures are routinely applied to cancer screening programs and surveillance. The preferred technique is usually deep sedation with propofol being a convenient agent allowing for a quicker patient recovery while maintaining a similar safety profile compared to traditional agents. However, adverse events, including respiratory depression and consequent undesirable cardiovascular side effects, may occur. The goal of this work is to evaluate the patient safety impact of adding capnography during endoscopic procedures under deep propofol sedation. Data were retrospectively collected from patients undergoing deep, procedural sedation for gastrointestinal (GI) endoscopy in October 2019 to January 2021 in a single Turkish university hospital. Included in the analysis were all adult patients classified by the American Society of Anesthesiologists (ASA) as I-IV, who were scheduled for GI endoscopy utilizing propofol alone or in combination. Data on 1840 patients were collected, of whom 1610 (730 pre- and 880 post-capnography implemention) met inclusion criteria. The primary outcome was a change in the composite incidence of mild oxygen desaturation (SpO2 75-90% for <60 s), severe oxygen desaturation (SpO2 < 75% anytime or <90% for >60 s), bradycardia (<60 ppm), and tachycardia (>25% from baseline). Without capnography, on average, 7.5 events of the primary endpoint were observed per 100 procedures and 2.9 with additional capnography monitoring (p < 0.001). A significant reduction was observed for mild oxygen desaturation, with a resulting odds ratio of 0.25 (95% CI 0.14 to 0.46). ASA I patients had the highest difference in combined incidence of any oxygen desaturation of 5.85% in the pre-capnography group and 0.64% in the post-capnography group. Although procedural sedation using propofol is not associated with severe adverse events, the incidence of composite adverse events could be reduced with the addition of capnography monitoring.

Precision Anaesthesia: Advancing Patient-Centered Precision Care Through Repetitive Assessment of PROMs with the Safe Brain Initiative Approach

This article aims to introduce the Safe Brain Initiative (SBI) approach, focusing on collecting and leveraging Patient-Reported Outcome Measures (PROMs) to enhance patient-centred precision anaesthesia and prevent postoperative delirium (POD) and neurocognitive disorders (NCD). The SBI was implemented to systematically address the feedback gap in perioperative care by collecting and analysing real-world data. The initiative focuses on monitoring and preventing POD and NCD, providing effective anaesthesia care, assessing patient and team satisfaction, and evaluating environmental sustainability impact. Based on international guidelines, 18 core recommendations were established to address potential complications and challenges associated with anaesthesia. Preliminary results showed a notable reduction in POD and increased awareness among anaesthesia team members regarding PROMs. The SBI approach demonstrated significant benefits during emergency situations, such as the February 2023 earthquake in Turkey, by providing crucial support and comfort to victims requiring multiple surgical interventions. The SBI presents an innovative, cost-effective, and patient-centred approach to perioperative care. By integrating PROMs and systematic feedback mechanisms, the SBI aims to expedite the advancement of efficient, patient-centered precision perioperative care, improve patient outcomes, and elevate the quality of care. The initiative has shown promising results, and its adoption is growing globally. Collaboration among healthcare providers, researchers, and patients is crucial in shaping the future of anaesthesia practice and further improving patient outcomes. Turkish hospitals are encouraged to join the SBI to benefit from international collaborations and contribute to positive change in perioperative care standards. The SBI project significantly advances precision anaesthesia, emphasising personalised care and patient well-being.

Cost-Effectiveness and Budget Impact of Comprehensive Anemia Management, The First Pillar of Patient Blood Management, on the Turkish Healthcare System.

