Non-intubated Patient Research Articles

A glance at the history of uniportal video-assisted thoracic surgery.

In the history of thoracic surgery, the advent of video-assisted thoracic surgery (VATS) had on effect equivalent to that provoked by a true revolution. VATS successfully allowed minor, major and complex procedures for various lung and mediastinal pathologies with small incision instead of the traditional accesses. These small incisions abolished ugly scars, generated less acute and chronic pain, reduced hospital stay and costs, allowed faster return to normal day life activities. Conventional VATS was initially performed through 3-4 ports and rapidly evolved to uniportal or single portal access [uniportal video-assisted thoracic surgery (uniVATS)]. First uniportal procedures were published in 2000. In 2010, uniportal technique for lobectomy was described. Focused experimental courses, live surgery events, the internet media favored the rapid diffusion of this technique over the world. Major and complex uniVATS lung resections involving segmentectomy, pneumonectomy, bronchoplasty and vascular reconstruction, redo VATS, en bloc chest wall resections have been accomplished with satisfactory outcomes. Interestingly, different uniportal approaches and techniques are emerging from a number of VATS centers particularly experienced in the mini-invasive thoracic surgery. As confidence grew, in 2014, the first uniVATS left upper lobectomy via the subxiphoid approach was reported. This novel technique is quite challenging but appropriate patient selection as well as availability of dedicated instruments allowed to perform procedures safely. The diffusion of uniVATS paralleled with the development of nonintubated awake anesthesia technique. In 2007 the first nonintubated lobectomy was described. In 2014 the first single port VATS lobectomy in a nonintubated patient with lung cancer of the right middle lobe was accomplished. The nonintubated uniVATS represents an intriguing technique, so that very experienced thoracoscopic surgeons may enroll to surgery elderly and high risk patients. Decreased postoperative pain and hospitalization, faster access to the radio-chemotherapy and diminished inflammatory response are important benefits of the modern approach to the thoracic pathologies. The history of uniVATS documented a constant and irresistible progress. This technique may further provide unthinkable surprises in next future.

Evaluating the Effectiveness of End-Tidal Carbon Dioxide Monitoring During Burn Wound Care in the Nonintubated Patient Population

Daily burn wound care for nonintubated patients involves administration of intravenous analgesic and sedation agents. Vital signs and oxygen saturation monitoring alone can result in late signs of oversedation and ineffective breathing. End-tidal carbon dioxide (EtCo2) monitoring provides immediate feedback of effective breathing during procedural sedation. The purpose of this study was to describe the nurse's sedation and analgesic therapy management of nonintubated patients during burn wound care when EtCo2 was used. This IRB approved study involved observing 22 burn nurses and 4 burn technicians during burn wound care of nonintubated patients. This descriptive, observational study compared adverse breathing/airway events, pain measurements, and sedation effectiveness, before and after introducing EtCo2 monitoring. Patients observed in this study were similar in age, type and size of burn, and use of recreational substances. Nurses and technicians also had similar burn experience. No statistically significant findings were found in this study; however, nurses in practice longer were found to apply oxygen sooner, which prevented decreased oxygen saturation events. When EtCo2 was used, less analgesia and sedation were required to maintain patient comfort. Time required for burn wound care was reduced by 22%, and 30% less overall analgesic and sedation agent dosages were administered after the introduction of EtCo2 monitoring. EtCo2 was found to enhance nurses' assessment of patients' response to intravenous analgesia and sedation effectiveness during burn wound care for nonintubated patients. Nurses with greater experience used oxygen sooner in the procedure, and patients had fewer decreases in SpO2.

Medical thoracoscopy in China-the present status and the future.

Medical thoracoscopy (MT) refers to a minimally invasive procedure to inspect and perform a biopsy of the pleural space, as well as to perform therapeutic interventions, in a nonintubated patient under local anesthesia. This procedure provides the physician a window into the pleural space. Over the past two decades, MT has been developed very rapidly in China. We performed a review of the published data on MT in China, and estimated the present status, the challenges, and future perspectives of MT. From the data we conduct that MT is widely used well in China, not only in the diagnosis of exudative pleural effusions, but also in the management of pleural diseases, such as tuberculous pleural effusion, malignant pleural effusion and spontaneous pneumothorax. Meanwhile, it is noteworthy that few prospective clinical trials, lack of routine follow-up of MT are current domestic problems for diagnosis and management in pleural effusion. Consequently, more prospective, randomized clinical trials are needed to assess the diagnostic value and treatment superiorities of MT compared with traditional methods or other subjects in China in the future.

First non-intubated uniportal video-assisted pulmonary lobectomy in America.

