Effects of blood flow restriction in large and small muscle groups / Efeitos da restrição do fluxo sanguíneo em grupamentos musculares grandes e pequenos / Efectos de la restricción del flujo sanguíneo en grupos musculares grandes y pequeños

ABSTRACT Introduction It is known that strength training brings improvements in health and sports performance by causing muscle hypertrophy and increased strength, as well as modifying some hemodynamic and physiological factors. Several strength training methodologies have been developed, one of which is vascular occlusion. There are few studies with large muscle groups due to poor adherence to the training style and the fact that vascular occlusion of large muscle groups is more difficult. Objective To verify and compare the hemodynamic effects of exercise with and without vascular occlusion in different muscle groups. Methods Quantitative crossover study, with cross-sectional and field procedures. The sample consisted of 10 physically active healthy male and female subjects between 18 and 30 years of age. With the cross-over design, all the volunteers participated in 3 groups: intervention with vascular occlusion, intervention without vascular occlusion and the control group. Results Overall, lactate and cholesterol remained elevated after 15 minutes of recovery and blood glucose and blood pressure did not vary among the groups. Conclusion Vascular occlusion training is an effective method for manipulating hemodynamic variables. Evidence level II; Clinical study.

Pattern of dynamic intestinal obstruction in adults

Background: Pericardial effusion in clinical practice is commonly under diagnosed or missed especially minimal to moderate effusion. Aim and objectives: To study the clinical and etiological profile of pericardial effusion and to recognize radiological, electrocardiographic and echocardiographic features that are characteristic of pericardial effusion and to analyze pericardial fluid in various etiologies. Materials and methods: It was prospective study in patients presenting with pericardial effusion in department of Medicine and Cardiology. Total of 30 patients who presented with pericardial effusion based on clinical criteria and confirmed by echocardiography were included in the study. Results: The causes of pericardial effusion in this study were Tuberculosis (33.33%), Uremia (20%), Viral /Idiopathic (16.67%), Bacterial (10%), Malignancy (10%), Hypothyroidism (3.33%), and post MI with ischemic cardiomyopathy (3.33%), SLE (3.33%). 3 cases (10%) were HIV positive among viral causes,1 patient had tuberculous pericarditis. ECG findings of low voltage complexes were present in 90% of patients and electrical alternans was seen mainly in tamponade cases. Chest X-ray finding of cardiomegaly was present in 90% patients with pleural effusion in 13.3% patients. ADA levels elevated in all 10 patients of tuberculous effusion with 100% sensitivity and among them smear for AFB was positive in 3 patients. Increased levels of ADA>60U/L was associated with increased incidence of effusive constrictive pericarditis in TB effusion. Pericardial fluid IFN-ᵞ increased greater than 200 pg/L, tuberculous etiology showed 100% sensitivity and specificity. In all 10 patients of M Manjusha, B. Manoj Kumar, N. Venkat Rajaiah, P. Narayana. Study of characteristic of pericardial effusion and to analyze pericardial fluid in various etiologies. IAIM, 2017; 4(10): 221-229. Page 222 2Dimensional echocardiographic findings of right atrial, right ventricular collapse and left atrial collapse was seen predominantly in tamponade cases. Pericardiocentesis showed hemorrhagic effusion in malignancy and uremia, serous and serofibrinous in tuberculosis and purulent in pyogenic effusion. In 3 cases of pyogenic effusion, culture revealed Staphylococcus aureus in 2 patients and Klebsiella pneumonia in 1 patient. Among 3 cases of HIV, one patient had ADA >40 and smear for AFB positive suggesting tuberculous etiology and other 2 cases were directly due to HIV. In HIV with tubercular effusion the patient presented with cardiac tamponade. Conclusions: ADA>40U/L is diagnostic of tuberculous effusion which showed 100% sensitivity and specificity. Increase of ADA>60 U/L is associated with effusive constrictive pericarditis which has poor prognosis. IFN-ᵞ is increased >200pg/l in all patients of tuberculous etiology showing 100% sensitivity and specificity

Low dose fentanyl attenuates hypertension but not tachycardia duringlaryngoscopy and trachealintubation in a three arm study.

