ObjectivesBowel dysfunction is a major complication following open surgery for invasive cancer of the bladder that results in significant discomfort; complications and can prolong the length of stay. The incidence of postoperative ileus following open radical cystectomy has been reported as 23–40%. The median length of hospital stay after this surgery in the United Kingdom is 11 days. Standard analgesic techniques include wound infusion analgesia combined with systemic morphine or thoracic epidural analgsia. Combined erector spinae plane and intrathecal opioid analgesia is a novel technique that has been reported to be an effective method of providing perioperative analgesia thereby enhancing recovery after open radical cystectomy.MethodsWe performed a prospective study on the effectiveness of the novel analgesic technique (combined erector spinae plane and intrathecal opioid analgesia) in reducing the incidence of postoperative ileus, thereby facilitating early discharge following open radical cystectomy when compared to a contemporaneous control group receiving standard analgesia. Twenty-five patients received the novel analgesia while 31 patients received standard analgesia as a part of enhanced recovery programme. Standard analgesia arm included 14 patients who recived thoracic epidural analgesia (14/31, 45%) and 17 patients who received combined wound infusion analgesia and patient controlled analgesia with morphine (17/31, 55%). Primary outcome was the incidence of postoperative ileus. Secondary outcomes included length of hospital stay, tramadol consumption and time to bowel opening.ResultsCombined erector spinae plane and intrathecal opioid analgesia was associated with a reduced incidence of postoperative ileus (16 [4/25] vs. 65% [20/31], p<0.001), reduced time to first open bowel (4.4 ± 2.3 vs. 6.6 ± 2.3, p<0.001) and reduced median (IQR) length of hospital stay (7[6, 12] vs. 10[8, 15], p=0.007). There was no significant difference in rescue analgesia (intravenous tramadol) consumption. Complete avoidance of systemic morphine played a key role in improved outcomes.ConclusionsESPITO was successful in reducing postoperative ileus and length of hospital stay after open radical cystectomy when compared to standard analgesia within an enhanced recovery programme.
COVID-19 has been declared a pandemic since March 2020 and it has been responsible for millions of deaths worldwide. The SARS-CoV-2 causes a spectrum of diseases mainly affecting the respiratory system. It can also complicate other systems causing thromboembolic phenomena and myocardial ischaemia. An entity of hypoxia has been described in these patients which show no clinical signs and symptoms of respiratory distress despite being extremely hypoxic. This is called silent or happy hypoxia. The exact mechanism for this is not known. We report 4 cases which had similar presentations of silent hypoxia but had different course of illness and different outcomes. All 4 patients did not show any signs of respiratory distress, but had oxygen saturation less than 82%. 3 of them needed intensive care unit support for oxygen therapy and subsequently needed noninvasive ventilation. Only one required invasive ventilation. The fourth patient did not require intensive care support. The patient who required invasive ventilation succumbed due to severe COVID pneumonia whereas the other 3 patients were discharged from the hospital. Silent hypoxemia can go undetected in COVID-19 patients particularly in the time of a pandemic. This case series highlights the importance of meticulous clinical examination including oxygen saturation measurements in suspected or confirmed patients with COVID-19. The course of illness can be different in different populations, and this needs further clinical evidence.
BackgroundThe adult population in Sri Lanka is having high level of susceptibility for Varicella Zoster Virus (VZV) infection. Among medical undergraduates, 47% are VZV seronegative. The purpose of the present study was to determine the incidence of VZV infection in medical undergraduates in Sri Lanka, and to describe the effects of VZV infection on their academic activities.MethodsA retrospective cohort of medical undergraduates' susceptible for VZV infection was selected from the University of Peradeniya, Sri Lanka. Data on the incidence of VZV infection (Chickenpox) during their undergraduate period was collected using a self-administered structured questionnaire. A second questionnaire was administered to collect data on the details of VZV infection and the impact of it on their academic activities. VZV incidence rate was calculated as the number of infections per 1,000 person years of exposure. Descriptive statistics were used to describe the impact of VZV infection on academic activities.ResultsOut of the 172 susceptible cohort, 153 medical undergraduates were followed up. 47 students reported VZV infection during the follow up period and 43 of them participated in the study. The cumulative incidence of VZV infection during the period of five and half years of medical training was 30.7%. Incidence density of VZV infection among medical undergraduates in this cohort was 65.1 per 1,000 person years of follow-up. A total of 377 working days were lost by 43 students due to the VZV infection, averaging 8.8 days per undergraduate. Total academic losses for the study cohort were; 205 lectures, 17 practicals, 13 dissection sessions, 11 tutorials, 124 days of clinical training and 107 days of professorial clinical appointments. According to their perception they lost 1,927 study hours due to the illness (Median 50 hours per undergraduate).ConclusionsThe incidence of VZV infection among Sri Lankan medical undergraduates is very high and the impact of this infection on academic activities causes severe disruption of their undergraduate life. VZV immunization for susceptible new entrant medical undergraduates is recommended.
Difficult airway is a common problem encountered in oro-maxillo-facial surgeries. We describe a case where a displaced mandibular reconstruction plate obstructing the access to oral cavity. The airway was further compromised by previous tracheostomy, and limited neck extension owing to previous surgeries and radiotherapy. The inability of the patient to swallow increased the risk of pulmonary aspiration. The first line of airway management in such patient should be fibro-optic laryngoscopy. However, one must have alternative plans for securing airway if there are expected difficulties with fiberoptic laryngoscopy. Such plans were made considering her clinical presentation. We believe this case highlights the importance of pre-planning the strategies for airway management according to the presentation.
