Coping with airway emergencies: Get, Set, Go!

Airway emergencies are among the life-threatening events that are encountered in the operating room, emergency department or intensive care unit. They are important causes of preventable morbidity and mortality where time is the essence. It can be extremely challenging to rapidly assess the airway for early diagnosis and perform appropriate interventions simultaneously. Outcome depends on the implementation of an optimal strategy to establish a patent airway. Equally important is the overall stabilisation of the patient and management of the primary clinical condition as appropriate. Key components of management include early recognition of threatened airway, appropriate and timely airway intervention, and maintaining oxygenation. In this review, we describe aetiology, evaluation and management of airway emergencies.

Palliative Care for Patients with Nonmalignant Respiratory Disease

Nonmalignant respiratory diseases are chronic and life-limiting conditions that need holistic palliative care. Such patients not only have a variety of physical symptoms such as dyspnea, pain, cough, depression, and anxiety, but also have a number of psychosocial and spiritual issues, which are not addressed to by us. This leads to a poor quality of life. Hence, these patients require supportive palliative care to relieve their sufferings, but unfortunately such care is not available to them in our country. In this article, we have tried to discuss the barriers to the provision of palliative care to such patients and suggested some measures to overcome them.

Comparative evaluation of forced air warming and infusion of amino acid-enriched solution on intraoperative hypothermia in patients undergoing head and neck cancer surgeries: A prospective randomised study

BACKGROUND

Inadvertent core hypothermia is a common occurrence during general anaesthesia. Forced air warming (FAW) is the most effective perianaesthetic warming system, but it may lead to thermal discomfort. Amino acids (AAs) have been used to prevent hypothermia, but no study has compared the effect of AA infusion with FAW systems. We have conducted this study to compare the effects of external heating (FAW system) and internal heat generation (AA infusion) in preventing hypothermia during anaesthesia.

METHODS

After institutional review board approval, 80 American Society of Anesthesiologists Grade I/II adult patients admitted for head and neck cancer surgeries lasting more than 2 h under general anaesthesia were included. The patients were randomly divided into two groups using computer-generated codes to receive AA infusion at 3 mL/kg/h, Group AA (N = 40), or normal saline at 3 mL/kg/h with FAW, Group FA (N = 40) till the end of surgery. Standard anaesthetic technique and monitoring was used in all the patients.

RESULTS

The baseline mean temperature in both the groups was comparable. The core temperature was similar in the two groups at 30 min (35.6 ± 0.54 vs 35.5 ± 0.54), 60 min (35.5 ± 0.63 vs 35.3 ± 0.60), 90 min (35.5 ± 0.79 vs 35.2 ± 0.66), 120 min (35.6 ± 0.93 vs 35.2 ± 0.78), 150 min (35.7 ± 0.88 vs 35.3 ± 0.89) and 180 min (35.8 ± 1.01 vs 35.3 ± 0.95) in Groups FA and AA, respectively (P > 0.05). However, the core temperature was significantly higher in Group FA at 210 min (35.8 ± 1.0 vs 35.3 ± 0.85; P = 0.01), 240 min (35.9 ± 1.0 vs 35.4 ± 0.90; (P = 0.001), 270 min (35.9 ± 1.12 vs 35.6 ± 0.97; P = 0.002) and 300 min (36.0 ± 1.12 vs 35.6 ± 1.02; P = 0.002), respectively. Clinically relevant hypothermia (at least one measurement <35.5°C) was comparable between the two groups.

CONCLUSION

The AA infusion can be used as an alternative to FAW in preventing intraoperative hypothermia under general anaesthesia especially in places where FAW system is unavailable.

Effect of Palliative Bronchoscopic Interventions on Symptom Burden in Patients with Central Airway Narrowing: A Retrospective Review

INTRODUCTION

Early integration of palliative interventions in patients with central airway obstruction (CAO) has shown to reduce patients' distress due to breathlessness and achieve better outcomes at lower cost. This retrospective review was performed to determine whether rigid bronchoscopic interventions alleviated the symptom burden and the requirement for continued mechanical ventilation in patients with CAO in a tertiary care hospital.

MATERIALS AND METHODS

Detailed records of 105 patients with CAO were retrospectively studied. The Numerical Rating Scale (NRS) score for cough and dyspnea before and after the intervention was noted. A need for an escalation or reduction in level of care was also noted.

