RESUMO
The outbreak of coronavirus disease (COVID-19) that started in Wuhan, China, has spread to 210 countries, infecting 2,726,274 patients and causing 191,075 deaths by April 24, 2020, and has turned into a global threat. Although various measures have been taken to stop human-to-human transmission in many countries, health care workers are in the high-risk zone for transmission as they deliver patient care. It is evident that anaesthesiologists will keep encountering patients with confirmed or suspected COVID-19 infection who will undergo emergency surgeries. Anaesthesiologists carry a higher risk of being infected during aerosol-creating procedures, hence appropriate protective measures should be taken, both during preoperative evaluation and management anaesthesia. Anaesthesia management of patients with COVID-19 also is a challenge for anaesthesiologists as it is an infection that may affect not only the respiratory system but also other vital organs. The aims of this review are to provide prudent safety measures to protect anaesthesiologists and other health care workers in the operating theatre and recommendations or the safest anaesthesia management of patients with suspected or confirmed COVID-19 undergoing surgery.
RESUMO
BACKGROUND: Various techniques are used to detect intraoperative bleeding points in thyroid surgery. We aimed to assess the effect of increasing peak airway pressure to 30, 40 and 50 cm H2O manually in detecting intraoperative bleeding points. METHODS: One hundred and 34 patients scheduled for total thyroidectomy were included to this prospective randomised controlled clinical study. We randomly assigned patients to increase peak airway pressure to 30, 40 and 50 cm H2O manually intraoperatively just before surgical closure during hemostasis control. The primary endpoint was the rate of bleeding points detected by the surgeon during peak airway pressure increase. RESULTS: The rate of detection of the bleeding points was higher in 50 cm H2O Group than the other two groups (15.9 vs 25.5 vs 40%, P = 0.030), after pressure administration, the HR, SpO2, and P peak were similar between groups (P = 0.125, 0.196, 0.187, respectively). The median duration of the bleeding point detection after the pressure application was 21.82 s in 30 cm H2O, 25 s in 40 cm H2O, and 22.50 s in 50 cm H2O groups. Postoperative subcutaneous hematomas or hemorrhages requiring surgery were not seen in any patient. CONCLUSIONS: Manually increasing peak airway pressure to 50 cm H2O during at least 22.50 s may be used as an alternative way to detect intraoperative bleeding points in thyroid surgery.

Background and Objectives: Percutaneous nephrolithotomy (PCNL) is a minimally invasive procedure for removing kidney stones, but patients still suffer from moderate postoperative pain. The aim of this study is to evaluate the perioperative analgesic effect of ultrasound-guided subcostal transversus abdominis plane (TAP) block performed before PCNL procedure. Materials and Methods: Patients scheduled for elective PCNL were randomized into two groups: Group TAP and Group IV. General anesthesia was induced with propofol, fentanyl, and rocuronium and maintained with sevoflurane, fentanyl, and rocuronium. Unilateral ultrasound-guided TAP block was performed with total of 30 mL volume of local anesthetic solution (20 mL bupivacaine 0.125% plus 10 mL lidocaine 1%) after intubation but before surgery to the Group TAP patients. Paracetamol 1 g was given to the Group IV. Tramadol 100 mg and morphine IV-patient-controlled analgesia were applied to both groups. Perioperative fentanyl consumption, postoperative verbal analog scale (VAS), morphine consumption, and additional analgesic drug requirement were assessed. Chi square with Yates correction and Mann-Whitney U tests were used for statistical analysis. Results: Eighty patients were assessed for enrollment. One patient developed septicemia at the recovery room so data of 79 patients were collected for statistical analysis. Total morphine consumption at 48th hour after the surgery was lower at Group TAP (p = 0.022). Perioperative fentanyl consumption was lower at Group TAP (p < 0.001). Additional analgesic requirement and VAS were comparable between groups. Conclusions: Preemptive unilateral ultrasound-guided subcostal TAP block decreases perioperative fentanyl and postoperative total morphine consumption in PCNL patients compared to IV analgesic management.