Background: Tracheal intubation may induce; hypertension, tachycardia, and/or arrhythmia. Fentanyl is a frequently used opioid that joins with hypnotic agents to diminish hemodynamic responses to tracheal intubation. Furthermore, lidocaine has a suppressive effect on the circulatory responses in patients undergoing laryngoscopy and tracheal intubation. However, intravenous lignocaine has shown variable results and large doses of fentanyl causes hypotension and cough. We compared the effectiveness of intravenous lignocaine 1.5 mg/kg bolus and intravenous fentanyl 2 mcg/kg bolus in attenuating the sympathetic response to laryngoscopy and tracheal intubation. Materials and methods: One hundred and fifty ASA physical status I or II patients undergoing elective, non-cardiac procedures were randomized, to one of the three treatments such as either normal saline or lignocaine 2 mg/kg or fentanyl 2 mcg/kg. Intubation was carried out 3 minutes after administration of these study drugs. Patients received Midazolam before induction, and Thiopental, Rocuronium during anesthesia. The heart rate, blood pressure and SPO2 were recorded a day before (B), before intubation (0) at 1 2 3 4-5 minutes after induction. Results: Tachycardia (HR>100 beats/min) after intubation was statistically similar across 85% (17/20), 75% (15/20) and 55% (11/20) saline, lignocaine, and fentanyl respectively (p>0.05). Hypertension (SBP > 180 mmHg) was seen in 80% (16/20), 70% (14/20) and 40% (8/20) with saline, Valluri Anil Kumar, Vaddineni Jagadish, Netra Chavali. Low dose fentanyl attenuates hypertension but not tachycardia during laryngoscopy and tracheal intubation in a three arm study. IAIM, 2016; 3(4): 72-77. Page 73 lignocaine and fentanyl respectively. The incidence of hypertension with fentanyl was significantly (p<0.05) lower than saline; however, such a meaning was not observed with lignocaine. Conclusion: Low dose of fentanyl prevented hypertension but not tachycardia as compared to normal saline; on the other hand, lignocaine did not attenuate cardiovascular responses during laryngoscopy and tracheal intubation.

The ED50 of dexmedetomidine for suppressing cardiovascular responses to placement of laryngeal mask in female patients with induction of propofol / 实用医学杂志

Objective To determine the ED50 of dexmedetomidine for suppressing cardiovascular responses to placement of laryngeal mask airway (LMA) in patients undergoing gynecological laparoscopic surgery with induction of propofol. Methods ASA I or II Patients aged 18 to 55 undergoing elective gynecological laparoscopic surgery were enrolled. After an bolus dose of dexmedetomidine over 10 min , anaesthesia was induced with target-controled propofol, and then bolus of vecuronium of 0.1 mg/kg was injected when the BIS was between 45 and 55. LM palcement was performed 3 minutes after vecuronium injection. The modified Dixon ’ s up-and-down method was used to determine the bolus dose of dexmedetomidine , starting from 1.0 μg/kg (step size:0.1 μg/kg). Cardiovascular response was defined as an increase in SBP and/or HR by 15% of baseline within 2 min after placement of LMA. The test ended after at least 7 crossovers ( successive ‘response’ or ‘non-response’) were obtained. Probit analysis was used to calculate ED50, ED95 and 95% confidence interval (CI). Results The ED50 and ED95 (95% confidence interval) of dexmedetomidine for suppressing cardiovascular responses to placement of LMA was 0.65 μg/kg (0.44-0.80) μg/kg and 0.94 μg/kg (0.79-2.47) μg/kg. Conclusion Under induction of target-controled propofol , the ED50 of dexmedetomidine is 0.65 μg/kg for suppressing cardiovascular responses to placement of LMA in female patients.