RESULTS

The mean NRS score for dyspnea (n = 84) reduced from 7.5 (4-9) (before procedure) to 2.5 (2-6) after intervention (P < 0.01). The mean NRS score for cough (n = 68) also reduced from 6.5 (4-8) (before procedure) to 4 (3-7) after intervention (P < 0.01). Of these patients, bronchoscopic intervention allowed transfer out of the ICU in 14 patients (42%) and immediate withdrawal of mechanical ventilation in 8 patients (42%).

CONCLUSION

There is an instantaneous valuable palliation of symptoms and improved health-care utilization with airway tumor debulking and stenting. Multidisciplinary interventions with emphasis delivery of palliative care provide better care of patients with CAO.

Initial Perceptions about Palliative Care in Patients with Advanced Cancer: A Prospective Cross-Sectional Audit

INTRODUCTION

There is enough evidence to suggest that early introduction to palliative care (PC) for patients with advanced cancer is beneficial. However, despite this, the patients often come late to PC physicians. There are a number of studies examining the preferences and practices of the physicians with respect to PC. However, there is limited literature exploring the patients' preferences and awareness regarding the PC services. This audit was done to identify the understanding and perceptions of PC in patients visiting PC outpatient department (OPD) and identify strategies to enhance their understanding.

MATERIALS AND METHODS

This prospective cross-sectional study was conducted in 200 advanced cancer patients visiting PC OPD in a tertiary care hospital. The patients were asked to fill a questionnaire to assess their knowledge and expectations form PC on their first visit.

RESULTS

Majority of the patients were from nearby areas and around 20% of them had to travel more than 300 km to receive palliative consultation. Unfortunately, majority of the patients had not heard the term PC before and were not aware of its meaning. Most of them (90%) were send to control pain which was too severe to be managed by the oncologists. We think that the major reason for the lack of awareness about PC services is limited availability across the country and lack of coordinated approach.

CONCLUSIONS

The main problem identified in the audit was the inadequate information, lack of PC setups, and late referral of the patients to PC. Hence, we should make a model where PC services are integrated with the curative services and offered throughout the illness after cancer diagnosis.

Anaesthetic considerations for whole lung lavage for pulmonary alveolar proteinosis

Pulmonary alveolar proteinosis (PAP) is an uncommon lung disease characterized by excessive accumulation of pulmonary surfactant that usually requires treatment with whole-lung lavage. A 47-year-old female presented with history of dry cough and breathlessness for past 6months. Chest radiograph demonstrated bilateral alveolar shadows and high resolution computerized tomography thorax showed crazy paving pattern. Broncho-alveolar lavage (BAL) and transbronchial lung biopsy confirmed a diagnosis of PAP. Due to worsening hypoxemia and respiratory failure, wholelung lavage was planned and performed. Anaesthetic management involved integrated use of pre-oxygenation, complete lung isolation, one-lung ventilation with optimal positive end-expiratory pressure, vigilant use of positional manoeuvres, and use of recruitment manoeuvres for the lavaged lung. We have discussed valuable strategies for the anaesthetic management of patients undergoing this multifaceted procedure in a case of severe PAP.

Failed videolaryngoscopy in an infant with giant vallecular cyst managed successfully with a 'three-person technique' of fibre-optic intubation

Vallecular cysts are a rare entity but can complicate the airway management due to the physical impediment and distortion of the laryngeal inlet. It can lead to fatal life-threatening airway obstruction postinduction of anaesthesia. Infancy compounds the risks due to lack of cooperation and physiological reserves. The literature review suggested most anaesthesiologists avoided muscle relaxants and aspiration of the cyst was used as a rescue technique. The present case report illustrates the successful airway management of an infant with a huge vallecular cyst using fibre-optic intubation by a 'three-person' technique after paraglossal videolaryngoscopy failed to secure the airway.

