Effectiveness of simplified predictive intubation difficulty score and thyromental height in head and neck surgeries: an observational study / Eficácia do escore simplificado preditivo de dificuldade de intubação e da altura tiromentoniana em cirurgias de cabeça e pescoço: estudo observacional

Abstract Background and objectives: In this study, we aimed to investigate the predictive value of different airway assessment tools, including parts of the Simplified Predictive Intubation Difficulty Score (SPIDS), the SPIDS itself and the Thyromental Height Test (TMHT), in intubations defined as difficult by the Intubation Difficulty Score (IDS) in a group of patients who have head and neck pathologies. Methods: One hundred fifty-three patients who underwent head and neck surgeries were included in the study. The Modified Mallampati Test (MMT) result, Thyromental Distance (TMD), Ratio of the Height/Thyromental Distance (RHTMD), TMHT, maximum range of head and neck motion and mouth opening were measured. The SPIDSs were calculated, and the IDSs were determined. Results: A total of 25.4% of the patients had difficult intubations. SPIDS scores >10 had 86.27% sensitivity, 71.57% specificity and 91.2% Negative Predictive Value (NPV). The results of the Receiver Operating Curve (ROC) analysis for the airway screening tests and SPIDS revealed that the SPIDS had the highest area under the curve; however, it was statistically similar to other tests, except for the MMT. Conclusions: The current study demonstrates the practical use of the SPIDS in predicting intubation difficulty in patients with head and neck pathologies. The performance of the SPIDS in predicting airway difficulty was found to be as efficient as those of the other tests evaluated in this study. The SPIDS may be considered a comprehensive, detailed tool for predicting airway difficulty.

Resumo Justificativa e objetivos: Neste estudo, avaliamos o valor preditivo de diferentes ferramentas de avaliação das vias aéreas, incluindo componentes do Escore Simplificado Preditivo de Intubação Difícil (ESPID), o próprio ESPID e a Medida da Altura Tireomentoniana (MATM), em intubações definidas como difícies pelo Escore de Dificuldade de Intubação (EDI) em um grupo de pacientes com patologia de cabeça e pescoço. Método: Incluímos no estudo 153 pacientes submetidos a cirurgia de cabeça e pescoço. Coletamos os resultados do Teste de Mallampati Modificado (TMM), Distância Tireomentoniana (DTM), Razão Altura/Distância Tireomentoniana (RADTM), MATM, amplitude máxima de movimentação da cabeça e pescoço e da abertura da boca. Os ESPIDs foram calculados e os EDIs, determinados. Resultados: Observamos intubação difícil em 25,4% dos pacientes. Os escores de ESPID > 10 tiveram sensibilidade de 86,27%, especificidade de 71,57% e valor preditivo negativo de 91,2% (VPN). O resultado da análise da curva de operação do receptor (curva ROC) para os testes de avaliação das vias aéreas e ESPID mostrou que o ESPID tinha a maior área sob a curva; no entanto, foi estatisticamente semelhante a outros testes, exceto para o TMM. Conclusões: O presente estudo demonstra o uso prático do ESPID na previsão da dificuldade de intubação em pacientes com patologia de cabeça e pescoço. O desempenho do ESPID na predição de via aérea difícil mostrou-se tão eficiente quanto os demais testes avaliados neste estudo. O ESPID pode ser considerado ferramenta abrangente e detalhada para prever via aérea difícil.

Is a Combination of the Serratus Intercostal Plane Block and Rectus Sheath Block Superior to the Bilateral Oblique Subcostal Transversus Abdominis Plane Block in Laparoscopic Cholecystectomy?

OBJECTIVE: The serratus intercostal plane block (SIPB) is a recently defined interfascial plane block. The oblique subcostal transversus abdominis plane block (OSTAP) is another type of interfascial plane block, and it is also used as a part of multimodal analgesia in patients undergoing laparoscopic cholecystectomy (LC). In this retrospective study, we evaluated the effects of the bilateral OSTAP and a combination of the right SIPB and bilateral rectus sheath block (RSB) on the postoperative pain and analgesia requirement in patients undergoing LC. MATERIALS AND METHODS: Data of the patients who underwent LC between May 2018 and November 2018 were evaluated retrospectively. Postoperative pain was evaluated using the numeric rating scale (NRS), and 24-hour tramadol consumption and rescue analgesia requirements were compared. RESULTS: Bilateral OSTAP was applied to 47 patients, and SIPB+RSB was applied to 25 patients. Postoperative pain scores were similar between the two groups. In the first 24 hours, tramadol requirement in the SIPB+RSB group was significantly lower than in the OSTAP block group (p<0.001). There was no statistically significant difference between the NRS averages at different time frames between the two block groups. CONCLUSION: We found that when SIPB is used as a part of multimodal analgesia in a combination with RSB in LS, it improves the quality of analgesia and decreases the analgesic requirement compared to patients undergoing a bilateral OSTAP block. Randomized controlled trials are necessary to compare the effects of SIPB alone and in a combination with other blocks in LC.

