The use of STOP-BANG questionnaire and other difficult airway determinants in difficult airway prediction and correlation.

BACKGROUND: The primary objective of this study was to evaluate the use of STOP-BANG questionnaire in prediction of difficult airway. The secondary aim of this study is to evaluate the correlation of the questionnaire and other difficult airway determinant tests in predicting difficult airway. METHODS: Two hundred American Society of Anesthesiologists' Status I, II, and III patients under general anesthesia were enrolled in this prospective randomized study. Patients' age, height, body weight, body mass index, neck circumference, inter-incisor distance when the mouth is fully open, sternomental and thyromental distance, mandibular length, neck length, biting the upper lip, STOP-BANG score, and Mallampati and Cormack-Lehane (C-L) grades were recorded. The first thing we want to find is to determine the usability of the STOP-BANG questionnaire as an indicator of the difficult airway. Comparing difficult airway with the other parameters was secondary objectives. The patients were divided into two groups as difficult and easy intubation with difficult and easy facial mask ventilation. The data were analyzed using an SPSS statistics 16.0 program. Statistical analysis was performed using, Chi-square and Spearman correlation analysis test. RESULTS: Forty-five out of 200 patients had difficulty in intubation and 73 out of them had difficulty in mask ventilation. Between difficult airway and high STOP-BANG score was a moderate positive correlation (p<0.05). Furthermore, unnatural dental status, greater head circumference, greater neck circumference, Mallampati, and C-L classification were significantly positive correlated with a difficult airway (p<0.05). CONCLUSION: In our study, the STOP-BANG questionnaire was found to be important in predicting the difficult airway and this test was found to be usable like other difficult airway parameters.

The Impact of Surgical Procedures During Septorhinoplasty on the Intraoperative Pain Response.

BACKGROUND: During septorhinoplasty, many different surgical procedures are employed to bring the nose to the desired shape and solve breathing complaints. As a matter of course, intraoperative pain response occurs due to these procedures. OBJECTIVES: With this study, the authors aimed to evaluate the intraoperative pain formed during septorhinoplasty surgery with numerical values and to determine which stage of surgery is more painful. METHODS: Between April 2019 and March 2020, a total of 30 female patients who were planned to undergo septorhinoplasty were included in this prospective study. Standard anesthesia and analgesia were applied to all patients. During surgery, state entropy measure was utilized to evaluate the depth of anesthesia, and Surgical Pleth Index was employed to evaluate the response of the central nervous system to pain "nociception." RESULTS: The age of the patients ranged from 18 to 42 years (average, 25.3 ±â€…6.1 years). The average value of state entropy recorded during the surgery for all patients was found to be 45.43 ±â€…5.37. The mean beginning Surgical Pleth Index value recoded from all of the patients was 23.4 ±â€…8.84 compared with the beginning value; the values recorded during periost dissection, lateral osteotomy, and lower turbinate lateralization were statistically significantly higher (P < 0.005). CONCLUSIONS: Although sufficient depth of anesthesia and standard protocol of analgesia were applied, pain response was found to be significantly higher at some procedures during septorhinoplasty. The authors think that increasing the depth of anesthesia during these procedures will increase the comfort of this operation by inhibiting pain response.

A randomised-controlled, prospective study on the effect of dorsal penile nerve block after TURP on catheter-related bladder discomfort and pain.

PURPOSE: In the present study, the impact of penile nerve block (PNB) on postoperative pain and Catheter-Related Bladder Discomfort (CRBD) in the transurethral resection of prostate(TURP) patients were evaluated. METHODS: Participants of the present study were selected from patients who performed TURP under spinal anaesthesia for benign prostatic hyperplasia (BPH) between January 2018 and July 2020. The present study was planned as a single-centre, randomised-controlled prospective study in which the patients were divided into two groups. Group 1 was administered Control (n:40), and Group 2 ultrasonography(USG) guided PNB (n:40). The patients were included in the Groups, respectively. Visual analogue scale (VAS) scores were questioned and recorded in order to evaluate the postoperative pain complaints of the patients after the operation. In addition, in order to evaluate the CRBD, VAS scores were questioned and recorded as 0th, 0-1th hour, 1st-2nd hour, 2nd-4th hour, 4th-8th hour, 8th-12th hour, and 12th-24th hour. In addition, postoperative pain and need for analgesic drug were recorded. Tramadol was given to patients with moderate to severe CRBD. The findings were compared between the Groups. RESULTS: There was no statistical difference demographic and per-operative data between Group 1 and Group 2. The CRBD and pain-related VAS scores were significantly higher in Group 1 between the 0 and 8th hours. There was no difference between VAS scores in the postoperative 8-24th hours. In total 24 hours, Group 2's need for tramadol was significantly less than Group 1. On examining the factors affecting CRBD in the multivariate analysis, age, body mass index(BMI), prostate volume, operation time do not affect CRBD statistically, and only PNB reduces CRBD (P: .029). While less drug-related complications were observed in Group 2, no serious complications related to PNB were observed. CONCLUSION: Penile nerve block is an effective method for the decrease pain and CRBD after urological surgery. It will also reduce the need for analgesics, and provide painless patients in the postoperative period.