Airway management of the cardiac surgical patients: Current perspective

The difficult airway (DA) is a common problem encountered in patients undergoing cardiac surgery. However, the challenge is not only just establishment of airway but also maintaining a definitive airway for the safe conduct of cardiopulmonary bypass from initiation to weaning after surgical correction or palliation, de-airing of cardiac chambers. This review describes the management of the DA in a cardiac theater environment. The primary aims are recognition of DA both anatomical and physiological, necessary preparations for (and management of) difficult intubation and extubation. All patients undergoing cardiac surgery should initially be considered as having potentially DA as many of them have poor physiologic reserve. Making the cardiac surgical theater environment conducive to DA management is as essential as it is to deal with low cardiac output syndrome or acute heart failure. Tube obstruction and/or displacement should be suspected in case of a new onset ventilation problem, especially in the recovery unit. Cardiac anesthesiologists are often challenged with DA while inducing general endotracheal anesthesia. They ought to be familiar with the DA algorithms and possess skill for using the latest airway adjuncts.

Safety of anesthetic exposure on the developing brain - Do we have the answer yet?

During the past two decades, a vast number of studies done on rodents and nonhuman primates have implicated general anesthetic exposure of developing brains in producing neurotoxicity leading to various structural and functional neurological abnormalities with cognitive and behavioral deficits later in life. However, it is still unclear whether these findings translate to children and whether single exposure to anesthesia in childhood can have long-term neuro-developmental risks. Considering the fact that a large number of healthy young children are undergoing elective surgery under general anesthesia globally, any such potential neurocognitive risk of pediatric anesthesia is a serious public health issue and is therefore important to understand. This review aims to assess the current preclinical and clinical evidence related to anesthetic neurotoxicity.

Lumbar Erector Spine Plane Block for Pain Management in Postherpetic Neuralgia in a Patient with Chronic Lymphocytic Leukemia

Postherpetic neuralgia (PHN) refers to the chronic neuropathic pain that persists beyond the initial varicella-zoster rash. Patients with chronic lymphocytic leukemia (CLL) are susceptible to infections because of decreased immunity. Various treatment strategies including pharmacological, nonpharmacological, and interventional techniques have been described in the literature. We report the successful management of PHN with lumbar erector spinae plane block in a patient of CLL.

Need for Palliative Care in Patient with Rheumatoid Arthritis: A Cross-sectional Observational Study

OBJECTIVES

Rheumatoid arthritis (RA) is a chronic disorder causing inflammation in the joints and achieving remission is often the primary goal of physicians. We evaluated the suffering from RA and assessed the need for palliative care services in these patients.

MATERIALS AND METHODS

This cross-sectional observational study was done in 100 adult RA cases who attended the outpatient department. The Disease Activity Score 28 (DAS28), Health Assessment Questionnaire Disability Index, depression, anxiety and stress score, Short Form 36 Health Survey and numeric rating scale were assessed. The relationship between DAS28 with the other parameters and scores was assessed using Spearman's rho correlation coefficient.

RESULTS

About 90% of patients in our study were female and majority (50%) had a moderate disease activity. The DAS28 showed a positive correlation with the degree of depression (r = 0.671, P = 0.000), anxiety (r = 0.609, P = 0.000) and stress levels (r = 0.474, P = 0.000). The patients with severe disease had a poor quality of life (QoL) [physical functioning (r = -0.737, P = 0.000); role limitation (r = -0.662, P = 0.000); emotional problem (r = -0.676, P = 0.000); energy/fatigue (r = -0.638, P = 0.000); social functioning (r = -0.658, P = 0.000); emotional well-being (r = -0.605, P = 0.000); general health (r = -0.643, P = 0.000); health change (r = -0.376, P = 0.000) and numerical rating scale score for pain (r = 0.656, P = 0.000)].

CONCLUSION

RA patients with high disease activity suffer from depression, anxiety, stress and poor QoL. Palliative care physicians and rheumatologists must be vested with the power to provide comprehensive care to these patients.

Total control introducer-aided nasotracheal intubation using a videolaryngoscope in an anticipated difficult airway: a novel technique

Nasotracheal intubation can be challenging due to undesirable incidence of nasal bleeding and soft tissue injuries. The bleeding can obscure glottis visualisation, increase the total intubation time, the risk of aspiration and oxygen desaturation. Total control introducer is a new airway adjunct with a flexible shaft, articulating tip and an intuitive depth control system, which can be used in difficult airway scenarios to improve the success of nasal intubations.

Iatrogenic Complete Ventilatory Failure in Two Neonates Undergoing Tracheoesophageal Fistula Repair

Tracheoesophageal fistula (TEF) is one of the most common congenital anomalies presenting for emergency surgical correction in a neonate. The surgical approach is through the right thoracotomy in the lateral decubitus position. The pathology and surgical approach complicate the ventilatory management for this subset of neonates. Several possible causes of ventilatory insufficiency have been reported during the surgical repair in these cases. We report unusual causes of complete ventilatory failure in two patients undergoing TEF repair.