Purpose: Patient blood management (PBM) is a patient-centered, evidence-based, multidisciplinary approach aimed at optimizing hemoglobin concentration, ensuring the continuity of hemostasis and minimizing blood loss in patients undergoing surgery. The aims of this study were: (1) to explore the cost-effectiveness of comprehensive anemia management, the first pillar of PBM, in non-cardiac and cardiac surgery from the Turkish Social Security Institution's (SSI's) perspective; and (2) to explore the potential budget impact of PBM for coronary artery bypass grafting (CABG) and hip and knee arthroplasty to the SSI. Methods: Cost-effectiveness and budget impact models were developed based on the avoided postoperative adverse events following implementation of the first pillar of PBM for non-cardiac and cardiac surgical patients. The probabilities of adverse events (sepsis with and without pneumonia, renal failure, myocardial infarction and stroke) were taken from a recent meta-analysis and the costs of treating these adverse events to the SSI were estimated through expert views and the use of SSI guidelines. Results: The PBM arm dominated the control arm for both non-cardiac and cardiac surgeries in terms of cost-effectiveness in the simulated cohort of patients and was associated with improved outcomes and lower costs (1768 and 1244 avoided adverse events, and incremental cost reductions for non-cardiac and cardiac surgery of 7504 Turkish lira [TRY] and 6102 TRY, respectively). The budget impact analysis showed that PBM is a potential cost-saving option for the SSI, with savings of up to 196,937,705 TRY (€12,841,697) for hip and knee arthroplasty and 24,642,504 TRY (€1,606,861) for CABG surgery. Conclusion: PBM is a cost-effective option with a potential of cost-saving for cardiac and non-cardiac surgery in Turkey.

Use of simulation to teach in the operating room - Don't let the COVID-19 pandemic interrupt education:an observational clinical trial.

BACKGROUND: Simulation-based education has become the most important part of resident training in anesthesiology, especially during the pandemic. It allows learning the skills and the management of different situations without putting residents in risk of contamination, considering COVID-19 is highly contagious. The hypothesis was that simulation is still associated with improvement of knowledge acquisitions despite the context of the COVID-19 pandemic. METHODS: Residents of anesthesiology and intensive care subjected to an anaphylaxis simulation scenario. Their knowledge levels were assessed by true/false questions before and one month after the simulation session. The STAI test was used to measure anxiety levels before and after the scenario. Data were analyzed statistically using Wilcoxon and McNemar tests. RESULTS: Junior residents (< 2 years) received significantly higher scores in post-training theoretical tests compared to their pre-training scores (79.2 ± 9.6, 84.5 ± 8.2, p = 0.002, n = 21). There was no difference between pre- and post-test scores of seniors (80.2 ± 9, 81.8 ± 10.4, p = 0.3). Pre- and post-anxiety inventory scores were nearly the same and both were in the moderate group (39.8 ± 10.1, 39.3 ± 12.1, p = 0.8). CONCLUSION: Simulation-based education improved the knowledge levels of the residents without raising anxiety levels. Thus, simulation-based training showed its value as an important tool of education during the pandemic, which needs to be further popularized for training at all institutions. Enlightening medical educators about this accomplished teaching method may lead to improved quality of medical education in developing countries and reshape how tomorrow's doctors are trained during pandemics.

What About Compressing the Oesophagus with an Ultrasound Probe for a Modified Sellick Maneuver?

OBJECTIVE: Debates continue about the cricoid pressure, which has been used for many years to prevent gastric aspiration during intubation. Using ultrasound, the effects of this maneuver and alternatives like paralaryngeal pressure are revealed. The aim of this observational study was to determine the effect of paralaryngeal pressure with an ultrasound probe on the esophageal diameter in patients with different body mass indexes and neck circumferences. METHODS: After measuring the neck circumference at the level of the cricoid cartilage, the esophagus was visualized by ultrasonography. Compression was applied medially at a 45° angle toward the vertebral column by the ultrasound probe and esophageal anteroposterior outer diameters were measured. Correlations between body mass index, neck circumference, esophageal diameter, and esophageal diameter change ratio were evaluated with Pearson's r value. RESULTS: One hundred ten volunteers (52 women and 58 men) with mean age 33.7 ± 8.02 years and mean body mass index 25.6 ± 4.65 kg m-2 were recruited. The esophagus was located 78.18% partially to the left, 4.54% completely to the left, 1.81% to the right of the cricoid ring. In 15.45%, esophagus could not be displayed. The mean diameter of the esophagus was 7.6 ± 1.1 mm before pressure and 5.6 ± 0.09 mm after pressure (P < .001). There was no significant correlation between diameter change percentage and body mass index (r=-0.22; P > .05). However, weak correlation was found between diameter change percentage and neck circumference (r=-0.33; P=.016). CONCLUSIONS: Paralaryngeal pressure with an ultrasound probe has the potential to occlude the esophagus and may be effective in all patient groups.

