RESUMEN

Abstract Background: Difficult or impossible face mask ventilation complicated with difficult tracheal intubation during anesthesia induction occurs in 0.4% of adult anesthesia cases, possibly leading to life-threatening complications. Because of such catastrophes, muscle relaxants have been recommended to be administered after confirming adequate face mask ventilation without a solid scientific validation of this principal. Methods: In this observational study, the ease of ventilation and the scores of direct laryngoscopy views before and after administration of cisatracurium were assessed in ninety young healthy adults, without anesthetic risks and without foreseen difficult intubation and who were scheduled for general elective surgeries. Results: Before muscle relaxation, 43 patients (48%) were Cormack Grade I, while the remaining 47 patients (52%) were either Cormack Grade II (28 patients, 31%) or Cormack Grade II (19 patients, 21%). Following muscle relaxation with cisatracurium, the number of patients with Cormack Grade I significantly increased from 43 patients (48%) to 65 patients (72%) (p = 0.0013). Only 1 patient out of 19 patients (5%) improved his Cormack grade from Grade III to Grade I while 16 out 19 patients (84%) improved their Cormack grade from Grade III to Grade II after the use of cisatracurium. The quality of face mask ventilation did not differ with and without muscle relaxants in all patients. Conclusion: The use of cisatracurium in healthy young adults undergoing general elective surgeries with no anticipated difficult endotracheal intubation had no effect on the quality of face mask ventilation despite resulting in a quantifiable improvement in the laryngeal view.


Resumo Justificativa: A ventilação difícil ou impossível via máscara facial complicada pela intubação traqueal difícil durante a indução da anestesia ocorre em 0,4% dos casos de anestesia em adultos, possivelmente leva a complicações fatais. Devido a tais catástrofes, recomendou-se que a administração de relaxantes musculares seja feita após a confirmação de ventilação adequada via máscara facial, sem uma validação científica sólida dessa conduta. Métodos: Neste estudo observacional, a facilidade de ventilação e os escores de visibilidade em laringoscopia direta antes e após a administração de cisatracúrio foram avaliados em 90 adultos jovens e saudáveis, sem riscos anestésicos e sem intubação difícil prevista, agendados para cirurgias eletivas gerais. Resultados: Antes do relaxamento muscular, 43 pacientes (48%) eram Cormack Grau I, enquanto os 47 (52%) restantes eram ou Cormack Grau II (28, 31%) ou Cormack Grade III (19, 21%). Após o relaxamento muscular com cisatracúrio, o número de pacientes com Cormack Grau I aumentou significativamente de 43 (48%) para 65 (72%) (p = 0,0013). Apenas um paciente (5%) dos 19 melhorou sua classificação de Cormack do Grau III para o Grau I, enquanto 16 dos 19 (84%) melhoraram suas classificações de Cormack do Grau III para o grau II após o uso de cisatracúrio. A qualidade da ventilação via máscara facial não diferiu com ou sem relaxantes musculares em todos os pacientes. Conclusão: O uso de cisatracúrio em adultos jovens saudáveis submetidos a cirurgias eletivas gerais sem intubação traqueal difícil prevista não teve efeito sobre a qualidade da ventilação via máscara facial, mesmo resultando em melhora quantificável da visibilidade da laringe.

RESUMEN

Noninvasive positive pressure ventilation is increasingly being used in emergency departments across Europe and North America. To our knowledge, no similar data are available from other countries. The aim of this study is to describe the current use of noninvasive positive pressure ventilation in the emergency departments of Lebanese hospitals. A structured and validated questionnaire was sent to all emergency departments in Lebanon. In Lebanon, 48.4% of emergency departments use noninvasive positive pressure ventilation. It is mostly used for patients with chronic obstructive pulmonary diseases and cardiogenic pulmonary edema. Bilevel and continuous positive airway pressures are the two most widely used modalities for noninvasive positive pressure ventilation. Face mask is the most used patient interface. The use of uniform protocols and training is lacking. Noninvasive positive pressure ventilation in Lebanese emergency departments is underused, with significant potential for improvements in its current practice.