Cardiovascular responses in elderly hypertensive patients with discopotracheal intubation / 实用医学杂志

Objective To compare cardiovascular responses of intubations by Discopo and Macintosh laryngoscope in elderly patients with hypertension. Methods Sixty elderly hypertensive patients with ASAⅡ~Ⅲundergoing elective surgery were equally randomized into two groups. After induction of general anesthesia , orotracheal intubation was performed with Discopo or Macintosh. The Mean arterial pressure (MBP) and heart rate (HR), as while as Electrocardiogram (ECG) and Blood oxygen saturation (SpO2), were recorded before (baseline values) and at 1,3,5 minutes after intubation(post-induction values). The rate of one-time successive intubation,intubation time and complication were also recorded. Results Compared with the macintosh group, the rate of one-time successive intubation was higher and the intubation time was shorter in the Discopo group (P< 0.05, respectively),with no complications. Compared with T0,MBP and HR at T2 in the two groups and T3 in the Macintosh group increased significantly (P < 0.05). Compared with the Macintosh group,MBP and HR at T2,T3 of the Discopo group decreased significantly (P < 0.05). Conclusion Little effect of tracheal intubation with Discopo on cardiovascular response was observed in elderly hypertensive patients.

Objective: To observe the effect of lidocaine aerosol on preventing cardiovascular response and sore throat, hoarseness in the patients with double lumen tube to orotracheal intubation. Methods: 60 selective patients (ASA I - II) scheduled for lung lobectomy were randomly divided into 3 groups, with 20 cases in each group. Lidocaine aerosol (group A) and Saline as a control (group B and group C) were given to spray. After routine induction, the glottis was exposed and 3 press lidocaine aerosol were given in group A, while group B and C were given saline. Patients in group C were received additional 0.5mg/kg of propofol and 1μg /kg of fentanyl intravenously before the exposure of glottis. HR, SBP, DBP, HR*SBP were monitored and recorded at the time points of pre-induction (T0), immediately pre-intubation (T1), 1 min (T2), 3 min (T3), 5min (T4), 10min (T5) after intubation. Cases of sore throat and hoarseness were also recorded at the point of 1h, 6h, 24h postoperation. Results: Compared with T0, values of HR, SBP and RPP at T1 were significantly decreased after inductionP<0.05. Values of HR, SBP, RPP in group B and C were higher than that in group A at T2 and T3P<0.05. SBP was significantly decreased at T4 and T5 in group CP<0.05. Cases of postoperative sore throat and hoarseness in group A were significantly lower than that in group B and CP<0.05. Conclusion: Lidocaine aerosol can effectively suppress cardiovascular responses caused by double lumen tube intubation, decrease the dose of induction drugs, reduce the incidence of postoperative sore throat and hoarseness.

The comparison of intranasal and intravenous dexmedetomidine on the adverse reactions of tracheal extubation during wake up of general anesthesia / 中国医师进修杂志

Objective To compare the adverse reactions of intranasal and intravenous dexmedetomidine on tracheal extubation during wake up of general anesthesia.Methods One hundred and twenty patients who ASA Ⅰ or Ⅱ grade were divided into four groups (each 30 patients) by random digits table method.The patients in intravenous group were given 0.5 μ g/kg intravenous dexmedetomidine (diluted to 10 ml by 0.9％ sodium chloride,intravenous injection slowly,≥30 s).The patients in intranasal group 1 were given 0.5 μg/kg intranasal dexmedetomidine.The patients in intranasal group 2 were given 0.8 μg/kg intranasal dexmedetomidine.The patients in control group were given intravenous 0.9％ sodium chloride.The systolic blood pressure(SBP),mean arterial blood pressure (MAP),heart rate were compared among groups.Eyes open time and extubation time,the rate of cough and the degree during extubation were compared too.Results The SBP,MAP,heart rate in intravenous group,intranasal group 1 were significantly higher than those in basal state (P ＜ 0.05).The SBP,MAP,heart rate at different time in intranasal group 2 had no significant difference (P ＞ 0.05).The SBP,MAP,heart rate before extubation and after extubation for 3 min in control group were significantly higher than those in intravenous group,intranasal group 1 and intranasal group 2 (P ＜ 0.05).Eyes open time and extubation time among four groups had no significant difference(P ＞0.05).The rate of cough,restlessness and 3 scores of degree before extubation in intravenous group,intranasal group 1 and intranasal group 2 were significandy lower than those in control group [43％ (13/30),50％(15/30),47％(14/30) vs.70％ (21/30); 17％(5/30),23％(7/30),20％(6/30) vs.43％(13/30);53％ (16/30),60％ (18/30),50％ (15/30) vs.80％ (24/30)] (P ＜ 0.05).Conclusions Either intravenous or intranasal dexmedetomidine can effectively prevent the stress reaction during extubation,decrease the degree of restlessness and cough.Intranasal dexmedetomidine(0.8 μ g/kg) is more effective and safe.