Preliminary report of laryngeal phonation during mechanical ventilation via a new cuffed tracheostomy tube.

OBJECTIVE: To study the safety, efficacy, patient tolerance, and patient satisfaction of the Blom Tracheostomy Tube and Speech Cannula (Pulmodyne, Indianapolis, Indiana), a new device that allows the patient to speak while the tracheostomy tube cuff is fully inflated. METHODS: With 10 tracheostomized mechanically ventilated patients we recorded ventilator settings and physiologic variables at baseline with patient's usual tracheostomy tube, then with the Blom Tracheostomy Tube and the Blom standard (non-speech) cannula, and then during three 30-min trials of the Blom Speech Cannula. During the Blom Speech Cannula trials we assessed the subjects' success in phonation (eg, sentence length and volume). RESULTS: Nine of the 10 subjects achieved sustained audible phonation and were very satisfied with the device. CONCLUSIONS: The Blom Speech Cannula appears to be safe, effective, and well tolerated in tracheostomized mechanically ventilated patients while maintaining full cuff inflation.

Anesthesia for a 16-month-old patient with Prader-Willi syndrome.

Prader-Willi syndrome (PWS) is a rare disorder of chromosome abnormalities in which the paternal genes in chromosome 15 are lacking. The clinical course is characterized by hypotonia, hyperphagia, and morbid obesity. Both general and regional anesthesia in these patients is difficult due to morbid obesity and hypotonia. We report our anesthetic management in a patient with PWS with a body mass index (BMI) of 29.43 kg/m² who underwent orchiopexy and hypospadias repair. The clinical course of the patient was uneventful during the procedure and postoperative period. However, arrangements with a pediatric intensive care setting for the postoperative period are recommended for patients with PWS undergoing surgery.

Peri-operative blood transfusion in elective major surgery: incidence, indications and outcome - an observational multicentre study.

BACKGROUND: Patients' demographic and epidemiological characteristics, local variations in clinicians' knowledge and experience and types of surgery can influence peri-operative transfusion practices. Sharing data on transfusion practices and recipients may improve patients' care and implementation of Patient Blood Management (PBM). MATERIALS AND METHODS: This was a multicentre, prospective, observational, cross-sectional study that included 61 centres. Clinical and transfusion data of patients undergoing major elective surgery were collected; transfusion predictors and patients' outcomes were analysed. RESULTS: Of 6,121 patients, 1,579 (25.8%) received a peri-operative transfusion. A total of 5,812 blood components were transfused: red blood cells (RBC), fresh-frozen plasma and platelets in 1,425 (23.3%), 762 (12.4%) and 88 (1.4%) cases, respectively). Pre-operative anaemia was identified in 2,019 (33%) patients. Half of the RBC units were used by patients in the age group 45-69 years. Specific procedures with the highest RBC use were coronary artery bypass grafting (16.9% of all units) and hip arthroplasty (14.9%). Low haemoglobin concentration was the most common indication for intra-operative RBC transfusion (57%) and plasma and platelet transfusions were mostly initiated for acute bleeding (61.3% and 61.1%, respectively). The RBC transfusion rate in study centres varied from 2% to 72%. RBC transfusion was inappropriate in 99% (n=150/151) of pre-operative, 23% (n=211/926) of intra-operative and 43% (n=308/716) of post-operative RBC transfusion episodes. Pre-operative haemoglobin, increased blood loss, open surgery and duration of surgery were the main independent predictors of intra-operative RBC transfusion. Low pre-operative haemoglobin concentration was independently associated with post-operative pulmonary complications. CONCLUSIONS: These findings identified areas for improvement in peri-operative transfusion practice and PBM implementation in Turkey.

