Assessment of mucociliary clearance as an indicator of nasal function in patients with COVID-19: a cross-sectional study.

PURPOSE: We assessed the effects of COVID-19 infection on nasal mucociliary activity. METHODS: The study was conducted in the pandemic wards of Adiyaman University Training and Research Hospital during April and May 2020. All patients admitted to the COVID-19 pandemic wards during the study period were invited to participate in the study. The study included 40 adults who agreed to participate and underwent a mucociliary clearance test successfully. The primary outcome was mucociliary clearance time and the secondary variables of interest were age, sex, and sino-nasal outcome test-22 scores. The control group included 40 concomitant healthy patients who visited the outpatient ear, nose and throat clinic with non-nasal symptoms. RESULTS: The study included 40 COVID-19-positive patients and 40 healthy controls. The mean mucociliary clearance times of the study (15.53 ± 5.57 min) and control (9.50 ± 3.70 min) groups were significantly different (Z = 4.675, p < 0.001). However, the mucociliary clearance time was not significantly different between males and females (t = 0.590, p = 0.558). CONCLUSIONS: Nasal mucociliary clearance time was prolonged in COVID-19 patients compared to healthy controls. Thus, we conclude that smell and taste are crucial symptoms that should not be overlooked in patients suspected of COVID-19 disease.

Validity and reliability of Turkish version of family satisfaction in the intensive care unit.

To evaluate the quality of care that is provided in intensive care units, needs and satisfaction of the patient relatives must also be considered. The aim of the study is to test the Turkish version of the Family Satisfaction in the Intensive Care Unit (FS-ICU-24) Survey, which was developed by Heyland et al. This study was planned and applied as a methodological study. Survey was conducted in the intensive care units of a military education and research hospital and a medical faculty hospital, department of anaesthesia and reanimation in the capital city Ankara of Turkey. Sample of the survey was composed of 120 participants. Cronbach's alpha value for the FS-ICU-24 general internal consistency in this study was calculated as 0.95 for total scale. In this study, the Turkish version of the FS-ICU-24 was found to be reliable and valid with Turkish population.

Results of cochlear implant surgery in patients with auditory neuropathy.

OBJECTIVES: The primary aim of this study was to analyze the benefit of cochlear implants for patients with auditory neuropathy. The secondary aim was to identify risk factors for auditory neuropathy. MATERIALS AND METHODS: Patients with cochlear implants (CIs) who were educated in hearing rehabilitation schools were included in the study. A total of 175 children were operated on for cochlear implantation between August 2019 and August 2021 in the department of otorhinolaryngology at different centers in Turkey, and while 16 (9.1%) of those patients had auditory neuropathy spectrum disorder (ANSD), 159 (90.9%) had sensorineural hearing loss (SNHL). Differences in auditory perception between the two groups were examined. Auditory perception tests were applied for these patients 6 months after CI surgery. The auditory perception performances of the patients were evaluated with the Evaluation of Auditory Responses to Speech (EARS) battery, including the Littlears, Lip, Bis4, Bis12, Cap, Sir, Mtp-3, Mtp-6, Mtp-12, Matrix A1, and Gasp tests. RESULTS: All patients had profound bilateral SNHL. Four auditory perception tests (Littlears, Bis-12, Sir, Matrix A1) showed similar results between patients with ANSD and SNHL, but seven auditory perception tests (Lip, Bis-4, Cap, Mtp-3, Mtp-6, Mtp-12, Gasp) showed significantly higher results among patients with SNHL. Hyperbilirubinemia, prematurity, consanguineous marriage, and family history of hearing loss were found to be common among patients with ANSD. CONCLUSIONS: ANSD patients who do not benefit from hearing aids benefit from CI surgery.

Computed Tomography and Magnetic Resonance Imaging for Congenital Hearing Loss: A Retrospective Study.