Effect of rest interval on cardiovascular responses after resistance exercise / Efeito do intervalo de recuperação nas respostas cardiovasculares pós-exercício de força

OBJECTIVE: To analyze the acute effect of rest interval length on cardiovascular response after resistance exercise. METHODS: Twenty young eutrophic men (23.9 ± 0.7 years;23.8 ± 0.5 kg/m²) performed two experimental sessions in a random order: resistance exercise with a 30-second (I30) and with a 90-second (I90) rest interval between sets. Both sessions included five exercises with 50% of the one-repetition maximum. Before and 24 hours after the experimental sessions, systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), and rate-pressure product (RPP) were obtained. RESULTS: The SBP, DBP and RPP responses were similar between the I30 and I90 sessions (p>0.05), while the HR after I30 was significantly higher than after I90 (p<0.01) for the first hour after exercise. The cardiovascular responses during the first 24 hours were similar between both sessions (p>0.05). CONCLUSION: Different recovery intervals did not promote post-exercise hypotension, however, a short rest interval increases heart rate for 1 hour after exercise. In addition, within 24 hours of the responses were similar between groups.

OBJETIVO: Analisar o efeito agudo do intervalo de recuperação na resposta cardiovascular após o exercício de força. MÉTODOS: Vinte homens jovens eutróficos (23,9 ± 0,7 anos; 23,8 ± 0,5 kg/m²) realizaram duas sessões experimentais em ordem aleatória: exercício de força com 30 segundos (I30) e com 90 segundos (I90) de intervalo de recuperação entre séries. As sessões incluíram cinco exercícios com 50% de uma repetição máxima. Antes e 24 horas após as sessões experimentais, pressão arterial sistólica (PAS), pressão arterial diastólica (PAD), frequência cardíaca (FC) e duplo produto (DP) foram obtidos. RESULTADOS: A resposta da PAS, PAD e DP foi similar entre os grupos (p>0,05), enquanto a FC após a I30 foi significantemente maior que a I90 (p<0,01) na primeira hora pós-exercício. As respostas cardiovasculares durante as 24 horas foram similares entre as sessões (p>0,05). CONCLUSÃO: Diferentes intervalos de recuperação não promoveram hipotensão pós-exercício, entretanto, um curto intervalo de recuperação aumentou a FC por uma hora pós-exercício. Além disso, nas 24 horas seguintes as respostas foram similares entre os grupos.

Variáveis cardiovasculares durante e após a prática do VÍDEO GAME ativo "Dance Dance Revolution" e televisão / Cardiovascular responses during and after active VIDEO GAME and television

