RESUMEN
BACKGROUND: Existing literature lacks high-quality evidence regarding the ideal intraoperative positive end-expiratory pressure (PEEP) to minimize postoperative pulmonary complications (PPCs). We hypothesized that applying individualized PEEP derived from electrical impedance tomography would reduce the severity of postoperative lung aeration loss, deterioration in oxygenation, and PPC incidence. METHODS: A pilot feasibility study was conducted on 36 patients who underwent open abdominal oncologic surgery. The patients were randomized to receive individualized PEEP or conventional PEEP at 4 cmH2O. The primary outcome was the impact of individualized PEEP on changes in the modified lung ultrasound score (MLUS) derived from preoperative and postoperative lung ultrasonography. A higher MLUS indicated greater lung aeration loss. The secondary outcomes were the PaO2/FiO2 ratio and PPC incidence. RESULTS: A significant increase in the postoperative MLUS (12.0 ± 3.6 vs 7.9 ± 2.1, P < 0.001) and a significant difference between the postoperative and preoperative MLUS values (7.0 ± 3.3 vs 3.0 ± 1.6, P < 0.001) were found in the conventional PEEP group, indicating increased lung aeration loss. In the conventional PEEP group, the intraoperative PaO2/FiO2 ratios were significantly lower but not the postoperative ratios. The PPC incidence was not significantly different between the groups. Post-hoc analysis showed the increase in lung aeration loss and deterioration of intraoperative oxygenation correlated with the deviation from the individualized PEEP. CONCLUSIONS: Individualized PEEP appears to protect against lung aeration loss and intraoperative oxygenation deterioration. The advantage was greater in patients whose individualized PEEP deviated more from the conventional PEEP.

Foreign body (FB) aspiration is a potentially life-threatening accident in children. Traditionally, rigid bronchoscopy has been the procedure of choice for FB removal, however it may miss distally lodged FBs. We report two pediatric cases with distal impacted FBs that could not be retrieved by rigid bronchoscopy (RB) and were mobilised using Fogarty balloon followed by flexible bronchoscopic cryoextraction. The advantage of a cryoprobe is lower risk of fragmentation of FB that may occur with forceps. Cryoextraction is particularly advantageous for removing water-containing FBs. In both patients, FB was removed more than 2 weeks following aspiration, leading to the formation of granulation tissue around the FB, which considerably hampered the process. Using a laryngeal mask airway to secure the airway, FB removal by flexible bronchoscopy may be a safe and effective technique in skilled hands, especially for FBs impacted in distal airways with granulation tissue where RB fails.

India has a high share in the global burden of chronic terminal illnesses. However, there is a lack of a uniform system in providing better end-of-life care (EOLC) for large patients in their terminal stage of life. Institutional policies can be a good alternative as there is no national level policy for EOLC. This article describes the important aspects of the EOLC policy at one of the tertiary care institutes of India. A 15 member institutional committee including representatives from various departments was formed to develop this institutional policy. This policy document is aimed at helping to recognize the potentially non-beneficial or harmful treatments and provide transparency and accountability of the process of limitation of treatment through proper documentation that closely reflects the Indian legal viewpoint on this matter. Four steps are proposed in this direction: (i) recognition of a potentially non-beneficial or harmful treatment by the physicians, (ii) consensus among all the caregivers on a potentially non-beneficial or harmful treatment and initiation of the best supportive care pathway, (iii) initiation of EOLC pathways, and (iv) symptom management and ongoing supportive care till death. The article also focuses on the step-by-step process of formulation of this institutional policy, so that it can work as a blueprint for other institutions of our country to identify the infrastructural needs and resources and to formulate their own policies.

Objective: Awake proning is an intervention that is being advocated for COVID-19 patients and has been suggested to improve the oxygenation, thereby decreasing oxygen requirements. We performed this systematic review with the aim of appraising the latest published evidence on the clinical effectiveness of awake proning in COVID-19 patients. Data sources: PubMed, EMBASE, The Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, Google Scholar, and one trial registry were searched until September 23, 2020, for studies on the use of awake proning for nonintubated COVID-19 patients. Study selection: Published or in-press peer-reviewed randomized control trials, case-control trials, and prospective or retrospective cohort studies in English language only were sought, assessing the effectiveness of awake proning for nonintubated patients diagnosed with COVID-19. Data results: We included 21 published studies (19 single arm and 2 with comparison group). Twenty-three registered clinical trials were identified. No randomized clinical trial has been published so far. Conclusions: Awake proning is probably safe and effective in enhancing oxygenation in nonintubated COVID-19 patients; however, there is insufficient evidence. Further high-quality clinical trials are urgently needed to assess the effectiveness of awake proning on a variety of patient-centered outcomes.

RESUMEN
BACKGROUND: The ongoing coronavirus disease 2019 (COVID-19) pandemic has affected all the aspects of life of mankind, posing unique challenges for health-care services. In order to contain the spread of the virus, a countrywide mass lockdown has been imposed in India. Although the lockdown has modified the epidemic trajectory, it has affected the lives of many non-COVID patients. Patients in need of care could not approach hospitals. METHODS: This retrospective observational study was conducted in the Department of Onco-Anaesthesia and Palliative Medicine at a tertiary care center in India. The yearly data of patient flow for the year 2019 was compared with that during the lockdown. RESULTS: The single-day average of out-patients, in-patients, and other department consultation requests requiring palliative care decreased drastically during the lockdown in comparison to the previous year. The single-day average of teleconsultations increased more than double during the lockdown. CONCLUSION: Although lockdown decreases the spread of the epidemic, it increases the suffering of other patients who require medical care. Various steps have to be adopted in the regular working pattern of hospitals to cater to the needs of the patients requiring care, without increasing the risk of contracting COVID-19.
RESUMEN
Palliative surgery forms an important pillar of palliative treatment to provide holistic care to cancer patients in the form of providing relief from pain, local control of disease, hemorrhage, and for the purpose of rehabilitation. During the COVID-19 pandemic, we report the successful management of two cases of colorectal cancer which came under the category of high priority and underwent palliative surgery to provide relief from pain.