Evaluation of ultrasound-guided transversalis fascia plane block for postoperative analgesia in cesarean section: A prospective, randomized, controlled clinical trial.

STUDY OBJECTIVE: Cesarean Delivery (CD) is a commonly performed obstetric procedure. Adding a regional anesthesia technique to multimodal analgesia in CD, may improve the quality of postoperative analgesia. In this study we evaluated the efficacy of Transversalis Fascia Plane Block (TFPB) for postoperative analgesia management in CD. DESIGN: Blinded, prospective, randomized study. SETTING: Postoperative recovery room & ward, tertiary university hospital, Istanbul, Turkey, PATIENTS: Seventy-five patients (ASA II-III) scheduled to undergo Cesarean delivery were recruited. Following exclusion, 70 patients were randomized into two equal groups (block and control group). INTERVENTIONS: Standard multimodal analgesia (routine paracetamol and tramadol PCA in addition to diclophenac sodium as rescue analgesia) was performed in Group C while TFPB block was also performed in the intervention (TFPB) group. MEASUREMENTS: The primary outcome was tramadol consumption within the first 24 h. The secondary outcome was Numeric Rating Scale (NRS) scores during rest and movement/coughing. MAIN RESULTS: Tramadol consumption in the first 24 h was 175 ±â€¯72.32 mg in the control and 101.42 ±â€¯51.45 mg in the TFPB group (p < 0.05). NRS was lower in Group TFPB during the first 3 h and at the 12th hour. There was no difference in NRS scores at other hours. CONCLUSION: Bilateral ultrasound guided TFPB leads to effective analgesia and a decrease in analgesia requirement in first 24 h in patients undergoing CD.

Evaluation of Ultrasound-Guided Erector Spinae Plane Block and Oblique Subcostal Transversus Abdominis Plane Block in Laparoscopic Cholecystectomy: Randomized, Controlled, Prospective Study.

BACKGROUND: Oblique subcostal transversus abdominis plane block (OSTAP) is a recently described regional anesthetic technique used in upper abdominal surgeries such as laparoscopic cholecystectomy (LC). Erector spinae plane block (ESPB) has also been reported for postoperative analgesia in LC. AIM: We aimed to compare the effectiveness of OSTAP and ESPB in providing postoperative analgesia in patients undergoing these surgeries. SETTING AND DESIGN: This study was designed as a double-blinded, prospective, randomized, efficiency study in a tertiary university hospital, postoperative recovery room, and ward. MATERIALS AND METHODS: A total of 72 patients were recruited and 60 patients were randomized into three equal groups (ESPB, OSTAP, and control group). Pain intensity between groups was compared using Numeric Rating Scale (NRS) scores. In addition, consumption of paracetamol and tramadol and additional rescue analgesic requirement were measured. Standard multimodal analgesia was performed in all groups, while ESPB block was also performed in Group ESPB and OSTAP block was also performed in group OSTAP. STATISTICAL ANALYSIS USED: Descriptive statistics were expressed as mean ± standard deviation. Independent t-test, Mann-Whitney U-test, Chi-square test, Fisher's exact test, Shapiro-Wilk test, one-way ANOVA, and post hoc Tukey's analysis were used for statistical analysis. RESULTS: NRS was lower in block groups during the first 3 h. There was no difference in NRS scores at other hours. Analgesic consumption and rescue analgesic requirement were lower in groups ESPB and OSTAP when compared to those of control group. Block groups were similar. CONCLUSION: Bilateral ultrasound-guided ESPB and OSTAP performed at the end of LC lead to akin analgesia requirement and improve the quality of multimodal analgesia.

Can Low-dose Tranexamic Acid Decrease Blood Loss and Transfusion Requirements in Total Knee Arthroplasty?