OBJECTIVE: The aim of this study is to evaluate the relationship between the cochlear nerve and the anatomical structures of the cochlea and internal acoustic canal in patients with congenital hearing loss. MATERIALS AND METHODS: Temporal tomography and magnetic resonance images of 44 patients (88 ears) with non-syndromic congenital hearing loss were retrospectively analyzed between 2018 and 2021. Patients were divided into 2 groups according to cochlear nerve hypoplasia. Cochlear nerve canal width, cochlear basal/ middle turn widths, and internal auditory canal widths were examined. RESULTS: Cochlear nerve hypoplasia was detected in 18.2% (n=16) of the patients and all of the patients with cochlear nerve hypoplasia had severe hearing loss. A statistically significant difference was found between the structures' widths in patients with and without cochlear nerve hypoplasia, in cochlear nerve canal and coronal width of the internal auditory canal. When stenosis is accepted as <1.4 mm for cochlear nerve canal and <3.80 mm for coronal width of the internal auditory canal, cochlear nerve hypoplasia differs statistically between the groups in measurements (respectively; P < .001, P=.018). CONCLUSIONS: In patients with sensorineural hearing loss, cochlear nerve hypoplasia may accompany. Anatomical structures are important in predicting cochlear nerve hypoplasia from temporal computed tomography. Cochlear nerve hypoplasia should be suspected if the cochlear nerve canal and coronal width of the internal auditory canal are less than 1.4 mm and 3.8 mm, respectively, on temporal computed tomography.

Effect of headphones on sevoflurane requirement for MRI.

BACKGROUND: Acoustic noise may have adverse effects, even in patients under general anesthetic. OBJECTIVE: We aimed to determine the effect of headphones on sevoflurane requirements in children undergoing general anesthesia for an MRI scan. MATERIALS AND METHODS: Children scheduled for MRI were enrolled in the study. Sevoflurane was used for general anesthesia in all children. Patients were randomly divided into two groups, one to wear headphones and the other none. After reaching a predetermined end-tidal concentration, the MRI scan was initiated, and the patient was evaluated by an observer blinded to the concentration of sevoflurane. Awakening was defined as eye opening, onset of continued purposeful movement or phonation. Using the Dixon up-and-down method, each target concentration was determined by the response of the previous child in the same group. RESULTS: The study included 28 children undergoing MRI. There was a significant difference in ED50 between the two groups (0.92, 0.81-1.02, vs. 0.47, 0.42-0.63; P < 0.001). The times to spontaneous arm and leg movements, eye opening and discharge from the post-anesthesia care unit were significantly shorter in patients with headphones than in those without (P < 0.001). However, there was no difference in times to hospital discharge (P = 0.056). CONCLUSION: Noise-concealing headphones decrease inhalational anesthetic requirements and facilitate recovery. We recommend the routine use of headphones in children undergoing an MRI scan.

Evaluation of the associations between maxillary sinus dimensions and adenoid hypertrophy using multislice computed tomography.

INTRODUCTION: Adenoid hypertrophy is especially common in childhood, raising the concern that such growth might affect maxillary sinus volumes during the developmental period. This study evaluated the developmental relationships between maxillary sinus volumes and adenoid hypertrophy via computed tomography. MATERIALS AND METHODS: It was examined computed tomographic images of 118 individuals: 61 boys and 57 girls. The participants were divided into a healthy control group (n = 59) and an experimental group (with adenoid hypertrophy) (n = 59). Raw data were recorded in DICOM format and analysed using the ITK-SNA algorithm; it was measured the right, left, and total maxillary sinus volumes and adenoid tissue sizes. RESULTS: It was found significant between-group differences in the three maxillary sinus volumes and adenoid tissue dimensions (linear maximum anterior and posterior depth; maximum upper and lower height, and maximum width to the right and left) (all p<0.001). On the contrary, there was no significant difference according to sex in terms of either maxillary sinus volumes or linear adenoid tissue measurements. Maxillary sinus volumes increased significantly according to age in both groups. CONCLUSION: Adenoid hypertrophy decreases the maxillary sinus volumes, regardless of sex. The impacts of adenoid growth on maxillary sinus aeration and sinus disease should be further investigated.

Evaluation of myocardial performance index in patients with COVID-19: An echocardiographic follow-up study.