The first video-assisted thoracic lobectomy in non-intubated patient in America was performed on 27th of September 2014 in Bogotá Colombia, The National Cancer Institute in Bogotá received Dr. Diego González-Rivas to make possible this kind of procedure in a 53-year-old man, with a history of papillary thyroid cancer treated with surgery and Iodine therapy, in whom two pulmonary nodules were found in the monitoring tomography. We resected the nodule located at the right upper lobe previously marked by scintigraphy, the other one required a lobectomy because it was a deep nodule with malignant radiologic appearance inside of the middle lobe. The procedure discoursed in a non-intubated patient without technical difficulties or complications, very short recovery time, minimum pain and a quiet and usual postoperative evolution. This procedure, the first reported in America was replicated after others with similar results in several countries thanks to the collaboration between surgeons, anesthesiologists, radiologists, nurses and therapists, because especially in such interventions teamwork is essential. We believe that given the benefits in terms of recovery for the patient and anesthetic time, we could go on replicating the experience in selected patients.

Clinical Evaluation of Comprehensive Versus Routine Oral Care among Critically Ill Patients

Oral care is an essential nursing management for critically ill patients who cannot carryout his activity by themselves in critical care units. Oral care of the critically ill affect theincidence of periodontal illness. The study aimed to evaluate the effect of comprehensive versusroutine oral care on oral health of critically ill patients at intensive care unit. To achieve this aim, a quasiexperimentalresearch design was utilized. The study was carried out at the Intensive Care Unit at TantaEmergency Hospital. A convenient sample of 40 adult patients were selected and randomly divided intotwo equal groups, 20 patients in each group. Two tools were used for data collection. Tool I: Critically IllPatient’s Assessment Sheet and Tool II: Oral Assessment guide Scale. Hypotheses: The comprehensiveoral care is more effective than routine oral care in minimizing oral problems for critically ill patients atintensive care unit. The results showed that there was no significance difference between study andcontrol group in the first day of admission. However at third and seventh day of admission, there wassignificant improvement of condition of swallow, lips, tongue, mucus membrane, teeth, and Oder in studygroup compared to control group. While the difference was significant on seven day only in gingival andsaliva with P = 0.00. The study concluded that oral comprehensive care was more effective than oralroutine care in improving oral health status of critically ill patients. Based on findings of the study it isrecommended to use comprehensive oral care for ICU patients as well as the non-intubated patient withself-care deficits. Assessment of oral health status should be incorporated as part of routine care ofcritically ill patients.

Video-assisted transthoracic surgery resection of a tracheal mass and reconstruction of trachea under non-intubated anesthesia with spontaneous breathing.

Radical surgery for tracheal tumors is typically completed under basal anesthesia. Thus, endotracheal intubation and mechanical ventilation are required. However, these procedures may influence the surgical operation and meanwhile prolong the surgical duration and postoperative recovery. In this article we describe the application of video-assisted transthoracic surgery (VATS) resection of a tracheal mass and reconstruction of trachea a non-intubated patient with spontaneous breathing.

Nonintubated uniportal video-assisted thoracic surgery course-live surgery.

"Uniportal video-assisted thoracic surgery (VATS) course-live surgery" was held on 23rd of November 2015 in Lithuania, The Hospital of Lithuanian University of Health Sciences Kaunas Clinics. This international event has attracted many thoracic surgeons, doctors anesthesiologists-reanimatologists, operative theatre nurses and other medical specialists from Lithuania, Latvia, Estonia and Poland. The special guests of the conference were thoracic surgeon Dr. Diego Gonzalez-Rivas and doctor anesthesiologist Dr. Humberto Aymerich Cano. Since the first uniportal VATS lobectomy was performed on 29th of July, 2010, this innovative minimally invasive surgical technique has been adopted in many countries of the world. The first nonintubated VATS for lobectomy was initially described in 2007, although general anesthesia with intubation and one lung ventilation was traditionally considered to be necessary for major thoracoscopic pulmonary resections. During this course, right upper and left upper uniportal VATS lobectomies were performed for nonintubated patients, diagnosed with non-small cell lung cancer. These successful examples demonstrate a minimally invasive surgical technique-uniportal VATS lobectomy for a nonintubated patient.

Management of the Interventional Stroke Patient.