As doenças cardiovasculares (DCVs) estão entre as principais causas de morte no mundo e os processos patológicos associados com o seu desenvolvimento têm início na infância. O objetivo do estudo foi analisar e comparar as respostas de variáveis cardiovasculares durante e após a prática de vídeo game interativo e televisão. A amostra foi composta de oito crianças saudáveis (9,8 ± 0,5 anos; 30,1 ± 3,4kg; 133,3 ± 13,6 cm; 17,4 ± 4,7 kg/m²). O estudo consistiu de três sessões das quais a 1ª destinou-se a avaliação antropométrica e familiarização (FAM) com os equipamentos e o laboratório, e as demais sessões foram realizadas em ordem randomizada, sendo 30 minutos de Dance Dance Revolution (DDR), nível iniciante; e 30 minutos de televisão (TV) em que dois desenhos infantis (Ben 10 e Bob Esponja) foram apresentados. Durante as sessões foram aferidas a freqüência cardíaca (FC), Pressão Arterial Sistólica (PAS) e Pressão Arterial Diastólica (PAD) aos 10 minutos de repouso sentado, bem como aos 10, 20 e 30min de atividade (DDR ou TV) e aos 2, 10, 20, 30 e 40 min após finalização das atividades. Para a análise estatística foi verificada a distribuição normal dos dados pelo teste de Kolgomorov-Smirnov, ANOVA one-way, com Post Hoc de Scheffé para comparação entre sessões e ANOVA para medidas repetidas na comparação entre os momentos de cada sessão que foram testados. O nível de significância adotado foi p≤0,05 (ESTATÍSTICA 6.0). Aumento significativo dos valores de FC, PAS e PAM durante o DDR (30 min: 110 bpm, 116 e 89 mmHg) foram observados quando comparados com a TV (30 min: 86 bpm, 102 e 70 mmHg) respectivamente. Foi observada uma tendência de queda da FC e PAS aos 40 min de recuperação após sessão DDR, bem como uma tendência de elevação da FC, PAS, PAD e PAM após TV quando comparadas ao repouso, porém estas não foram significantes (p>0,05). Concluímos que o vídeo game interativo DDR pode ser uma alternativa interessante para aumentar o nível de atividade física, podendo trazer benefícios cardiovasculares pós-exercício. Caso estes valores de PAS se mantenham inferiores nessas crianças ao longo do dia, podemos considerar o uso desse instrumento na proteção cardiovascular durante a infância, podendo impactar positivamente na atenuação de eventos cardiovasculares na idade adulta futura, o que seria muito importante para a saúde pública.

Cardiovascular diseases (CVDs) are the leading cause of death worldwide and the pathological processes associated with their development in the early childhood. The objective of this study was to investigate the cardiovascular responses during and after the practice of video game interactive and television. The sample consisted of eight healthy children (9.8 ± 0.5 years, 30.1 ± 3.4 kg, 133.3 cm ± 13.6, 17.4 ± 4.7 kg/,). The study consisted of three sessions, where the 1st was FAM - for anthropometric measurement and procedures familiarization, and the other sessions, were performed in randomized order; DDR - Dance Dance Revolution: the volunteers realized 30 min in the beginner level; TV - 30 min watching a children's cartoon (Ben 10 and Sponge Bob). The heart rate (HR), systolic (SBP) and diastolic (DBP) blood pressure were measured at rest and during the 10th, 20th and 30th minutes of activity and recovery in the 2nd 10th, 20th, 30th and 40th min. Statistical analysis was checked for normal distribution of data by Kolgomorov-Smirnov test, ANOVA, one-way MANOVA with post hoc Scheffé for comparison between sessions, ANOVA repeated measures, comparing the times of each session. The significance level was p ≤ 0.05 (ESTATÍSTICA 6.0). The results show a significant rise in HR, SBP and MAP during the DDR (30min: 110bpm, 116.3 and 89.6 mmHg) compared to the TV (30min: 86.7 bpm, 102 mmHg and 70.3mmHg). There was a downward trend in HR and SBP at 40 min of recovery after session DDR, as well as an upward trend in HR, SBP, DBP, and MAP after TV when compared to the rest, but these were not significant (p>0,05). We conclude that video game is an interesting alternative of active playing, which might bring cardiovascular benefits. If these BP values be maintained throughout the day during childhood, we may expect a better health during adulthood what, in turn, may be important for public health.