Preoperative diclofenac sodium and tramadol for pain relief after bimaxillary osteotomy.

PURPOSE: The aim of this study was to compare the postoperative analgesic affects of preoperative use of a synthetic opioid tramadol and a nonsteroidal anti-inflammatory drug diclofenac sodium for postoperative pain, with placebo, in patients undergoing bimaxillary osteotomy. PATIENTS AND METHODS: Thirty-six orthognathic surgery patients who underwent both Le Fort I osteotomy in the maxilla and bilateral sagittal split ramus osteotomy in the mandible as bimaxillary osteotomy were randomly allocated into 3 groups via sealed envelope technique. Group T (n = 12), group D (n = 12), and group P (n = 12) received preoperative 50 mg tramadol intramuscularly, 75 mg diclofenac sodium intramuscularly, and saline, respectively. Postoperative pain intensity (visual analog scale, verbal pain score), postoperative opioid consumption with intravenous patient-controlled analgesia, hemodynamic variables, and postoperative complications were compared among the 3 groups. RESULTS: The median number of patient-controlled analgesia demands (n) in group P (34, 28-39) was higher than other groups (group D 14, 11-13; group T 19, 12-25; P = .001). Total tramadol consumption was higher in group P (330 mg, 290-390) compared with group D (260 mg, 190-340; P = .046) and group T (270 mg, 200-330; P = .034). The 3 groups were comparable for the area under the hemodynamic variables time curves. The area under the visual analog scale and verbal pain score curves were lower in group D and group T compared with group P, however, there was no significant difference between group T and group D. CONCLUSIONS: Preoperative diclofenac or tramadol, compared with placebo, effectively decreases postoperative opioid consumption via intravenous patient-controlled analgesia.

Comparison of ProSeal laryngeal mask airway (PLMA) with cuffed and uncuffed endotracheal tubes in infants.

We aimed to compare cuffed and uncuffed endotracheal tubes (ETTs) with ProSealTM laryngeal mask airway (PLMA) in terms of airway security and extubation, starting out from the hypothesis that PLMA will provide alternative airway safety to the endotracheal tubes, and that airway complications will be less observed. After obtaining approval from the local Ethics Committee and parental informed consent, 120 pediatric patients 1-24 months old, American Society of Anesthesiologists physical status I-II, requiring general anesthesia for elective lower abdominal surgery, were randomized into PLMA (Group P, n = 40), cuffed ETT (Group C, n = 40), and uncuffed ETT (Group UC, n = 40) groups. The number of intubation or PLMA insertion attempts was recorded. Each patient's epigastrium was auscultated for gastric insufflation, leak volumes and air leak fractions (leak volume/inspiratory volume) were recorded. Post-operative adverse events related to airway management were also followed up during the first post-operative hour. Demographic and surgical data were similar among the groups. There were significantly fewer airway manipulations in the Group P than in the other groups (p < 0.01), and leak volume and air leak fractions were greater in the Group UC than in the other two groups (p < 0.01). Laryngospasm was significantly lower in the Group P during extubation and within the first minute of post-extubation than in the other groups (p < 0.01). Based on this study, PLMA may be a good alternative to cuffed and uncuffed ETTs for airway management of infants due to the ease of manipulation and lower incidence of laryngospasm.

Influence of Different Doses of Ketamine on Intubating Conditions during a Rapid Sequence Induction and Intubation Model.