We anticipated that bilateral Erector spinae plane (ESP) block, which was applied in 10 patients starting from lower thoracic levels (T9) might provide effective postoperative analgesia in open abdominal hysterectomies. In addition, we aimed to obtain anatomic observation of the local anaesthetic (LA) spread in the ESP block by injecting methylene blue on 4 cadavers. All the patients had excellent pain relief. There was an extensive spread to the erector spinae muscle (ESM) involving several segmental levels on cadavers. We observed the spread of dye on the ventral and dorsal rami in the paravertebral space and as an additional finding, the dye had extended to the canal vertebralis. There was a spread of dye on the dura mater. ESP block can be used with new indications and it is an effective technique for major abdominal surgery when is applied to the lower vertebral levels. Randomized controlled trials are required to explore the clinical implications of our findings.
RESUMO
PURPOSE: Mask ventilation and laryngoscopy can be challenging in morbidly obese patients because of excessive fat tissue. There are studies suggesting that neck circumference is associated with difficult mask ventilation, difficult laryngoscopy, and difficult intubation. The primary aim of our study is to evaluate predictive value of neck circumference for difficult mask ventilation and difficult laryngoscopy in female and male morbidly obese patients separately. METHODS: This observational cross-sectional study was performed in the period between March 2015 and December 2015. One hundred and twenty (37 male and 83 female) patients undergoing elective surgery were included. Neck circumference, BMI, Mallampati scores, neck movements, dentition, upper lip bite test, breast, thorax, waist, hip circumferences, mouth opening, and sternomental and thyromental distances were evaluated preoperatively. Mask ventilation was graded using four-grade classification. Laryngoscopy was evaluated by Cormack Lehane score. RESULTS: The incidence of difficult mask ventilation was 13.5% in male and 3.6% in female patients. Mouth opening ≤ 6.5 cm and inadequate flexion were found as significant predictors for difficult mask ventilation in male patients. The incidence of difficult laryngoscopy was 10.8% in male and 4.8% in female patients. Mallampati score > II was found as a significant predictor for difficult laryngoscopy in both male and female patients. Sternomental distance ≤ 16 cm and inadequate flexion were also significant predictors for difficult laryngoscopy in male patients. Neck circumference was not found statistically significant predictor for difficult mask ventilation and laryngoscopy in morbidly obese patients in our study. CONCLUSION: Neck circumference is not a statistically significant predictor for difficult mask ventilation and laryngoscopy in morbidly Turkish obese male and female patients.

Antecedentes. Durante una esofagoscopía en niños, pueden ocurrir complicaciones durante la dilatación. Identificamos alteraciones cardiorrespiratorias durante la esofagoscopía con o sin dilatación con globo y las complicaciones posoperatorias, en niños con anestesia. Métodos. Estudio prospectivo, observacional de procedimientos endoscópicos en niños de 0-16 años. Se dividieron en dos grupos: con endoscopía-dilatación (Grupo ED) y dilatación con globo por estenosis esofágica, y con endoscopía sin dilatación (Grupo E): endoscopía diagnóstica, esofagoscopía de control o escleroterapia. Registramos parámetros hemodinámicos y ventilatorios y las complicaciones durante la endoscopía, la dilatación y el seguimiento de dos horas en la sala de recuperación. Resultados. Incluimos 102 procedimientos en 60 pacientes. La presión inspiratoria máxima (PIM) aumentó significativamente en ambos grupos (p < 0,001) y aumentó significativamente durante el procedimiento en el grupo ED (p < 0,001). La diferencia en la PIM antes y después de la endoscopía se correlacionó negativamente en ambos grupos. Al subdividir los grupos según el punto de corte de 2 años para comparar la diferencia en la PIM antes y después de la endoscopía, la PIM aumentó de manera estadísticamente significativa en ambos grupos en los menores de 2 años. En el grupo ED, la frecuencia cardíaca aumentó estadísticamente significativa (p < 0,001). Conclusión. Durante la endoscopía, la PIM aumentó en niños con o sin dilatación con globo, especialmente en el grupo ED, y fue mayor en los niños más pequeños. Es necesario observar y tratar atentamente las complicaciones cardiorrespiratorias graves durante la dilatación con globo y con anestesia general.