Introduction Tranexamic acid (TA) has been used successfully in primary total knee arthroplasty (TKA) to minimize blood loss and transfusions. The aim of this study was to evaluate the effect of perioperative single low-dose TA administration on postoperative blood loss and necessity for blood transfusion in patients undergoing total knee arthroplasty under spinal anesthesia. Material and Methods Data of patients undergoing TKA between January 2013 through December 2015 were retrospectively reviewed. Patients that underwent unilateral knee arthroplasty under spinal anesthesia were separated into two groups: those where TA was used (10 mg/kg) and a control group where TA was not used. The following data were collected from medical records and compared between groups according to demographics, hemoglobin levels, and drainage amount. Results A total of 48 patients' data were evaluated (TA: 20; control: 28). The use of tranexamic acid in total knee arthroplasties seemed to reduce the postoperative drainage rate and blood transfusion requirement. Average 24-hour drainage levels were significantly lower in the TA group when compared to the control group. Required 24-hour total blood transfusion amounts were significantly higher in the control group. There was no difference in preoperative and postoperative sixth or 24th-hour hemoglobin levels between the groups. Conclusion A low or single dose of TA is a safe and effective agent that significantly lowers blood loss and allogeneic blood transfusion requirements.

Evaluation of ultrasound-guided erector spinae plane block for postoperative analgesia in laparoscopic cholecystectomy: A prospective, randomized, controlled clinical trial.

STUDY OBJECTIVE: Laparoscopic cholecystectomy (LC) is a commonly performed minimally invasive procedure that has led to a decrease in procedure-related mortality and morbidity. However, LC requires analgesia that blocks both visceral and somatic nerve fibers. In this study, we evaluated the effectiveness of Erector Spinae Plane Block (ESPB) for postoperative analgesia management in LC. DESIGN: Single-blinded, prospective, randomized, efficiency study. SETTING: Tertiary university hospital, postoperative recovery room & ward. PATIENTS: 36 patients (ASA I-II) were recruited in two equal groups (block and control group). Following exclusion, 30 patients were included in final analysis. INTERVENTIONS: Standard multimodal analgesia was performed in Group C (control) while ESPB block was also performed in Group B (block). MEASUREMENTS: Pain intensity between groups were compared using Numeric Rating Scores (NRS). Also, tramadol consumption and additional rescue analgesic requirement were measured. MAIN RESULTS: NRS was lower in Group B during the first 3 h. There was no difference in NRS scores at other hours. Tramadol consumption was lower in Group B during the first 12 h. Less rescue analgesia was required in Group. CONCLUSION: Bilateral ultrasound guided ESPB leads to effective analgesia and a decrease in analgesia requirement in first 12 h in patients undergoing LC.

Comparison of Ultrasound-Guided Lumbar Erector Spinae Plane Block and Transmuscular Quadratus Lumborum Block for Postoperative Analgesia in Hip and Proximal Femur Surgery: A Prospective Randomized Feasibility Study.

STUDY OBJECTIVE: Lumbar Erector spinae Plane block (L-ESPB) is a modification of a recently described block. Both L-ESPB and Transmuscular Quadratus Lumborum block (QLB-T) have been reported to provide effective postoperative analgesia in hip and proximal femur surgery. Herein, we compare the effectiveness of L-ESPB and QLB-T in providing postoperative analgesia in patients undergoing hip and femur operations. DESIGN: Double-blinded, prospective, randomized, feasibility study. SETTING: Tertiary university hospital, postoperative recovery room and ward. METHODOLOGY: A total of 72 patients (American Society of Anesthesiology physical status classification II-III) were recruited. After exclusion, 60 patients were allocated to three equal groups (control, L-ESB and QLB-t). INTERVENTIONS: Standard multimodal analgesia was performed in the control group while L-ESPB or QLB-T was performed in the block groups. MEASUREMENTS: Pain intensity between groups was compared using Numeric Rating Scores. Furthermore, tramadol consumption and additional rescue analgesic requirement was measured. RESULTS: There was no difference between demographic data or type of surgery. While there was no difference in Numeric Rating Scale (NRS) score at any hour between the block groups; NRS scores at the 1st, 3rd and 6th h, tramadol consumption during the first 12 h and total tramadol consumption, the number of patient required rescue analgesic in 24 h were significantly higher in the control group compared to both block groups. CONCLUSION: While L-ESPB and QLB-T have similar effect, they improve analgesia quality in patients undergoing hip and proximal femoral surgery when compared to standard intravenous analgesia regimen.