Introduction and Objectives: Myocardial performance may be impaired in cytokine-mediated immune reactions. The myocardial performance index (MPI) is a practical parameter that reflects systolic and diastolic cardiac function. We aimed to assess the MPI in patients with COVID-19. Methods: The study population consisted of 40 healthy controls and 40 patients diagnosed with COVID-19 who had mild pneumonia and did not need intensive care treatment. All participants underwent echocardiographic examination. First, the MPI and laboratory parameters were compared between healthy controls and patients in the acute period of infection. Second, the MPI and laboratory parameters were compared between the acute infection period and after clinical recovery. Results: Compared with healthy controls, patients with COVID-19 had a significantly higher MPI (0.56±0.09 vs. 0.41±0.06, p<0.001), longer isovolumic relaxation time (IRT) (112.3±13.4 vs. 90.6±11.2 ms, p<0.001), longer deceleration time (DT) (182.1±30.6 vs. 160.8±42.7 ms, p=0.003), shorter ejection time (ET) (279.6±20.3 vs. 299.6±34.7 ms, p<0.001) and higher E/A ratio (1.53±0.7 vs. 1.21±0.3, p<0.001). Statistically significantly higher MPI (0.56±0.09 vs. 0.44±0.07, p<0.001), longer IRT (112.3±13.4 vs. 91.8±12.1 ms, p<0.001), longer DT (182.1±30.6 vs. 161.5±43.5 ms, p=0.003), shorter ET 279.6±20.3 vs. 298.8±36.8 ms, p<0.001) and higher E/A ratio (1.53±0.7 vs. 1.22±0.4, p<0.001) were observed during the acute infection period than after clinical recovery. Left ventricular ejection fraction was similar in the controls, during the acute infection period and after clinical recovery. Conclusions: Subclinical diastolic impairment without systolic involvement may be observed in patients with COVID-19. This impairment may be reversible on clinical recovery.

Introducão e objetivos: O desempenho miocárdico pode ser prejudicado em reações imunes mediadas por citocinas. O índice de performance miocárdico (IPM) é um parâmetro que reflete a função cardíaca sistólica e diastólica. O nosso objetivo foi avaliar o IPM em doentes com COVID-19. Métodos: O presente estudo consistiu em analisar 40 casos controlo saudáveis e 40 doentes com diagnóstico de COVID-19 que apresentavam pneumonia ligeira e não necessitavam de tratamento intensivo. Todos os participantes foram submetidos a avaliação ecocardiográfica. Primeiro, o IPM e os parâmetros laboratoriais foram comparados entre os casos controlo saudáveis e os doentes com período agudo de infeção. Em segundo lugar, o IPM e os parâmetros laboratoriais foram comparados entre o período agudo de infeção e após a recuperação clínica. Resultados: Em comparação com os casos controlo saudáveis, os doentes com COVID-19 tiveram um IPM significativamente maior (0,56±0,09 versus 0,41±0,06, p<0,001), tempo de relaxamento isovolumétrico (TRI) mais longo (112,3±13,4 versus 90,6±11, 2 ms, p<0,001), tempo de desaceleração maior (TD) (182,1±30,6 versus 160,8±42, 7 ms, p=0,003), tempo de ejeção (TE) menor (279,6±20,3 versus 299,6±34, 7 ms, p<0,001) e razão E/A maior (1,53±0,7 versus 1,21±0,3, p<0,001). Um IPM superior estatisticamente significativo (0,56±0,09 versus 0,44±0,07, p<0,001), um TRI mais longo (112,3±13,4 versus 91,8±12, 1 ms, p<0,001), um TD mais longo (182,1±30,6 versus 161,5±43,5 ms, p=0,003), um TE mais curto (279,6±20,3 versus 298,8±36,8 ms, p<0,001) e razão E/A mais elevada (1,53±0,7 versus 1,22±0,4, p<0,001) foram observados durante o período agudo de infeção em comparação com aqueles após a recuperação clínica. A fração de ejeção do ventrículo esquerdo foi semelhante nos casos controlo saudáveis, período agudo de infeção e após a recuperação clínica. Conclusão: A disfunçao diastólica subclínica sem difunção sistólica pode ser observada em doentes com COVID-19. Esta deficiência pode ser reversível na recuperação clínica.

Effect of septoplasty on left ventricular myocardial performance in patients with nasal septum deviation.