OBJECTIVE: This prospective, randomized, double-blinded study aimed to compare the effects of three different doses of ketamine or lidocaine on intubating conditions and haemodynamics in a rapid-sequence induction model with 3 mg kg(-1) propofol and 0.6 mg kg(-1) rocuronium. METHODS: A total of 128 ASA I-III patients who were scheduled for elective surgery were randomized in the following five groups: Group 1 (n=24), 1 mg kg(-1) lidocaine+3 mg kg(-1) propofol+0.6 mg kg(-1) rocuronium; Group 2 (n=23), 0.1 mg kg(-1) ketamine+3 mg kg(-1) propofol+0.6 mg kg(-1) rocuronium; Group 3 (n=29), 0.3 mg kg(-1) ketamine+3 mg kg(-1) propofol+0.6 mg kg(-1) rocuronium; Group 4 (n=26), 0.5 mg kg(-1) ketamine+3 mg kg(-1) propofol+0.6 mg kg(-1) rocuronium and Group 5 (n=26), 3 mg kg(-1) propofol+0.6 mg kg(-1) rocuronium+saline as placebo. After preoxygenation, induction was performed with the assigned combination, and intubation was initiated after 60 s. The time to intubation, intubation score (Viby-Mogensen score) and haemodynamic data were recorded. Postoperative hoarseness, sore throat and hallucination incidences were followed up. RESULTS: Demographic, time to intubation and haemodynamic data were comparable among groups. Group 4 [13.5 (4-14)] revealed a higher intubation score then groups 1, 2 and 5 [12 (3-14), 11 (2-14) and 9.5 (0-13) and p=0.026, p=0.001 and p=0.000001, respectively]. Groups 3 [13 (4-14)] and 4 [13.5 (4-14)] had similar intubation scores. Side effects were comparable among all groups. CONCLUSION: The combination of 0.5 mg kg(-1) ketamine and 0.6 mg kg(-1) rocuronium along with propofol improves intubation conditions in a stimulated rapid-sequence induction model.

A comparison of two different doses of morphine added to spinal bupivacaine for inguinal hernia repair.

BACKGROUND AND OBJECTIVES: The aim of this study was to compare the effects of two different doses of intrathecal morphine on postoperative analgesia, postoperative first mobilization and urination times and the severity of side effects. METHODS: After Institutional Ethical Committee approval, 48 ASA I-II patients were enrolled in this randomized double-blinded study. Spinal anesthesia was performed with 0.1mg (Group I, n=22) or 0.4mg (Group II, n=26) ITM in addition to 7.5mg heavy bupivacaine. The first analgesic requirement, first mobilization and voiding times, and postoperative side effects were recorded. Statistical analyses were performed using SPSS 15.0 and p<0.05 was considered as statistically significant. The numeric data were analyzed by the t-test and presented as mean±SD. Categorical data were analyzed with the chi-square test and expressed as number of patients and percentage. RESULTS: Demographic data were similar among groups. There were no differences related to postoperative pain, first analgesic requirements, and first mobilization and first voiding times. The only difference between two groups was the vomiting incidence. In Group II 23% (n=6) of the patients had vomiting during the first postoperative 24h compared to 0% in Group I (p=0.025). CONCLUSION: For inguinal hernia repairs, the dose of 0.1mg of ITM provides comparable postoperative analgesia with a dose of 0.4mg, with significantly lower vomiting incidence when combined with low dose heavy bupivacaine.

CHALLENGES OF OBSTETRIC ANESTHESIA: DIFFICULT LARYNGEAL VISUALIZATION.

Obstetric anesthesia is one of the high risk subspecialties of anesthesia practice. Anesthesia related complications are the sixth leading cause of maternal mortality. Difficult or failed intubation following induction of general anesthesia for CS remains the major contributory factor to anesthesia-related maternal complications. The airway management of obstetric patients is a challenging issue for several reasons. Anatomic and physiologic changes related to pregnancy may increase the difficult and failed intubation rates compared to the general surgical population. Proper evaluation of the airway anatomy and airway structures is vital to prevent airway management related catastrophes. In addition to basic airway and intubation equipment, each anesthesia department must have difficult intubation equipment cart including fiber optic laryngoscope, video laryngoscopes, and different types of laryngeal masks. It is essential that all anesthesiologists have a preconceived and well thought-out algorithm and emergency airway equipment to deal with airway emergencies during difficult or failed intubation of a parturient.

Does ultrasonographic volume of the thyroid gland correlate with difficult intubation? An observational study.