Evaluation of analgesic regimens in total knee arthroplasty, retrospective study.

OBJECTIVE: Analgesic therapies have an immense role in early rehabilitation period after total knee arthroplasty (TKA) and multimodal approaches should be considered as the first choice of treatment. In this retrospective study, the aim was to evaluate the effectiveness of multimodal analgesic therapies for TKA, including femoral nerve block (FNB) and patient controlled analgesia (PCA). METHODS: The data of 79 patients who underwent TKA between January and December 2016 were retrospectively evaluated. In all, 63 patients met the inclusion criteria. Hemodynamic records and Visual Analogue Scale (VAS) pain scores for postoperative 0, 2, 4, 6, 9, and 12 hours were evaluated and patients were separated into 3 groups. Group 1: FNB with 0.25% bupivacaine, Group 2: FNB with 0.166% bupivacaine, and Group 3: No FNB. RESULTS: The average age of the patients was 64.3±14.9 years and average body mass index (BMI) was 32.5±5.3 kg/m2. There was no statistical difference between groups in age, gender, American Society of Anesthesiologists (ASA) classification of physical health scores, BMI, or anesthesia type (p<0.05). When VAS scores at postoperative time intervals were compared, there was a statistically significant difference between Group 1 and Group 2 (p>0.05). When difference between Groups 1 and 3 and Groups 2 and 3 were compared, the difference was statistically significant for VAS 0 (p>0.05). Additional analgesic use was highest in Group 3. CONCLUSION: This study demonstrated that FNB significantly decreases postoperative pain intensity and additional analgesia requirement in patients undergoing TKA. A concentration of 0.166% bupivacaine is as effective as a concentration of 0.25% when used as part of a multimodal analgesia regimen in TKA.

YouTube as an information source of spinal anesthesia, epidural anesthesia and combined spinal and epidural anesthesia / YouTube como fonte de informação de raquianestesia, anestesia peridural e anestesia combinada raquiperidural

Abstract Introduction Social media as YouTube have become a part of daily life and many studies evaluated health-related YouTube videos. Our aim was to evaluate videos available on YouTube for the conformity to textbook information and their sufficiency as a source for patient information. Material and method A search of the YouTube website was performed using the keywords "spinal anesthesia, epidural anesthesia, combined spinal epidural anesthesia". Firstly, 180 videos were evaluated and the characteristics of the video were noted, and the features of the video too were noted if the video was regarding neuraxial anesthesia. Questionnaire 1 (Q1) evaluating the video quality relating to neuraxial anesthesia was designed using a textbook as reference and questionnaire 2 (Q2) was designed for evaluating patient information. Results After exclusions, 40 videos were included in the study. There was no difference in Q1 or Q2 scores when videos were grouped into 4 quarters according to their appearance order, time since upload or views to length rate (p > 0.05). There was no statistical difference between Q1 or Q2 scores for spinal, epidural or combined videos (p > 0.05). Videos prepared by a healthcare institute have a higher score in both Questionnaires 1 and 2 (10.87 ± 4.28 vs. 5.84 ± 2.90, p = 0.044 and 3.89 ± 5.43 vs. 1.19 ± 3.35, p = 0.01 respectively). Conclusion Videos prepared by institutes, societies, etc. were of higher educational value, but were still very lacking. Videos should be prepared in adherence to available and up-to-date guidelines taking into consideration appropriate step by step explanation of each procedure, patient safety and frequently asked questions.

Resumo Introdução As mídias sociais como o YouTube tornaram-se uma parte do cotidiano e muitos estudos avaliaram vídeos do YouTube relacionados à saúde. Nosso objetivo foi avaliar os vídeos disponíveis no YouTube para identificar a existência de conformidade com as informações em livros didáticos e sua suficiência como fonte de informação para o paciente. Material e método Uma pesquisa no site YouTube foi feita com as palavras-chave spinal anesthesia, epidural anesthesia, combined spinal-epidural anesthesia (raquianestesia, anestesia peridural, anestesia combinada raquiperidural). Em primeiro lugar, avaliamos 180 vídeos e observamos suas características e se eram referentes à anestesia neuraxial. O questionário de avaliação da qualidade do vídeo (Q1) relativa à anestesia neuraxial foi criado com um livro didático como referência e o questionário 2 (Q2) foi criado para avaliar as informações ao paciente. Resultados Após exclusões, 40 vídeos foram incluídos no estudo.