El-Ganzouri multivariate risk index based airway management in head and neck cancer patients: A retrospective analysis of 1000 patients in a tertiary care center

BACKGROUND AND AIMS

Intubation in head and neck carcinoma (HNC) is difficult due to many reasons. Various guidelines recommend strategies for airway management in such anticipated difficult airway cases. However, literature is limited on airway management planning as per the level of difficulty based on airway assessment in these patients. EL-Ganzouri risk index (EGRI) has been proposed to aid in making airway management plan in HNC cases by some authors. This retrospective study was conducted to look at the data related to the pre-anesthetic airway assessment and the airway management plan executed by the anesthesiologists in 1000 patients of HNC in the previous nearly four years in order to determine how the choices made conformed to EGRI scores.

MATERIAL AND METHODS

Records of all the patients with oral cancer posted for surgery over four years from January 2014 to December 2017 were retrospectively analyzed for preoperative airway assessment using El Ganzouri risk index assessment (EGRI), the intraoperative technique for nasotracheal intubation, airway management plan, and any intraoperative complications.

RESULTS

The risk of predicted airway difficulty was low (EGRI <4) in 38 patients and was high in the rest. The EGRI score was higher in the FOB group [4-9] as compared to DL [2-3] and VL [1-6]. The patients with EGRI >7 were intubated awake and those with EGRI <7 were intubated under general anesthesia (79.8%). Overall, the technique of choice for intubation was fibreoptic bronchoscopy (54%) followed by video laryngoscopy (42.6%).

CONCLUSION

The airway management plan used in a tertiary care cancer center conformed to the approach suggested by the multivariate El Ganzouri risk index (EGRI). EGRI appears to be a useful means to ascertain the appropriate strategies for intubation in head and neck cancer patients.

Effect of Opioid-Free General Anesthesia Versus Opioid-Based General Anesthesia on Postoperative Pain and Immune Response in Patients Undergoing Breast Cancer Surgery: A Randomized Controlled Trial

Perioperative opioids are associated with several adverse effects including nausea, vomiting, and long-term addiction. Opioid-free anesthesia may reduce postoperative morbidity, enable daycare surgery, and decrease cancer recurrence. In our study, we aimed to assess the efficacy of opioid-free anesthesia versus opioid-based anesthesia in patients undergoing breast cancer surgery in terms of postoperative opioid use, pain scores, expression of immune cells, and side effects. Hundred patients undergoing breast cancer surgery were randomized into two groups (1:1 ratio). Group O received opioid-based anesthesia and Group N did not receive any opioid intraoperatively. Our primary outcome was total postoperative morphine consumption in 24 h managed with a patient-controlled analgesia (PCA) pump containing morphine in both groups. Secondary outcomes were numerical rating scale (NRS) at rest and movement at immediate postoperative period, 30 min, 1 h, 2 h, 6 h, and 24 h postoperatively was measured. Blood samples were also taken at different time points to measure inflammatory markers. There was no statistical difference in the total 24 h postoperative morphine consumption in between the two groups (p = 0.13). The patient satisfaction scores and NRS at rest and on movement at various time points postoperatively were similar (p > 0.05). There was a significant difference in neutrophil lymphocyte ratio (NLR) between the two groups in the samples taken at 24 h postoperative period (p = 0.03). No complications were reported in any group. While our study did not show opioid-free anesthesia's superiority in postoperative morphine consumption, it established the feasibility and safety of a non-opioid technique for breast cancer surgery. The approach may offer advantages, including potential immunosuppression relief, making it a viable option for patients prone to opioid-related side effects.

Erector spinae plane block using clonidine as an adjuvant for excision of chest wall tumor in a pediatric patient

Erector spinae plane block has been described to manage post-thoracotomy pain. It is a simple block and shown to be provide effective analgesia. In single shot blocks opioid supplementation may be required to manage pain after the effect of local anesthetic wears off. In this case, we describe a case of chest wall tumor excision in a child who received clonidine in addition to local anesthetic for the erector spinae plane block. This provided long lasting and effective postoperative analgesia and may be considered to prolong the analgesia achieved with erector spinae plane block.