The Effects of Sugammadex on Progesterone Levels in Pregnant Rats.

BACKGROUND: Sugammadex has been shown to decrease the efficiency of progesterone-containing oral contraceptive drugs which possess a steroid structure. AIMS: The aim of the present study was to evaluate the effects of sugammadex on progesterone levels in pregnant rats as well as on the physiological course of the pregnancy. STUDY DESIGN: Animal experiment. METHODS: This study was approved by the Selçuk University Ethical Committee for Experimental Animal Research. Pregnant Winster Albino rats (n=26) were divided into three groups and administered with various intravenous injections on the 7(th) day of pregnancy. The control group (Group K, n=6) received 1.5 mL serum physiologic, the sugammadex group (Group S, n=10) received 30 mg/kg sugammadex and the sugammadex + rocuronium group (Group SR, n=10) received 30 mg/kg sugammadex and 3.5 mg/kg rocuronium. Progesterone levels were measured and the offspring were monitored for morphologic status. RESULTS: Mean progesterone levels were 94.16±15.54 ng/mL in Group K, 87.86±12.48 ng/mL in Group S, and 94.53±16.10 ng/mL in Group SR (p>0.05). No stillbirth or miscarriage was observed in the rats. The mean number of offspring was 6.8±1.47 in Group K, 6.5±1.35 in Group S, and 6.4±1.17 in Group SR. The offspring appeared macroscopically normal. CONCLUSION: Sugammadex does not appear to affect the progesterone levels in pregnant rats in the first trimester and the clinical course. Successful completion of pregnancy and the absence of stillbirth or miscarriage will guide future studies about the use of sugammadex, particularly in the first trimester of the pregnancy.

Determination of optimum time for intravenous cannulation after induction with sevoflurane and nitrous oxide in children premedicated with midazolam.

BACKGROUND: It has been shown that early placement of an intravenous line in children administered sevoflurane anesthesia increased the incidence of laryngospasm and movement. However, the optimal time for safe cannulation after the loss of the eyelash reflex during the administration of sevoflurane and nitrous oxide is not known. AIM: The aim of the study was to determine the optimum time for intravenous cannulation after the induction of anesthesia with sevoflurane and nitrous oxide in children premedicated with oral midazolam. METHOD: We performed a prospective, observer-blinded, up-down sequential, allocation study, and children, aged 2-6 years, ASA physical status I, scheduled for an elective procedure undergoing inhalational induction were included in the study. Anesthesia was induced with sevoflurane and nitrous oxide after premedication with oral midazolam. For the first child, 4 min after the loss of the eyelash reflex, the intravenous cannulation was attempted by an experienced anesthesiologist. The time for intravenous cannulation was considered adequate if movement, coughing, or laryngospasm did not occur. The time for cannulation was increased by 15 s if the time was inadequate in the previous patient, and conversely, the time for cannulation was decreased by 15 s if the time was adequate in the previous patient. The probit test was used in the analysis of up-down sequences. RESULTS: A total of 32 children were enrolled sequentially during the study period. The adequate time for effective intravenous cannulation after induction with sevoflurane and nitrous oxide in 50% and 95% of patients were 1.29 min (95% confidence interval, 0.96-1.54 min) and 1.86 min (95% confidence interval 1.58-4.35 min), respectively. CONCLUSION: We recommend waiting 2 min for attempting intravenous placement following the loss of the eyelash reflex in children sedated with midazolam and receiving an inhalation induction with sevoflurane and nitrous oxide.

Ultrasound-guided multiple peripheral nerve blocks in a superobese patient.

The number of obese patients has increased dramatically worldwide. Morbid obesity is associated with an increased incidence of medical comorbidities and restricts the application choices in anesthesiology. We report a successfully performed combined ultrasound-guided blockade of the femoral, tibial, and common peroneal nerve in a superobese patient. We present a case report of a 31-year-old, ASA-PS II, super obese man (190 kg, 180 cm, BMI: 58 kg/m(2)) admitted to the emergency department with a type II segmental tibia shaft fracture and ankle dislocation after a vehicle accident. After two failed spinal anesthesia attempts, we decided to apply a femoral block combined with a sciatic block. Femoral blocks were successfully performed with US guided in-plane technique. Separate blocks of the tibial and common peroneal nerves were planned after the sciatic nerve could not be located due to the thick subcutaneous tissue. We performed a tibial nerve block at 2 cm above the popliteal crease and common peroneal nerve at the level of the fibular head with US guided in-plane technique. The blocks were successful and no block-related complications were noted. Ultrasound guidance allows new approaches for multiple peripheral nerve blocks with low local anesthetic doses in obese patients.