INTRODUCTION: Nasal septum deviation is the leading cause of upper airway obstruction. Chronic upper airway obstruction may cause myocardial injury due to chronic hypoxia. Effects of septoplasty on left venticular diastolic and sistolic functions are not well known. The myocardial performance index is an easy-to-apply and reliable parameter that reflects systolic and diastolic cardiac functions. OBJECTIVE: The present study aimed to investigate the effect of nasal septoplasty on the myocardial performance index in patients with nasal septal deviation. METHODS: This prospective study consisted of 50 consecutive patients who underwent septoplasty due to symptomatic prominent C- or S-shaped nasal septal deviation. Transthoracic echocardiogarphy was performed in all patients before and 3 months after septoplasty. Calculated myocardial performance indices were compared. RESULTS: Significantly higher left ventricular myocardial performance index (0.52 ±â€¯0.06 vs. 0.41 ±â€¯0.04, p <  0.001), longer isovolumic relaxation time (95.0 ± 12.5 vs. 78.0 ± 8.6 ms, p <  0.001), longer isovolumic contraction time (45.5 ± 7.8 vs. 39.5 ± 8.6 ms, p <  0.001), longer deceleration time (184.3 ± 32.5 vs. 163.6 ± 45.4 ms, p =  0.004), higher ratio of transmitral early to late peak velocities (E/A) (1.42 ± 0.4 vs. 1.16 ± 0.2, p =  0.006) and shorter ejection time (270.1 ± 18.3 vs. 286.5 ± 25.8 ms, p <  0.001) were observed before septoplasty when compared to values obtained 3 months after septoplasty. Left ventricular systolic ejection fraction was similar before and after septoplasty (63.8±2.8% vs. 64.6±3.2%, p  = 0.224). CONCLUSION: Septoplasty surgery not only reduces nasal blockage symptoms in nasal septal deviation patients but also may improve left ventricular performance. Thus, treatment of nasal septal deviation without delay is suggested to prevent possible future cardiovascular events.

Spinal 5-HT7 receptors play an important role in the antinociceptive and antihyperalgesic effects of tramadol and its metabolite, O-Desmethyltramadol, via activation of descending serotonergic pathways.

BACKGROUND: Tramadol is an analgesic drug, and its mechanism of action is believed to be mediated by the mu-opioid receptor. A further action of tramadol has been identified as blocking the reuptake of serotonin (5-HT). One of the most recently identified subtypes of 5-HT receptor is the 5-HT7 receptor. Thus, the authors aimed to examine the potential role of serotonergic descending bulbospinal pathways and spinal 5-HT7 receptors compared with that of the 5-HT2A and 5-HT3 receptors in the antinociceptive and antihyperalgesic effects of tramadol and its major active metabolite O-desmethyltramadol (M1) on phasic and postoperative pain models. METHODS: Nociception was assessed by the radiant heat tail-flick and plantar incision test in male Balb-C mice (25-30 g). The serotonergic pathways were lesioned with an intrathecal injection of 5,7-dihydroxytryptamine. The selective 5-HT7, 5-HT2, and 5-HT3 antagonists; SB-269970 and SB-258719; ketanserin and ondansetron were given intrathecally. RESULTS: Systemically administered tramadol and M1 produced antinociceptive and antihyperalgesic effects. The antinociceptive effects of both tramadol and M1 were significantly diminished in 5-HT-lesioned mice. Intrathecal injection of SB-269970 (10 microg) and SB-258719 (20 microg) blocked both tramadol- and M1-induced antinociceptive and antihyperalgesic effects. Ketanserin (20 mumicrog) and ondansetron (20 microg) were unable to reverse the antinociceptive and antihyperalgesic effects of tramadol and M1. CONCLUSIONS: These findings suggest that the descending serotonergic pathways and spinal 5-HT7 receptors play a crucial role in the antinociceptive and antihyperalgesic effects of tramadol and M1.

[A clinic's experiences in postoperative patient controlled analgesia]. / Postoperatif hasta kontrollü analjezide bir klinigin deneyimleri.

OBJECTIVES: Postoperative analgesia technique varies depending on the operation, patient, anesthetist, and circumstances. PCA (patient controlled analgesia) is an effective way of supporting postoperative analgesia. In this study, we aimed to present the efficacy and safety of our postoperative PCA treatment and the patient profile along with the requirements, preferences and decision-making process. METHODS: We discuss herein the PCA protocols of our clinic, the overall distribution of operations for which PCA was applied and the principles by which a pain team works. RESULTS: The operations for which PCA was applied included knee prosthesis, cesarean section, hip prosthesis, lower extremity trauma surgery, painless delivery, gastrointestinal surgery, multiple trauma surgery, thoracotomy, hysterectomy, laminectomy, and urogenital surgery. Postoperative PCA alone was successful in 89% of the patients, and with the supplemental analgesic agent, it was successful in an additional 6% of the patients, thus achieving a total success rate of 95%. CONCLUSION: We believe the epidural and intravenous PCA protocols applied in our clinic for postoperative analgesia are effective and safe.

Ameliorative effects of proanthocyanidin on renal ischemia/reperfusion injury.