BACKGROUND AND OBJECTIVES: Preoperative ultrasonographic evaluation of the thyroid gland done by surgeons could let us foresee airway management challenges. The aim of this observational study was to evaluate the effects of thyroid-related parameters assessed preoperatively by surgeons via ultrasonography and chest X-ray on intubation conditions. METHODS: Fifty patients undergoing thyroid surgery were enrolled. Thyromental distance, Mallampati score, neck circumference and range of neck movement were evaluated before the operation. Thyroid volume, signs of invasion or compression and tracheal deviation on chest X-ray were also noted. The intubation conditions were assessed with Cormack and Lehane score and the intubation difficulty scale. Statistical analyses were done with SPSS 15.0 software. RESULTS: The mean thyroid volume of the patients was 26.38 ± 14 mL. The median intubation difficulty scale was 1 (0-2). Thyromental distance (p = 0.011; r = 0.36; 95% CI 0.582-0.088), Mallampati score (p = 0.041; r = 0.29; 95% CI 0.013-0.526), compression or invasion signs (p = 0.041; r = 0.28; 95% CI 0.006-0.521) and tracheal deviation on chest X-ray (p = 0.041; r = 0.52; 95% CI 0.268-0.702) were correlated with intubation difficulty scale. Also patients were classified into two groups related to their intubation difficulty scale (Group I, n = 19: intubation difficulty scale = 0; Group II, n = 31: 1< intubation difficulty scale ≤ 5) and difficult intubation predictors and thyroid-related parameters were compared. Only Mallampati score was significantly different between groups (p = 0.025). CONCLUSION: The thyroid volume is not associated with difficult intubation. However clinical assessment parameters may predict difficult intubation.

Thyromental distance (p=0.011; r=0.36; 95% CI 0.582-0.088), Mallampati score (p=0.041; r=0.29; 95% CI 0.013-0.526), compression or invasion signs (p=0.041; r=0.28; 95% CI 0.006-0.521) and tracheal deviation on chest X-ray (p=0.041; r=0.52; 95% CI 0.268-0.702) were correlated with intubation difficulty scale. Also patients were classified into two groups related to their intubation difficulty scale (Group I, n=19: intubation difficulty scale=0; Group II, n=31: 1

Comparison of intravenous morphine, epidural morphine with/without bupivacaine or ropivacaine in postthoracotomy pain management with patient controlled analgesia technique.

BACKGROUND AND OBJECTIVES: The aim of this randomized, double-blinded, prospective study was to determine the effectiveness and side effects of intravenous or epidural use of morphine, bupivacaine or ropivacaine on post-thoracotomy pain management. METHODS: Sixty patients undergoing elective thoracotomy procedure were randomly allocated into 4 groups by the sealed envelope technique. Group IVM, EM, EMB and EMR received patient controlled intravenous morphine, and epidural morphine, morphine-bupivacaine and morphine-ropivacaine, respectively. Perioperative heart rate, blood pressure and oxygen saturation and postoperative pain at rest and during cough, side effects and rescue analgesic requirements were recorded at the 30(th) and 60(th) minutes and the 2(nd), 4(th), 6(th), 12(th), 24(th), 36(th), 48(th), and 72(nd) hour. RESULTS: Diclofenac sodium requirement during the study was lower in Group EM. Area under VAS-time curve was lower in Group EM compared to Group IVM, but similar to Group EMB and EMR. Pain scores at rest were higher at the 12, 24, 36, and 48(th) hour in Group IVM compared to Group EM. Pain scores at rest were higher at the 30(th) and 60(th) minutes in Group EM and Group IVM compared to Group EMB. Pain scores during cough at the 30(th) minute were higher in Group EM compared to Group EMB. There was no difference between Group IVM and Group EMR. CONCLUSIONS: Morphine used at the epidural route was found more effective than the intravenous route. While Group EM was more effective in the late period of postoperative, Group EMB was more effective in the early period. We concluded that epidural morphine was the most effective and preferred one.