Background. Complications can occur during esophagoscopy as a result of applied procedure in children, especially during dilation techic. Our aim was to identify cardio-respiratory alterations during esophagoscopy with or without baloon dilation under anesthesia in children, and to investigate the postoperative complications. Methods. Prospective, observational study of endoscopic procedures in patients 0-16 years. The patients were divided into two groups: the endoscopy-dilation group (Group ED: endoscopy and balloon dilation due to esophageal stricture) and endoscopy without dilation (Group E: endoscopy for diagnostic reasons, control esophagoscopy or sclerotherapy). Hemodynamic and ventilatory parameters alterations and complications during endoscopy, dilation and two-hours follow-up time in the postoperative recovery room were recorded. Results. 102 procedures in 60 patients were included. Peak inspiratory pressure (PIP) values significantly increased after endoscopy in both groups (p<0.001). There was a significant increase in mean PIP values in the dilation group during the procedure (p<0,001). The difference in PIP values before and after the endoscopy was negatively correlated with age in both groups. When the groups were subdivided taking two years of age as a cut-off point in comparing PIP difference before-after endoscopy, PIP increase was statistically significant in both groups under two-years old. In the dilation group, statistically significant increase of HR was detected during the procedure (p<0,001). Conclusion. During endoscopy PIP increased in patients with or without baloon dilation especially in the dilation group. PIP increase was higher in younger children. Severe respiratory and cardiovascular complications during balloon dilation under general anesthesia should be carefully observed and managed.

OBJECTIVES: Although osmotic diuresis with mannitol is commonly used to provide brain relaxation, there is no consensus regarding its optimal dose and combination with loop diuretics. The aim of the present study is to evaluate the effects of mannitol and combination of furosemide with different doses of mannitol on brain relaxation and on blood electrolytes, lactate level, urine output, fluid balance and blood osmolarity in patients undergoing supratentorial tumor surgery. PATIENTS AND METHODS: This prospective, randomized, double blind, placebo-controlled study included 51 patients (ASA I-III) scheduled for elective supratentorial craniotomy. Different doses and combinations of diuretics were administered after the bone flap removal. The Group 1 received mannitol at 0.5gkg-1 and furosemide at 0.5mgkg-1, the Group 2 received mannitol at 1gkg-1 and furosemide at 0.5mgkg-1, and the Group 3 received mannitol at 0.5gkg-1 and placebo. The primary end-point of the present study is to evaluate the effects of mannitol and combination of furosemide with different doses of mannitol on brain relaxation and the secondary end-points are to evaluate their effects on blood electrolytes, lactate level, urine output, fluid balance and blood osmolarity. RESULTS: This study shows that mannitol alone (0.5gkg-1), and the combinations of furosemide (0.5mgkg-1) with different doses of mannitol (0.5gkg-1-1gkg-1) provides adequate brain relaxation. However, administration of furosemide with low or high doses of mannitol may cause reduction in the sodium and chloride levels as well as rise in the lactate level. Moreover it may cause high urine output and negative intra-operative fluid balance. CONCLUSION: Administration of 0.5gkg-1 mannitol provides adequate brain relaxation without causing systemic side effects in patients undergoing supratentorial tumor surgery. This study is registered to clinical trials (Clinical Trials.gov identifier NCT02712476).