Effectiveness of the C-MAC video laryngoscope in the management of unexpected failed intubations.

BACKGROUND AND OBJECTIVES: The purpose of this study was to review the experiences of an anesthesiology department regarding the use of a C-MAC videolaryngoscope in unexpected failed intubation attempts. METHODS: Data were analyzed from 42 patients whose intubation attempts using Macintosh direct laryngoscopes had failed, and on whom a C-MAC videolaryngoscope was utilized as the primary rescue device. The success rate of C-MAC in intubation was assessed, and laryngeal views from both devices were compared. RESULTS: The Cormack and Lehane score was III in 41 patients, and IV in one patient, with the Macintosh laryngoscope, while Cormack and Lehane score was I in 27 patients, II in 14 and III in one with CMAC. Tracheal intubation with CMAC was successful on the first attempt in 36 patients (86%), and on the second attempt in 6 patients (14%). No complications were observed other than minor damage (blood on blade) in 8 patients (19%). CONCLUSION: These data provide evidence for the clinical effectiveness of C-MAC videolaryngoscope in managing the unexpected failed intubations in routine anesthesia care. The C-MAC videolaryngoscope is efficient and safe as a primary rescue device in unexpected failed intubations.

Comparison of the C-MAC D-Blade, Conventional C-MAC, and Macintosh Laryngoscopes in Simulated Easy and Difficult Airways.

OBJECTIVE: Recently, to further enhance the potential in the management of difficult airways, the highly angulated D-Blade was added to the C-MAC system. The purpose of this study was to investigate the laryngoscopic view and intubation parameters using the new C-MAC D-Blade in comparison to the conventional C-MAC video laryngoscope and Macintosh direct laryngoscope in simulated easy and difficult airways. METHODS: We recruited 26 experienced anaesthesia providers into a randomized trial. Each performed tracheal intubation of a Laerdal SimMan(®) manikin with each laryngoscope in the following laryngoscopy scenarios: (1) normal airway, (2) cervical spine immobilization, and (3) tongue edema. The intubation times, success rates, number of intubation attempts, laryngoscopic views, and severity of dental compression were recorded. RESULTS: In all scenarios, video laryngoscopes provided better laryngeal exposure than the ML and appeared to produce less dental pressure. In the cervical spine immobilization scenario, D-Blade caused less dental pressure and showed better Cormack-Lehane (CL) classes than the other devices (p<0.001). There were no differences between video laryngoscopes in success of tracheal intubation (p>0.05). The CMAC provided the most rapid intubation. The rate of failure was 19% with ML. In the tongue edema scenario, the CMAC provided the most rapid and successful intubation (p<0.001). There were no differences between video laryngoscopes in laryngoscopic views according to CL classification and dental pressure (p>0.05). The rate of failure was 46% with the ML and 7% with the D-Blade. CONCLUSION: The CMAC D-Blade caused less dental pressure than the conventional C-MAC and ML in the cervical immobilization scenario. The conventional CMAC performed better than the D-Blade and ML in the tongue edema scenario. These two video laryngoscopes may complement each other in various difficult airway situations.

Anaesthetic Management with Thromboelastography in a Patient with Glanzmann Thrombasthenia.

Glanzmann thrombastenia (GT) is a rare disease of an autosomal recessive inheritance characterized with fatal bleeding tendency. The anaesthesiologist should be cognizant of the risk involved and be prepared with necessary measures. In this paper, we present a GT case of a 9-year-old male with hypospadias, which was successfully repaired after platelet transfusions according to the thromboelastography tracings.

Management of the Difficult Paediatric Airway with a Simple Fiberoptic-Assisted Laryngoscope: A Report of Two Cases with Pierre Robin and Patau's (Trisomy 13) Syndrome.

Airway management of children with congenital craniofacial anomalies is a challenge for paediatric anaesthesiologists. We do not have any video-assisted airway device in our department for difficult paediatric intubations. We decided to attach a regular fiberoptic (outer diameter; 3.7 mm, Karl Storz, Germany) scope to a conventional Macintosh Laryngoscope (size 1). We describe two cases of Pierre Robin and Patau's (Trisomy 13) syndrome successfully intubated with a fiberoptic-assisted laryngoscope (FOL). A fiberoptic scope and any size of a laryngoscope blade can be easily assembled in the operating room. The FOL may be a useful device in the setting of difficult paediatric intubation.

Differences in tip visibility and nerve block parameters between two echogenic needles during a simulation study with inexperienced anesthesia trainees.