RESUMEN

CONTEXT: Thoracic epidural and paravertebral blocks provide adequate analgesia for postoperative thoracotomy pain. Both procedures are usually performed percutaneously with considerable failure rates. A subpleural catheter placed in the space posterior to the parietal pleura and alongside the paravertebral area may provide superior postoperative pain relief. OBJECTIVE: To compare subpleural analgesia with thoracic epidural analgesia in patients undergoing thoracotomy. DESIGN: Randomised, double-blind study. SETTING: A tertiary care University Medical Centre between 26 June 2008 and 21 March 2011. PATIENTS: Forty-two patients scheduled for elective posterolateral thoracotomy. Patients with American Society of Anesthesiologists physical status ≥4, with a previous history of thoracotomy, on chronic pain medications or with a contraindication to receiving local anaesthetics or thoracic epidural block were excluded from the study. INTERVENTIONS: Patients were randomised to receive either subpleural analgesia or thoracic epidural analgesia for 24-h post-thoracotomy pain control. MAIN OUTCOME MEASURES: A visual analogue scale was used to assess pain at rest and on coughing during the first 24 h postoperatively and the incidence of hypotension was recorded. RESULTS: Patients who received subpleural analgesia had higher visual analogue scores at rest and on coughing than those who received thoracic epidural analgesia. Seven patients who started with subpleural analgesia were treated with thoracic epidural analgesia at a mean (SD) of 3.9 (4.8) h. The remaining 14 patients had a median (IQR [range]) visual analogue score of 5 cm (4-5 [3-6]) at rest and were maintained on subpleural analgesia until the end of the study. The visual analogue score at rest was <7 cm in all 21 patients who received thoracic epidural analgesia and none was switched to subpleural analgesia during the study. None of the patients in the subpleural analgesia group experienced hypotension compared with five of the 21 patients in the thoracic epidural analgesia group (P=0.047). CONCLUSION: Thoracic epidural analgesia is superior to subpleural analgesia in relieving post-thoracotomy pain.

RESUMEN

It has been previously suggested in the literature that with aging, degenerative changes as well as disc herniation start at the lower lumbar segments, with higher disc involvement observed in an ascending fashion in older age groups. We conducted a study to investigate this correlation between age and level of disc herniation, and to associate it with the magnitude of the Lumbar Lordotic Angle (LLA), as measured by Cobb's method. We followed retrospectively lumbosacral spine MRI's of 1419 patients with symptomatic disc herniation. Pearson's correlation was used in order to investigate the relationship between LLA, age, and level of disc herniation. Student's t-test was applied to assess gender differences. Young patients were found to have higher LLA (R = 0.44, P < 0.0001) and lower levels of disc herniation (R = 0.302, P < 0.0001), whereas older patients had higher level herniation in lower LLA group (mean LLA 28.6° and 25.4°) and lower level herniation in high LLA group (mean LLA 33.2°). We concluded that Lumbar lordotic Cobb's angle and age can be predictors of the level of lumbar disc herniation. This did not differ among men and women (R = 0.341, P < 0.0001).

RESUMEN

AIM: To evaluate the effect of posterior lingual lidocaine swab on patient tolerance to esophagogastroduodenoscopy, the ease of performance of the procedure, and to determine if such use will reduce the need for intravenous sedation. METHODS: Eighty patients undergoing diagnostic esophagogastroduodenoscopy in a tertiary care medical center were randomized to either lidocaine swab or spray. Intravenous meperidine and midazolam were given as needed during the procedure. RESULTS: Patients in the lidocaine swab group (SWG) tolerated the procedure better than those in the spray group (SPG) with a median tolerability score of 2 (1, 4) compared to 4 (2, 5) (P < 0.01). The endoscopists encountered less difficulty performing the procedures in the SWG with lower median difficulty scores of 1 (1, 5) compared to 4 (1, 5) in the SPG (P < 0.01). In addition, the need for intravenous sedation was also lower in the SWG compared to the SPG with fewer patients requiring intravenous sedation (13/40 patients vs 38/40 patients, respectively, P < 0.01). The patients in the SWG were more satisfied with the mode of local anesthesia they received as compared to the SPG. In addition, the endoscopists were happier with the use of lidocaine swab. CONCLUSION: The use of a posterior lingual lidocaine swab in esophagogastroduodenoscopy improves patient comfort and tolerance and endoscopist satisfaction and decreases the need for intravenous sedation.

RESUMEN

The risk of breast cancer has been associated with reproductive history. The purpose of this study was to determine the relationship between fertility drugs used in assisted reproductive procedures and the risk of breast cancer. We performed a literature search using the MEDLINE, the COCHRANE Library, and Scopus to identify studies linking breast cancer to fertility drugs. We excluded case series, case reports, and review articles from our analysis. The study populations included women who were treated for infertility with clomiphene, gonadotropins, gonadotropin-releasing hormones, or other unspecified fertility agents. We extracted information on study design, sample size, type of fertility drugs and number of treatment cycles, breast cancer incidence, and follow-up time from these studies. Eight case-control studies and fifteen cohort studies were included in the quantitative analyses. The Newcastle-Ottawa Quality Assessment Scales were used. Two investigators independently extracted study methods, sources of bias, and outcomes. We found that the risk of breast cancer was not significantly associated with fertility drug treatment. The follow-up periods were short in some of the studies analyzed in our study; however, we proceeded to test the trend in risk estimates across different durations of follow-up and found a trend for association using the nonparametric test; this was interpreted with caution in view of the lack of adjustment with other confounding factors. The current published data do not suggest higher risk of breast cancer in women who receive fertility treatment, but the lack of long-term follow up and the inherent weaknesses in some of the published studies have to be cautiously taken into account.