Objective To observe the impacts on the patients with cardiovascular responses when applying propofol combined with different dose of remifentanil in tracheal intubation without the use of muscle relaxants for anesthesia induction. Methods Sixty patients undergoing selective general anesthesia operation of ASA Ⅰ -Ⅱ non-heart and brain surgery were divided into three groups by random digits table, and 20 cases for each group. Target-controlled infusion of remifentanil with respective plasma concentration of 2 ng/ml (group Ⅰ ), 3 ng/ml (group Ⅱ ) and 4 ng/ml (group Ⅲ). Target-controlled infusion of propofol after infusion of remifentanil for 5 min (3 μg/ml of plasma target concentration). The mean arterial pressure (MAP),heart rate (HR), intubation conditions and success rate of patients in different groups before induction(T1), at the beginning moment of propofol(T2),at the immediate moment before tracheal intubation (T3) and at the time of 1 min after tracheal intubation (T4). Results The grade of tracheal intubation was (10.5 ±2.9), (7.6 ±2.3), (5.8 ± 1.2) scores and the success rate of the first intubation was 50%( 10/20), 80%(16/20), 100%(20/20) in group Ⅰ ,Ⅱ and Ⅲ , there were significant differences among three groups (P＜ 0.05),group Ⅲ was superior to group Ⅰ and Ⅱ (P＜0.05). Comparing T2 and Tj,HR in group Ⅱ and Ⅲ slowed down significantly ( P ＜ 0.05), and in group Ⅲ slowed down more significantly (P＜0.05). Comparing T4 and T3,HR in group Ⅰ and Ⅱ quickened significantly, and group Ⅰ was higher than group Ⅱ and Ⅲ (P＜ 0.05). Comparing T3 and T2,MAP decreased significantly among three groups,comparing T4 and T3, MAP increased significantly in group Ⅰ which was higher than that in group Ⅱ and Ⅲ (P ＜ 0.05). Conclusions Without the use of muscle relaxants, propofol combined with remifentanil for 3-4 ng/ml can better restrain the tracheal intubation stress responses and won't cause significant cycle inhibition. They benefit to maintain the smooth intubation process of anesthesia induction.

O objetivo deste estudo foi avaliar os efeitos cardiovasculares agudos doexercício resistido (ER) em idosas com hipertensão estágio I. Participaram 24 hipertensas (63,7 ± 3,7 anos), submetidas a uma sessão de ER, constituída por oito estações (três séries, 12 repetições, 50% 1 RM). A frequência cardíaca (FC), a pressão arterial sistólica (PAS) e a diastólica (PAD) foram mensuradas anteriormente ao início dos exercícios (A), imediatamente após a quinta estação (B) e 10 min. após a sessão de exercícios (C). Anova de medidas repetidas e post-hoc Tukey (p < 0,05) foram utilizados. Os resultados demonstraram aumento significativo na PAS, PAD e FC (p < 0,05) entre as condições A e B. Subsequentemente, na condição C, em PAS e PAD houve decréscimo significante em relação à condição B (p < 0,05), porém somente PAD reduziu significativamente para acondição A (p < 0,05). Apesar das modificações cardiovasculares agudas associadas ao ER, propensão positiva a hipotensão somente é verificada em relação à PAD.

The aim of this study was to evaluate the effect of acute cardiovascularresponses of resistance exercise (RE) on stage I hypertensive elderly women. Twenty four hypertensive women (63.7 ± 3.7 years) were subjected a session of RE, with eight stations (3 sets, 12 repetitions, 50% 1 RM). The heart rate (HR), systolic blood pressure (SBP) andblood pressure (DBP) were measured before the exercise sessions (A), immediately after the fifth station (B), and 10 minutes after the exercise sessions (C). Repeated measuresAnova and post-hoc Tukey test (p < 0.05) were performed. The results demonstrated significant increase in SBP, DBP and HR (p < 0.05) between the A and B conditions. Subsequently, SBP and DBP decreased significantly for the C condition as compared to theB condition (p < 0.05); however, only DBP decreased significantly for the A condition (p < 0.05). Although the results demonstrated that acute cardiovascular modifications areassociated with RE, hypotensive effects were only verified on DBP.

The sample consisted of 53 volunteers of both genders who were all sedentary, at the age of 64.28±4.7 years old, fair skin, with HBP. The blood pressure levels, cardiac frequency (CF), body weight (Kg), BMI and body fat percentage (BF%) were analyzed before, during and after the period of exercises. The training protocol consisted of exercise sessions divided into 20 minutes of aerobic activity and 40 minutes of dynamic resistance exercises, three times a week, during a period of six months. Results showed a significant difference in relation to the BF%, followed by a linear reduction in the Average Blood Pressure (ABP) and CF, as well as an improvement in important morphofunctional parameters.