Needle tip visualization during ultrasound-guided regional anesthesia (UGRA) is necessary for safety and efficacy. However, disruption of the image of the needle tip driven toward the target is a general problem, especially for beginners. The purpose of this study was to compare performance parameters between using the Sonoplex and Stimuplex D-Plus echogenic needles in a simulated ultrasound-guided interventional task by inexperienced anaesthesia residents. After a standardized training session, 28 anesthesiology residents performed simulated nerve blocks in a beef phantom with each needle. All ultrasound images were digitally stored for analysis. The absolute time the needle tip was in view, total procedure time, and angle of needle insertion were subsequently measured objectively by two single investigators. The procedures that used the Sonoplex echogenic needle had significantly better tip visibility and shorter total procedure time at insertion angles between 42° and 64° relative to the phantom surface. We have demonstrated that inexperienced users who used the Sonoplex echogenic needle were able to complete the procedure more quickly. Needles with improved visibility would be a very useful addition to UGRA for inexperienced users.

Combined use of ultrasound guided infraclavicular block and lateral femoral cutaneous nerve block in upper extremity reconstruction requiring large skin graft: case report.

Combined nerve blocks of the upper extremity and lower limb in same operation rarely performed due to the risk of systemic toxicity of local anesthetics. Therefore, general anesthesia is generally preferred in this operations. However, use of ultrasound allows reliable deposition of the anesthetic around the nerves, potentially lowering the local anesthetic requirement. In this case report, we present a 44-year-old, ASA physical status I, male patient who was operated for upper extremity reconstruction requiring skin graft from anterolateral thigh region under ultrasound-guided infraclavicular brachial plexus block and lateral femoral cutaneous nerve block. The block was successful and no block-related complications were noted. We think that combining an ultrasound guided infraclavicular brachial plexus block and a lateral femoral cutaneous nerve block is a clinically useful and safe technique and an alternative anesthetic method for procedures requiring skin grafts for the upper extremity.

[The effects of preemptive dexketoprofen use on postoperative pain relief and tramadol consumption]. / Preemptif deksketoprofen kullaniminin postoperatif agri ve tramadol tüketimine etkisi.

OBJECTIVES: In this study, the efficacy of preemptive dexketoprofen usage on postoperative pain relief and tramadol consumption was evaluated. METHODS: Fifty American Society of Anesthesiologists (ASA)-I or ASA-II patients undergoing plastic surgery were randomized into two groups. Group 1 received dexketoprofen 25 mg and Group 2 received placebo tablets 1 hour (h) before surgery. All patients received a standard anesthetic protocol. At the end of the surgery, all patients received intravenous tramadol with Patient Controlled Analgesia (PCA) device. Pain scores was evaluated with visual analog scale during the postoperative 1st, 8th and 24th h. Tramadol consumption, adverse effects and patient satisfaction were recorded. RESULTS: The pain scores and tramadol consumption were significantly lower in Group 1 (p<0.05). Nausea and vomiting were observed more in Group 2 than Group 1, and patient satisfaction was better in Group 1 (p<0.05). CONCLUSION: Preemptive use of dexketoprofen reduced postoperative tramadol consumption and incidence of adverse events.

[The effects of intravenous dexketoprofen on postoperative analgesia and morphine consumption in patients undergoing abdominal hysterectomy]. / Abdominal histerektomi uygulanan olgularda intravenöz deksketoprofenin postoperatif analjezi ve morfin tüketimine etkisi.

OBJECTIVES: Dexketoprofen trometamol is a water-soluble salt of the dextrorotatory enantiomer of the nonsteroidal anti-inflammatory drug ketoprofen. The aim of this study was to investigate the effect of intravenous dexketoprofen on postoperative pain. METHODS: This study was performed on 50 (ASA I-II) patients scheduled for abdominal hysterectomy. Fifty patients were randomized into two equal groups. Patients received saline solution (Group I) or 50 mg intravenous dexketoprofen (Group II) 1 hour (h) before surgery and 8-16 h after surgery. All patients received a standard anesthetic protocol. At the end of surgery, all patients received intravenous (IV) morphine via a PCA (patient- controlled analgesia) device. Pain scores were assessed at 2, 6, 12 and 24 h after surgery. Morphine consumption and adverse effects were noted during the first 24 h after the surgery. The pain scores were significantly lower in the dexketoprofen group compared with the control group (p<0.05). RESULTS: The cumulative morphine consumption was also lower in the dexketoprofen group than the control group (p<0.05). No significant difference was observed in adverse effects between the groups (p>0.05). CONCLUSION: We conclude that the administration of IV dexketoprofen provided a significant analgesic benefit and decreased the morphine requirements in patients undergoing abdominal hysterectomy.