RESUMEN

BACKGROUND AND OBJECTIVE: Ventricular fibrillation is common after aortic cross-clamp release in patients undergoing open-heart surgeries. The aim of the study was to evaluate the efficacy of the prophylactic administration of 150 mg amiodarone by way of the pump 2 min before release of aortic cross-clamp in preventing ventricular fibrillation. METHODS: The present study is a prospective, randomized, controlled and blinded study performed at a teaching university hospital where 120 patients undergoing coronary bypass graft surgery were randomly assigned to three groups. Each group received either 150 mg of amiodarone or 100 mg lidocaine or isotonic saline by way of pump 2 min before release of the aortic cross-clamp. The frequency of occurrence of ventricular fibrillation and the subsequent required defibrillation counter shocks were determined in all groups. RESULTS: The frequency of occurrence of ventricular fibrillation was significantly higher in both the amiodarone (48%) and the control group (45%) as compared with the lidocaine group (20%) with no statistically significant difference between the amiodarone and the control groups. Furthermore, when ventricular fibrillation occurred, the percentage of patients requiring defibrillation counter shocks was significantly higher in both the amiodarone (58%) and control (61%) groups as compared with the lidocaine group (13%) with no difference between the amiodarone and the control groups, despite a significant decrease in the defibrillation counter shocks energy requirements in the amiodarone group. CONCLUSION: The present study showed no difference between amiodarone (150 mg) and placebo in preventing ventricular fibrillation after release of aortic cross-clamp. In addition, the use of lidocaine was able to reduce the incidence of ventricular fibrillation as compared with both amiodarone and placebo.

RESUMEN

BACKGROUND: The intubating laryngeal mask airway (ILMA) is used in the management of difficult intubation. Usually, a silicone wire-reinforced tube is inserted for tracheal intubation. Because the silicone wire-reinforced tube is expensive, alternatives, such as polyvinyl chloride (PVC) and posterior beveled Parker tubes, are worth considering. We compared the blind intubation success rates among the silicone wire-reinforced tube, the Parker tube, and the PVC tube, and identified laryngeal structures preventing tracheal intubations through the ILMA. METHODS: Sixty-three adult patients were randomized into three groups: Group I (n = 20) silicone wire-reinforced tube, Group II (n = 21) Parker tube, and Group III (n = 22) PVC tube. Demographic and clinical continuous data were compared with the analysis of variance with the Scheffé test for post hoc analysis. Frequencies and percentages were compared with the chi(2) test. RESULTS: Tracheal intubation was successful from the first attempt in 18 of 20 patients in Group I (silicone wire-reinforced tube), which was significantly higher than the success rate in either Group II (12 of 22 patients) (Parker tube) or Group III (10 of 21 patients) (PVC tube). With clockwise or anticlockwise rotation of the tracheal tube, the number of successful intubations did not change in Group I, but it increased to 19 of 22 patients in Group II and to 12 of 21 patients in Group III. The rate of successful intubation between patients in Group I (90%) and Group II (86%) was not significantly different after manipulation of the tracheal tube (P = 0.72). However, the rate of successful tracheal intubations in patients of Group III (57%) was significantly lower in comparison to patients in both Group I (P = 0.02) and Group II (P = 0.03). In 3 of the 22 patients of Group II and in 9 of the 21 patients of Group III in whom blind intubation was not possible, the obstruction was due to the epiglottis tubercule. CONCLUSIONS: Manipulation improved the success rate of intubation with the Parker tube through the ILMA rendering it a possible alternative to the silicone wire-reinforced tube.

RESUMEN

PURPOSE OF REVIEW: Worldwide 50-80 million people suffer from infertility. Assisted reproductive technology has provided a way of overcoming infertility and childlessness. The current article will focus on data linking infertility and its treatment to ovarian cancer. RECENT FINDINGS: Ovarian cancer risks associated with fertility drug treatment are encouraging, but not decisive. In view of the limited ability to evaluate drug effects on borderline tumors, given their rare occurrence, studies involving patient reports of prior drug exposures have noted an elevated risk of borderline tumors associated with fertility drugs. Nevertheless, the risk of invasive ovarian cancer appears to be restricted to those women who remain childless despite the infertility treatment. SUMMARY: As long as doubt persists, it might be advisable to reflect on a few clinical recommendations: identify high-risk infertile patients for ovarian cancer, investigate preexisting cancer before fertility treatment, inform patients regarding potential risks, obtain an informed consent, avoid exposure to long periods of ovulation induction cycles that are given before patients are referred for in-vitro fertilization and embryo transfer for women at greater risk and monitor women who have been treated with these drugs, especially those who failed to conceive, regularly and thoroughly.

