ABSTRACT
Aim & Objectives: To compared the effect of ketamine and combination of ketamine plus dexamethasone on the duration of postoperative analgesia and to evaluate the effect of dexamethasone on postepidural backache and other complications. Methods: 50 patients (ASA I and II) posted for elective surgery of lower limb in orthopedics, were divided at random into two groups of 25 each. Patients in group I received Inj. Ketamine HCl 0.3 mg/kg diluted in 10 ml normal saline while patients in group II received ketamine HCl 0.3 mg/kg and dexamethasone 8 mg diluted in 10 ml normal saline postoperatively through epidural catheter. The relief of pain and perioperative sequelae were compared. Results: Groups were compared with respect to quality of epiduralanaesthesia and pain relief as felt by the patient. The quality of epidural anaesthesia was found adequate in 80% cases of group 2 and 76% cases of group 1. Pain relief was 20% excellent and 76% good in group 2 and 12% excellent and 68% good in group 1. In group I the mean duration of pain relief after epidural injection of ketamine 0.3 mg/kg was 363.91±180.94 min and in group II after epidural injection of ketamine 0.3 mg/kg with dexamethasone 8 mg was 582.63±182.03 min. These values differ markedly and are statistically highly significant (p<0.001). Conclusion: Ketaminecan be used epidurally safely for rapid onset and is effective for prolonged postoperative analgesia with minimum side effects and high acceptability. The duration can be further prolonged with the addition of dexamethasone and the incidence of postepidural backache is also minimised with dexamethasone.
ABSTRACT
Since the first use of the flexible fibreoptic bronchoscope, a plethora of new airway equipment has become available. It is essential for clinicians to understand the role and limitations of the available equipment to make appropriate choices. The recent 4th National Audit Project conducted in the United Kingdom found that poor judgement with inappropriate choice of equipment was a contributory factor in airway morbidity and mortality. Given the many modern airway adjuncts that are available, we aimed to define the role of flexible fibreoptic intubation in decision-making and management of anticipated and unanticipated difficult airways. We also reviewed the recent literature regarding the role of flexible fibreoptic intubation in specific patient groups who may present with difficult intubation, and concluded that the flexible fibrescope maintains its important role in difficult airway management.

BACKGROUND AND OBJECTIVES: Aortic stenosis increases perioperative morbidity and mortality, perioperative invasive monitoring is advised for patients with an aortic valve area <1.0 cm2 or a mean aortic valve gradient >30 mm Hg and it is important to avoid hypotension and arrhythmias. We report the anaesthetic management with continuous spinal anaesthesia and minimally invasive haemodynamic monitoring of two patients with severe aortic stenosis undergoing surgical hip repair. CASE REPORT: Two women with severe aortic stenosis were scheduled for hip fracture repair. Continuous spinal anaesthesia with minimally invasive haemodynamic monitoring was used for anaesthetic management of both. Surgery was performed successfully after two consecutive doses of 2 mg of isobaric bupivacaine 0.5% in one of them and four consecutive doses in the other. Haemodynamic conditions remained stable throughout the intervention. Vital signs and haemodynamic parameters remained stable throughout the two interventions. CONCLUSION: Our report illustrates the use of continuous spinal anaesthesia with minimally invasive haemodynamic monitoring as a valid alternative to general or epidural anaesthesia in two patients with severe aortic stenosis who are undergoing lower limb surgery. However, controlled clinical trials would be required to establish that this technique is safe and effective in these type or patients.
JUSTIFICATIVA E OBJETIVOS: A estenose aórtica aumenta a morbidade e mortalidade no período perioperatório. A monitoração invasiva no perioperatório é recomendada para pacientes com área valvar <1,0 cm2 ou gradiente médio >30 mm Hg, além de ser importante evitar a hipotensão e arritmias. Relatamos o manejo anestésico com o uso de raquianestesia contínua e monitoração hemodinâmica minimamente invasiva em duas pacientes com estenose aórtica grave, submetidas à cirurgia de reparação do quadril. RELATO DE CASO: Duas pacientes com estenose aórtica grave foram programadas para cirurgia de reparação de fratura de quadril. Raquianestesia contínua com monitoração hemodinâmica minimamente invasiva foi usada para o manejo anestésico de ambas as pacientes. A cirurgia foi realizada com sucesso após duas doses consecutivas de 2 mg de bupivacaína isobárica a 0,5% em uma das pacientes e quatro doses consecutivas na outra. As condições hemodinâmicas permaneceram estáveis durante a intervenção. Os sinais vitais e parâmetros hemodinâmicos permaneceram estáveis durante as duas intervenções. CONCLUSÃO: Nosso relato descreve o uso da raquianestesia contínua com monitoração hemodinâmica minimamente invasiva como uma alternativa válida para a anestesia geral ou peridural em duas pacientes com estenose aórtica grave, submetidas à cirurgia de membro inferior. Contudo, ensaios clínicos controlados são necessários para estabelecer que a técnica é segura e eficaz nesse tipo de pacientes.