INTRODUCTION: Several natural products have been reported to have beneficial effects on ischemia/reperfusion (I/R) injury, particularly from a preventative perspective. Therefore, this study was designed to investigate the efficiency of proanthocyanidin (PA), a natural product derived from grape seed, on renal dysfunction and injury induced by I/R of rat kidney. MATERIALS AND METHODS: Twenty-four male Sprague-Dawley rats were divided into three groups: sham-operated, I/R, I/R+PA. Rats were given PA (100 mg/kg/day peroral) 7 days prior to I/R. All rats except sham-operated underwent 60 min of bilateral renal ischemia followed by 6 h of reperfusion. After reperfusion, kidneys and blood were obtained for evaluation. Superoxide dismutase, glutathione peroxidase, malondialdehyde, protein carbonyl content, and nitrite/nitrate level (NO(x)) were determined in the renal tissue. Serum creatinine (S(Cr)), blood urea nitrogen (BUN), and aspartate aminotransferase (AST) were determined in the blood. Additionally, renal sections were used for histological grade of renal injury. RESULTS: PA significantly reduced the I/R-induced increases in S(Cr), BUN, and AST. In addition, PA markedly reduced elevated oxidative stress product, restored decreased antioxidant enzymes, and attenuated histological alterations. Moreover, PA attenuated the tissue NO(x), levels indicating reduced NO production. CONCLUSIONS: The pretreatment of rats with PA reduced the renal dysfunction and morphological changes, ameliorated cellular injury, and restored renal antioxidant enzymes caused by renal I/R.

A typical low-back pain caused by an atypical etiology.

OBJECTIVE: Pain arising in the lumbar spine can have many etiologies, nearly 80% of which cannot be established with certainty. We present a very rare cause of back pain. CASE REPORT: A 54-year-old woman presented with a 2-month history of low-back pain and right-sided sciatica. Conventional analgesics, physiotherapy, and epidural steroid application had failed to provide relief. She had tenderness of the right sacroiliac joint. Diagnostic fluoroscopic-guided sacroiliac-joint injection with lidocaine did not produce symptomatic relief. Pelvic ultrasonography and magnetic resonance imaging showed septated multilocular hydatic cysts along the sciatic nerve. Surgical exploration noted multicystic lesions along the sciatic nerve woven to the nerve. Her low-back pain disappeared completely after the operation. She received oral albendazole for 6 months to prevent any recurrence of the disease and remains asymptomatic. CONCLUSION: Hydatid cyst can be included in the differential diagnosis of lumbar back pain, especially in the endemic areas.

Comparison of sciatic psoas compartment block and sciatic femoral 3-in-1 block for knee arthroscopy.

STUDY OBJECTIVES: To compare the clinical effectiveness of two peripheral nerve block techniques combined with sciatic nerve block: sciatic psoas compartment (SPC) and sciatic femoral 3-in-1 (SF 3-in-1) block. DESIGN: Prospective, randomized study. SETTING: Military medical academy hospital. PATIENTS: Thirty-six ASA physical status I patients, aged 20 to 33 years, undergoing elective knee arthroscopy. INTERVENTIONS: Patients having SPC block (n = 19) or SF 3-in-1 block (n = 17) received 40 mL of a mixture of solution containing 15 mL of 0.5% bupivacaine, 15 mL of 2.0% prilocaine, and 10 mL of 0.9% sodium chloride. In both groups, the sciatic nerve was blocked with 20 mL of the same solution. An intravenous bolus injection of fentanyl 0.1 mg was used if patients complained of pain. MEASUREMENTS AND MAIN RESULTS: None of the patients in the SPC group experienced pain owing to the applied tourniquet during the operation, whereas 7 patients from the SF 3-in-1 group (41.2 %) reported tourniquet pain. All SF 3-in-1 group patients but only 5 patients (26.3 %) in the SPC group required fentanyl during the operation. In addition, 7 patients in the SF 3-in-1 group required second doses of fentanyl. Patient satisfaction was significantly higher in the SPC group than in the SF 3-in-1 block group (P < 0.0001). CONCLUSIONS: Both SPC and SF 3-in-1 provided sufficient anesthetic efficacy for knee arthroscopy. However, SPC may be preferable to SF 3-in-1 block owing to better patient satisfaction and less requirement for opioid analgesics.

Transforaminal epidural steroid injection for the treatment of severe back pain caused by cement leakage during kyphoplasty procedure.