RESUMEN

Laryngospasm is a common complication in pediatric anesthesia. In the majority of cases, laryngospasm is self-limiting. However, sometimes laryngospasm persists and if not appropriately treated, it may result in serious complications that may be life-threatening. The present review discusses laryngospasm with the emphasis on the different prevention and treatment modalities.

RESUMEN

PURPOSE OF REVIEW: Much has been published so far to describe and praise the benefits of mitral valve repair, and to compare it with valve replacement. Now, with mitral valve surgery in elderly people gaining greater acceptance worldwide, repair or replacement remains a controversial issue. This is especially true in the ageing population, in whom many of the complications associated with a mechanical valve can be avoided by using a bioprosthesis. This review will try to assess the latest views in the field and come up with possible answers to this ongoing question. RECENT FINDINGS: The causes of mitral regurgitation in this age group are separately reviewed and discussed in the light of our better understanding of the pathophysiology of the disease. Mitral surgery is recommended when the effective regurgitant orifice reaches 40 mm. Repair in degenerative disease seems to be feasible, with good long-term results. In chronic ischaemic regurgitation, the concept of a tethered 'normal valve' is changing. The 'poor' ventricle may be able to withstand surgery as long as the subvalvular apparatus is preserved; on the other hand, repair and replacement seem to have the same survival advantage in high-risk patients. SUMMARY: Mitral valve surgery is well tolerated in elderly people. Early intervention leads inevitably to better outcome. The majority of valvular disorders in this age group are amenable to repair, with good reproducible results. Replacement with a bioprosthesis remains a viable option for complex regurgitant jets.

RESUMEN

BACKGROUND: Postoperative abdominal and shoulder pain are the most common complaints after elective laparoscopic cholecystectomy. Postoperative pain is multifactorial in origin, and therefore multimodal therapy may be needed to optimize pain relief. METHODS: We conducted a double-blind study where patients were randomly allocated to 1 of 5 groups of 20 patients each. Statistical significance was considered P<0.05. Group 1 received 40 mL bupivacaine 0.25% intraperitoneal spray. Group 2 received 40 mL bupivacaine 0.25% intraperitoneal spray mixed with 200 mg ketoprofen. Group 3 received 40 mL bupivacaine 0.25% intraperitoneal spray and intravenous 200 mg ketoprofen. Group 4 received 200 mg ketoprofen intravenously. Group 5 was the control group. RESULTS: Demographic data were similar in the 5 groups. As compared with the control group, group 1 had significantly lower abdominal pain scores at 6 hours; group 2 at 0, 1, 2, and 6 hours; group 3 at 0, 1, 2, 6, 12, and 24 hours; and group 4 at 2 hours. Group 1 had significantly lower shoulder pain scores at 1 and 6 hours; group 2 at 0 and 6 hours; and groups 3 and 4 at 0, 1, and 6 hours. The number of patients requiring postoperative rescue analgesics and the incidence of postoperative vomiting were significantly lower in group 3 only. CONCLUSIONS: A multimodal approach to pain management following elective laparoscopic cholecystectomy is best achieved with a combination of 40 mL bupivacaine 0.25% intraperitoneal spray and 200 mg intravenous ketoprofen, achieving the least incidence of postoperative vomiting.

RESUMEN

Previous studies have indicated that music decreases intraoperative sedative requirements in patients undergoing surgical procedures under regional anesthesia. In this study we sought to determine whether this decrease in sedative requirements results from music or from eliminating operating room (OR) noise. A secondary aim of the study was to examine the relationship of response to intraoperative music and participants' culture (i.e., American versus Lebanese). Eighty adults (36 American and 54 Lebanese) undergoing urological procedures with spinal anesthesia and patient-controlled IV propofol sedation were randomly assigned to intraoperative music, white noise, or OR noise. We found that, controlling for ambient OR noise, intraoperative music decreases propofol requirements (0.004 +/- 0.002 mg . kg(-1) . min(-1) versus 0.014 +/- 0.004 mg . kg(-1) . min(-1) versus 0.012 +/- 0.002 mg . kg(-1) . min(-1); P = 0.026). We also found that, regardless of group assignment, Lebanese patients used less propofol as compared with American patients (0.005 +/- 0.001 mg . kg(-1) . min(-1) versus 0.017 +/- 0.003 mg . kg(-1) . min(-1); P = 0.001) and that, in both sites, patients in the music group required less propofol (P < 0.05). We conclude that when controlling for ambient OR noise, intraoperative music decreases propofol requirements of both Lebanese and American patients who undergo urological surgery under spinal anesthesia.