BACKGROUND: The effectiveness of the TAP block in children has been well characterized in literature. However, there are only few reports about TAP block in the neonates and low birth weight groups. This is a retrospective observational analysis of ultrasound - assisted TAP blocks in neonates and young infants. The aim of this study to analyze retrospectively the analgesic effectiveness of TAP block in neonates and infants undergoing abdominal and inguinal surgeries. METHODS: Thirty-four cases of neonates and infants with (whom) applied TAP block were retrospectively analyzed. The TAP block was performed postoperatively in supraumbilical surgeries and preoperatively in infraumbilical surgeries. The TAP block was applied with 0.8 ml/kg-1 of 0.25% bupivacaine in unilateral approach and 1.6 mlkg-1 of 0.125% bupivacaine in bilateral approach. The CRIES Pain Scale was used for postoperative pain measurement of neonates. RESULTS: The patient's age ranged from 2 to 88 day-old with a mean (SD) of 36.2(24.2). Eleven of them were premature babies. The weight ranged from 1.6 to 5.8 with a mean (SD) of 3.7kg (1.1). Twenty-nine patients were extubated at the end of the surgery and the other patients within 12 hours. 67.7% infants required no additional postoperative analgesic in 24 hours and none of them required narcotic analgesics. CONCLUSIONS: Our conclusion is that the use of TAP blocks results in low analgesic requirements and a low incidence of postoperative intubation and mechanical ventilation in neonates and infants. It should be considered in this age group of child for postoperative analgesia.
RESUMO
BACKGROUND AND OBJECTIVES: Postoperative pain management after hypospadias surgery is often challenging. Caudal block is used for analgesia but has limitations. This study compares the analgesic efficiency of pudendal block with that of caudal block in pediatric patients undergoing hypospadias repair surgery. METHODS: This prospective, double-blind, randomized, controlled study enrolled 84 patients receiving pudendal block or caudal block before hypospadias surgery. In the pudendal group, the pudendal nerve was identified using a nerve stimulator, and the block consisted of 0.25% bupivacaine 0.5 mL/kg. In the caudal group, the caudal block used 0.2% bupivacaine 1 mL/kg. Our primary outcome was pain intensity within 24 hours postoperatively. The trial was registered at ClinicalTrials.gov (number: NCT02390388). RESULTS: For the primary outcome, patients in the pudendal group had lower postoperative pain intensity when compared with the caudal group (P < 0.001). Three patients in the pudendal group and all of the patients in the caudal group needed additional analgesia within 24 hours after the surgery (P < 0.001). The family satisfaction rate was significantly higher in the pudendal group (P < 0.001). CONCLUSIONS: For the pudendal group, the pain scores for the first 24 hours after the surgery were significantly lower and the duration of analgesia was longer.

OBJECTIVES: The prevalence of moderate to severe pain is high in patients following craniotomy. Although optimal analgesic therapy is mandatory, there is no consensus regarding analgesic regimen for post-craniotomy pain exists. This study aimed to investigate the effects of morphine and non-opioid analgesics on postcraniotomy pain. PATIENTS AND METHODS: This prospective, randomized, double blind, placebo controlled study included eighty three patients (ASA 1, II, and III) scheduled for elective supratentorial craniotomy. Intravenous dexketoprofen, paracetamol and metamizol were investigated for their effects on pain intensity, morphine consumption and morphine related side effects during the first 24h following supratentorial craniotomy. Patients were treated with morphine based patient controlled analgesia (PCA) for 24h following surgery and randomized to receive supplemental IV dexketoprofen 50mg, paracetamol 1g, metamizol 1g or placebo. The primary endpoint was pain intensity, secondary endpoint was the effects on morphine consumption and related side effects. RESULTS: When the whole study period was analyzed with repeated measures of ANOVA, the pain intensity, cumulative morphine consumption and related side effects were not different among the groups (p>0.05). CONCLUSION: This study showed that the use of morphine based PCA prevented moderate to severe postoperative pain without causing any life threatening side effects in patients undergoing supratentorial craniotomy with a vigilant follow up during postoperative 24h. Although we could not demonstrate statistically significant effect of supplemental analgesics on morphine consumption, it was lower in dexketoprofen and metamizol groups than control group.