Cardiovascular responses between post myocardial infarction patients with different levels of ST segment depression during exercise / 中国康复医学杂志

Objective: To investigate selected cardiovascular responses of post myocardial infarction patients(PMIP)during exercise within the context of different levels of ST segment depression. Method: Forty-six male recent PMIP performed a graded exercise test on a motorized treadmill during which time blood pressure and heart rate were measured and a 12 lead electrocardiogram (ECG) was monitored continuously. They were then subdivided into those ST segment depression ＜1.0 mm at exercise stage Ⅱ (group 1) and those who had ST segment depression ＞1.0 mm at this stage (group 2). Result: The results showed that the patients with a larger degree of ST segment depression at the given work load exhibited higher a value of rate-pressure product (RPP).Conclusion: RPP may be of particular value in estimating the clinical response to exercise when ECG monitoring is not available.

A Comparison of Hemodynamic Changes after Endotracheal Intubation by using the Bonfils Intubation Fibrescope and the Laryngoscope / 대한마취과학회지

BACKGROUND: The hemodynamic changes associated with orotracheal intubation may result from direct laryngoscopy and the endotracheal intubation. This study evaluated and compared the cardiovascular changes after either Bonfils intubation fibrescope or conventional laryngoscopic endotracheal intubation. METHODS: Sixty patients, aged 20 to 30 years, were randomly allocated into two groups, the Bonfils intubation fibrescope group (BF group, n = 30) and conventional intubation using a rigid laryngoscope (LS group, n = 30). Bonfils intubation fibrescope or laryngoscopic oral endotracheal intubation was performed after inducing anesthesia. The systolic and diastolic arterial pressures, heart rate, peripheral oxygen saturation and intubation time were recorded before and after orotracheal intubation. RESULTS: In both groups, the systolic and diastolic arterial pressures increased significantly after endotracheal intubation. The heart rate increased significantly after the induction of anesthesia in both groups. However, the arterial blood pressure, heart rate and intubation time were similar in both groups. CONCLUSIONS: The use of a Bonfils intubation fibrescope does not modify the hemodynamic response associated with endotracheal intubation compared with conventional laryngoscopy.

The Relation of Trait anger and Anger Expression to Cardiovascular Responses and Depression in Middle-aged Korean Women / 간호학회지

PURPOSE: This study was designed to examine the relation of trait anger and anger expression to blood pressure, cholesterol, and depression in middle-aged Korean women. METHODS: This descriptive correlational design was conducted using a convenient sample taken from the health center of K University Hospital located in Kyungki province, Korea. The subjects were 252 women aged 40 to 64 years. Spielberger's state trait anger expression inventory - Korean version and Beck's depression inventory were used for measuring trait anger, state anger, anger expression and depression. Data was analyzed by descriptive statistics, t-test, Pearson correlation, two-way ANOVA, and cluster analysis using a pc-SAS program. RESULTS: The anger expression types by cluster analysis were Anger out/in type, Low anger expression type, and Anger control type. The level of cholesterol and depression were significantly higher in women with high anger in and high trait anger. In addition, the level of depression was significantly higher in women with a high anger temperament. CONCLUSIONS: Trait anger and anger in might be related to cholesterol and depression in women. However, this study does not reveal the relation between blood pressure and trait anger and anger expression.

Effects of Laryngeal Mask Insertion on Cardiovascular Responses during Cesarean Section / 대한마취과학회지

In 1983, Brain introduced laryngeal mask as a new airway. Laryngeal mask bave many advantages of easy insertion without laryngoscope and muscle relaxants, minimal cardiovascular responses, decreasing damages of larynx and pharynx and also useful in difficult intubation or emergency airway care. We studied cardiovascular responses of parturients and Apgar score of neonates during tracheal intubation(Group I) and laryngeal mask insertion(Group II), After tracheal intubation or insertion of laryngeal mask, blood pressure(systolic, diastolic and mean) and heart rate were measured for 5 minutes at 1 minute interval. The results were as follows: 1) There were significant increase in systolic, diastolic, mean arterial pressure and heart rate in both groups, but degree of increase was less in laryngeal mask group. 2) The Apgar scores of the neonates did not differ significantly, 1 minute Apgar score was up 8 in both group. It is concluded that insertion of laryngeal mask is beneficial to parturients than use of laryngoscope and tracheal intubation to avoid harmful cardiovascular responses in the management of airway during cesarean section.