Kyphoplasty is a minimally invasive procedure that is increasingly used to treat pain caused by compression fractures of vertebral bodies. A 56-year-old woman who had a compression fracture on the vertebral body of L5 vertebra was admitted to the Algology Department with a severe low back and leg pain. Kyphoplasty was planned for pain relief. She suffered severe pain in her back and left leg immediately after the procedure because of a leakage of injected cement through the fracture line. After injection of triamcinolone and bupivacaine transforaminally into the L5-S1 anterior epidural space, her pain complaints ended. If radicular pain symptoms caused by cement leakage are secondary to a chemically mediated non-cellular inflammatory reaction, transforaminal epidural steroid injection should be useful.

Effect of septoplasty on left ventricular myocardial performance in patients with nasal septum deviation / Efeito da septoplastia no desempenho miocárdico ventricular esquerdo em pacientes com desvio de septo nasal

Methods: This prospective study consisted of 50 consecutive patients who underwent septoplasty due to symptomatic prominent C- or S-shaped nasal septal deviation. Transthoracic echocardiogarphy was performed in all patients before and 3 months after septoplasty. Calculated myocardial performance indices were compared. Results: Significantly higher left ventricular myocardial performance index (0.52 ± 0.06 vs. 0.41 ± 0.04, p < 0.001), longer isovolumic relaxation time (95.0 ± 12.5 vs. 78.0 ± 8.6 ms, p < 0.001), longer isovolumic contraction time (45.5 ± 7.8 vs. 39.5 ± 8.6 ms, p < 0.001), longer deceleration time (184.3 ± 32.5 vs. 163.6 ± 45.4 ms, p = 0.004), higher ratio of transmitral early to late peak velocities (E/A) (1.42 ± 0.4 vs. 1.16 ± 0.2, p = 0.006) and shorter ejection time (270.1 ± 18.3 vs. 286.5 ± 25.8 ms, p < 0.001) were observed before septoplasty when compared to values obtained 3 months after septoplasty. Left ventricular systolic ejection fraction was similar before and after septoplasty (63.8±2.8% vs. 64.6±3.2%, p =0.224). Conclusion: Septoplasty surgery not only reduces nasal blockage symptoms in nasal septal deviation patients but also may improve left ventricular performance. Thus, treatment of nasal septal deviation without delay is suggested to prevent possible future cardiovascular events.

Resumo Introdução: O desvio do septo nasal é a principal causa de obstrução das vias aéreas superiores. A obstrução crônica das vias aéreas superiores pode causar lesão miocárdica devido à hipóxia crônica. Os efeitos da septoplastia nas funções diastólica e sistólica do ventrículo esquerdo não são bem conhecidos. O índice de desempenho miocárdico é um parâmetro confiável e fácil de aplicar que reflete as funções cardíacas sistólica e diastólica. Objetivo: Investigar o efeito da septoplastia nasal no índice de desempenho miocárdico em pacientes com desvio de septo nasal. Método: Este estudo prospectivo consistiu em 50 pacientes consecutivos submetidos a septoplastia devido a desvio de septo nasal significativo sintomático em S ou C. A ecocardiogarfia transtorácica foi feita em todos os pacientes antes e 3 meses após a septoplastia. Os índices de desempenho miocárdico calculados foram comparados. Resultados: Um valor de indice de desempenho miocárdico ventricular esquerdo significantemente maior (0,52 ± 0,06 vs. 0,41 ± 0,04, p < 0,001), tempo mais longo de relaxamento isovolumétrico (95,0 ± 12,5 vs. 78,0 ± 8,6 ms, p < 0,001), tempo mais longo de contração isovolumétrica (45,5 ± 7,8 vs. 39,5 ± 8,6 ms, p < 0,001), tempo de desaceleração mais longo (184,3 ± 32,5 vs. 163,6 ± 45,4 ms, p = 0,004), maior razão de pico de velocidade transmitral precoce e tardia (E / A) (1,42 ± 0,4 vs. 1,16 ± 0,2, p = 0,006) e menor tempo de ejeção (270,1 ± 18,3 vs. 286,5 ± 25,8 ms, p < 0,001) foram observados antes da septoplastia quando comparados aos valores obtidos 3 meses após a septoplastia. A fração de ejeção sistólica do ventrículo esquerdo foi semelhante antes e após a septoplastia (63,8 ± 2,8% vs. 64,6 ± 3,2%, p = 0,224). Conclusão: A cirurgia de septoplastia não apenas reduz os sintomas em pacientes com desvio de septo nasal, mas também pode melhorar o desempenho ventricular esquerdo. Assim, o tratamento precoce do desvio de septo nasal é sugerido para prevenir possíveis eventos cardiovasculares futuros.