STUDY OBJECTIVE: To compare the analgesic efficacy of ultrasound-assisted transversus abdominis plane (TAP) block and wound infiltration during the first postoperative 24hours. DESIGN: A prospective, observer-blinded, randomized, and controlled study SETTING: Operating room of a university hospital. PATIENTS: Forty patients received a TAP block (TAP group) and 40 patients received wound infiltration (INF group) at the end of the surgery. INTERVENTIONS: Patients were randomized to receive a TAP block or wound infiltration. Postoperative analgesics were administered on request and selected based on pain severity. MEASUREMENTS: Pain scores, analgesic drug requirement, and side effects were observed for 24hours. MAIN RESULTS: Postoperative pain scores were lower in TAP group compared to INF group (P<.001). Analgesic consumption was significantly higher at the 5th minute and 1st, 6th, and 12th hours in the INF group (P<.001). The frequency of additional analgesic use in home and the total analgesic used during the postoperative 24hours were significantly higher in INF group (P<.001). Side effects were lower in the TAP group. Parent's satisfaction scores were higher in TAP group. CONCLUSION: Transversus abdominis plane block is effective method with convenient technique, drug dosage, and volume in pediatric patients undergoing inguinal hernia surgery.

PURPOSE: The hypothesis of our study is that during anesthesia, administration of 80 % oxygen concentration increases oxidative stress more than 40 % oxygen. METHODS: Forty ASA I-II patients were included in a randomized, single-blind study. Expiratory tidal volumes (ETV) were measured before induction and after extubation. After ventilation with 0.8 FiO2 and intubation, mini-bronchoalveolar lavage (mini-BAL), arterial blood gas (ABG), and blood samples were taken. Patients were randomly assigned to receive 0.8 (group I) or 0.4 (group II) FiO2 during management. Before extubation, mini-BAL, ABG, blood samples were taken. PaO2/FiO2, lactate, malondialdehyde (MDA), protein carbonyl (PCO), superoxide dismutase (SOD), total sulfhydryl (T-SH), non-protein sulfhydryl (NPSH), and protein sulfhydryl (PSH) were measured. In both groups, mean arterial pressure and heart rate values were recorded with 30-min intervals. RESULTS: ETV values were higher in group II after extubation. PaO2/FiO2 values were higher in group II after extubation compared to group I. In both groups, plasma PCO, SOD, and T-SH levels increased significantly before extubation, whereas the increase in MDA was not significant between groups. Plasma PCO, T-SH, and lactate levels were higher in group I, and plasma SOD, and PSH were higher in group I before extubation. In both groups, MDA, SOD, T-SH, and NPSH levels in mini-BAL increased significantly before extubation. Between-group comparisons, PCO, T-SH, PSH, and NPSH were significantly higher in the BAL samples of group II, and MDA levels were higher in group I. CONCLUSIONS: We found that 80 % FiO2 decreased ETV and PaO2/FiO2 and increased lactate levels and oxidative stress more, inhibiting antioxidant response compared to 40 % FiO2.

BACKGROUND: To assess whether patient comfort could be increased by adding procedural sedation and analgesia (PSAA) to periprostatic nerve block (PNB) in patients undergoing transrectal ultrasound-guided prostatic biopsy (TRUS-PB). METHODS: This was a prospective, randomized (1:2) trial comparing PNB with the combination of PSAA+PNB in patients undergoing TRUS-PB. PNB was achieved by using lidocaine gel and lidocaine and bipuvacaine infiltration. PSAA-treated patients received midazolam and remifentanil. All biopsies were standardized and performed in a fully equipped endourology suite. PSAA was delivered by an anesthesiology nurse in the presence and availability of an anesthesiologist. An orally administered numeric scale of 0-10 was used to assess the patient's pain, and a visual scale of 0-4 was used to quantify their satisfaction. Pain and satisfaction scores were compared between the groups. RESULTS: Data on 331 patients were analyzed: 235 received PNB, and 96 received PSAA+PNB. Distribution within the groups by age, prostate-specific antigen serum levels, prostate volume, and number of cores obtained was similar. Airway insertion was required in 4 of 96 patients in PSAA+PNB arm (4%), with no other complications related to sedation. The average pain level was significantly lower in the PSAA+PNB group than it was in the PNB group (0.88 versus 1.31; p = 0.008). The satisfaction level was high (3.5) and alike in the two groups; however, significantly more patients reported a perfect score of 4 in the PSAA+PNB arm (p = 0.03). CONCLUSIONS: PSAA with midazolam and remifentanil used as an adjunct to the standard PNB is safe and effective during TRUS-PB. Patients undergoing PSAA in addition to PNB experienced significantly less pain and higher satisfaction scores than did those given PNB alone.

OBJECTIVE: We aimed to compare the first 24-hour postoperative analgesic efficiency of ultrasound (USG)-assisted transversus abdominis plane (TAP) block to IV morphine patient-controlled analgesia (PCA) in patients undergoing lower abdominal surgery. METHODS: Fifty ASA I-III patients were included into this randomised, prospective clinical study. At end of surgery, Group 1 received 1 mg kg(-1) 0.5% bupivacaine and 1 mg kg(-1) 1% lidocaine in a 30-mL volume during TAP-block. Group 2 received 1 mg kg(-1) tramadol IV 10 minutes before extubation, and PCA was started with 1 mL morphine IV at a concentration of 1 mg kg(-1) and a 10-min lock time. Visual analogue scale (VAS), heart rate (HR), respiratory rate, peripheral oxygen saturation (SpO2), additional analgesic need and nausea-vomiting at the postoperative 30(th) minute and 1, 2, 3, 6, 12, and 24 hours were evaluated. In both groups, when VAS values were >4, patients were given 1 mg kg(-1) tramadol IV in first evaluation at the 30(th) minute or 15 mg kg(-1) paracetamol at other evaluations. RESULTS: No difference was observed between groups in terms of VAS values. No difference was observed in terms of HR in the within-group comparison, but Group 1 HR values were lower compared to Group 2 (p<0.01). No difference was observed in additional analgesic need at any times. Nausea-vomiting score was higher in Group 2 in the between-group comparison at the 30(th) minute (p<0.04), but no difference was observed after the 1(st) hour. CONCLUSION: Transversus abdominis plane block is effective as IV morphine-PCA in postoperative pain therapy in lower abdominal surgery, when given in a 30-mL volume. It may be preferable to IV-PCA, as the analgesic effect starts earlier and decreases the systemic effect of the morphine used in PCA.
RESUMO
Here, we report anaesthesia management and the successful use of total intravenous anaesthesia and sugammadex in a patient with Ullrich's disease. Propofol and remifentanyl infusion was used for anaesthesia. After the end of the surgery, when the train-of-four value was 0%, 4 mg kg(-1) sugammadex was administered, and the patient was successfully extubated after 36 s. No adverse effects or safety concerns were observed. In conclusion, we suggest that the use of propofol infusion to avoid the use of inhalation anaesthetics and the use of sugammadex for the reversal of the effects of rocuronium is safe in patients with Ullrich's disease.
RESUMO
PURPOSE: Right internal jugular vein (RIJV) catheterisation is a common procedure in patients undergoing surgery. We aimed to compare diameters and the cross-sectional area (CSA) of the RIJV when the head is in a neutral or 30-degree rotated position during mechanical ventilation in various modes and spontaneous ventilation. METHODS: Thirty patients undergoing surgery were included in the study. In each patient, still ultrasound images of the vena jugularis interna were taken with the head in a neutral position and with the neck rotated 30 degrees to the left, first under spontaneous ventilation (group S), then after the induction of anaesthesia under volume-controlled ventilation (group V) and under pressure-controlled ventilation (group P). The six still images were evaluated in terms of transverse and anteroposterior diameters and CSA. RESULTS: Diameters in the neutral and lateral positions in group S were significantly smaller than in group P and group V (neutral transverse p = 0.01, anteroposterior p = 0.041, rotated transverse p = 0.01, anteroposterior p = 0.03). The CSAs of the RIJV in the neutral and lateral positions were significantly larger in group P and group V than Group S (lateral CSA p = 0.001, neutral CSA p = 0.002). CSA increased significantly only in group P when the head was rotated 30 degrees laterally (p = 0.002). CONCLUSION: We conclude that both pressure-controlled and volume-controlled mechanical ventilation have similar effects on the CSA and diameters of the RIJV. Positioning of the head with a 30-degree rotation laterally has different effects on CSA depending on the ventilation mode used. A neutral position should be preferred with spontaneous ventilation whereas 30 degree rotation should be preferred in patients under pressure-controlled and volume-controlled ventilation.