How important is the butyrylcholinesterase level for cesarean section?

OBJECTIVES: Butyrylcholinesterase (BChE), commonly known as pseudocholinesterase or non-neural cholinesterase, hydrolyzes neuromuscular blocker agents containing choline esters such as succinylcholine that is widely used in rapid sequence induction (RSI) for general anesthesia. The aim of this study is to compare plasma BChE levels and investigate the affects and relationship of succinylcholine on BChE levels in preeclamptic, gestational diabetic and healthy pregnants. STUDY DESIGN: We designed a prospective, controlled, pilot single-center study. Thirty (n=30) pregnant women who were scheduled for cesarean section under general anesthesia (refusal of regional anesthesia) with RSI involved. Group 1 included ten (n=10) preeclamptic pregnancies, Group 2 included ten (n=10) gestational diabetic (GD) pregnancies and Group 3 included ten (n=10) healthy pregnancies. MAIN OUTCOME MEASURES: BChE levels of all patients were measured prior to the initiation of cesarean section. Train-of-four recovery of 90% (TOF T1) was used to monitor the degree of neuromuscular block beginning from the administration of succinylcholine. RESULTS: No statistically significant difference was found between the groups comparing BChE levels and the duration between tracheal intubation and formation of TOF T1 (p>0.05). CONCLUSIONS: As similar results were gathered from normal and high-risk pregnancies (preeclamptic pregnancy or gestational diabetic pregnancy) who underwent cesarean section under general anesthesia, we believe that succinylcholine is still neuromuscular agent of choice in cesarean section.

Accuracy of caudal epidural injection: the importance of real-time imaging.

Caudal epidural steroid injections are often used for low back pain. Fluoroscopic guidance has been frequently cited as a requirement for this procedure. In this preliminary report, we demonstrate that fluoroscopic guidance for caudal epidural Tuohy needle placement without real-time imaging may result in inadvertent intravenous injection of the drug. We detected intravenous leakage of the drug in 4 cases of 10 when real-time fluoroscopic imaging was used. Thus, real-time imaging may be recommended in addition to routine fluoroscopic guidance for caudal epidural procedures, as it may improve efficacy and safety by assuring accurate drug deposition.

Comparison of the Macintosh and Airtraq Laryngoscopes in Endotracheal Intubation Success.

OBJECTIVE: Endotracheal intubation of patients is an effective method for controlling airway and breathing. However, laryngoscopy and endotracheal intubation is not easy in every case. There is a recent abundance of equipment used for controlling ventilation and intubation. Airtraq is one of those equipments. In this study, our main objective is to compare the success rates of the Airtraq and Macintosh (direct and classic) laryngoscopes in endotracheal intubation. METHODS: In this single-center, prospective, randomized, clinical study was performed on 80 patients who were operated under general anesthesia, ASA I-II, 18-65 years old. Patients were intubated using two different endotracheal intubation tools. Group A was intubated using the Macintosh (direct and classic) laryngoscope, meanwhile Group B was intubated using the Airtraq laryngoscope. Patients' snoring complaints, modified Mallampati scores, sternomental distances, thyromental distances, interincisor distance measurements and Cormack-Lehane (C-L) laryngoscopic classification, upper lip bite test results, intubation time, number of intubation attempts, maneuvers and techniques used for facilitating intubation and complications arising from intubation were recorded. RESULTS: There was a statistically significant difference between the groups in terms of C-L scores (p=0.041). In all, 8 patients in the Macintosh group, and 2 patients in the Airtraq group were C-L grade III. In intubation of the Airtraq group, only 3 patients required facilitating techniques, meanwhile in intubation of the Macintosh group 15 patients we had to use one or more facilitating maneuver. The rate of Mallampati scoring "difficult" was 4/6 in the Macintosh and 2/11 in Airtraq laryngoscopy groups (p=0.553). CONCLUSION: In cases with seemingly difficult intubations, we believe the Airtraq laryngoscope has an advantage over the Macintosh laryngoscope, owing to its better view of the oropharyngeal and glottic areas in addition to facilitating intubation in patients with limited head extension.