The acute treatment of major ischemic stroke has been revolutionized by strong and consistent evidence from multiple randomized trials. Endovascular treatment by mechanical thrombectomy will be increasingly chosen as an adjunctive or alternative to intravenous thrombolysis. To apply this form of stroke treatment is associated with the challenge of optimal periinterventional treatment. The patient has to be identified, counselled, prepared, monitored, cardiovascularly stabilized, possibly sedated and ventilated, and postprocedurally treated in the optimal way. However, most aspects of periinterventional treatment have as yet not been clarified and require prospective research. Among these, the question of general anesthesia vs conscious sedation has received most attention and may be the most crucial one. Based on a great amount of retrospective data, it appears reasonable to start the intervention under conscious sedation of the non-intubated patient with standby measures for emergent intubation, until prospective randomized trials have clarified that issue. Periinterventional management will significantly affect the success of recanalization.

Uniportal video-assisted thoracoscopic left upper lobectomy under spontaneous ventilation.

Intubated general anesthesia with one-lung ventilation was traditionally considered necessary for thoracoscopic major pulmonary resections. However, non-intubated thoracoscopic lobectomy can be performed by using conventional and uniportal video-assisted thoracoscopic surgery (VATS). These non-intubated procedures try to minimize the adverse effects of tracheal intubation and general anesthesia but these procedures must only be performed by experienced anesthesiologists and skilled thoracoscopic surgeons. Here we present a video of a uniportal VATS left upper lobectomy in a non-intubated patient, maintaining the spontaneous ventilation.

First Berlin Heart EXCOR Pediatric VAD Interhospital Transports of Nonambulatory Patients with the Ikus Stationary Driver

Ventricular assist devices (VADs) are increasingly being used in pediatric patients to support cardiac failure. As more centers adopt this technology, there may be a need to transport these patients over long distances to facilitate patient care and organ transplantation. Food and Drug Administration indications for use state only that the patient must be a candidate for transplantation and does not place restrictions on the transplant capabilities of the implanting medical center. Nontransplanting institutions are able to use this technology with a predetermined agreement to transfer the patient to a partnering transplant center. We report the first two cases of interhospital air and ground transport of nonambulatory or intubated pediatric (<13 kg) patients supported by Berlin Heart EXCOR pediatric VADs and Ikus stationary drivers. We present our protocol for transporting this delicate patient population. In addition, we discuss important challenges encountered on these operations regarding vehicle transfers and the management of vehicle power supply. These two cases demonstrate that the transportation of pediatric patients on Berlin Heart VADs is feasible and safe and should be considered a treatment option in certain situations.

Capnography for the Nonintubated Patient in the Emergency Setting

BackgroundMultiple studies illustrate the benefits of waveform capnography in the nonintubated patient. This type of monitoring is routinely used by anesthesia providers to recognize ventilation issues. Its role in the administration of deep sedation is well defined. Prehospital providers embrace the ease and benefit of monitoring capnography. Currently, few community-based emergency physicians utilize capnography with the nonintubated patient. ObjectiveThis article will identify clinical areas where monitoring end-tidal carbon dioxide is beneficial to the emergency provider and patient. DiscussionCapnography provides real-time data to aid in the diagnosis and patient monitoring for patient states beyond procedural sedation and bronchospasm. Capnographic changes provide valuable information in such processes as diabetic ketoacidosis, seizures, pulmonary embolism, and malignant hyperthermia. ConclusionsCapnography is a quick, low-cost method of enhancing patient safety with the potential to improve the clinician's diagnostic power.

Extracorporeal Life Support and Left Ventricular Unloading in a Non-Intubated Patient as Bridge to Heart Transplantation

Veno-arterial extracorporeal life support (ECLS) is a well-established bridging therapy in patients with cardiac or pulmonary failure to maintain organ function and is frequently performed in patients who are not intubated. However, severly impaired cardiac function can occur pulmonary edemy in these patients, necessitating left ventricular unloading. In this study we report a 37-year old female patient with familiar dilated cardiomyopathy suffering from acute biventricular heart failure. After implantation of a peripheral ECLS, the decreased ventricular led to refractory pulmonary edema. To unload the left ventricle, an percutaneous balloon atrioseptostomy was performed without intubating the patient. The left ventricle was vented by the venous cannula resting inside the atrioseptostomy. After twelve days on ECLS, the patient underwent orthotopic heart transplantation. The postoperative course was uneventful and the patient discharged from intensive care unit four days after surgery. In this report we present a patient in which the hybrid technique of ECLS with secondary left ventricular unloading was successfully used as a bridge to transplant therapy. This procedure may offer an alternative bridge-to-decision options in selected patients, including those that were not intubated or anaesthetized.

Extracorporeal membrane oxygenation in a nonintubated patient with acute respiratory distress syndrome

To the Editors: Endotracheal intubation and mechanical ventilation are mainstays in the management of patients with acute respiratory distress syndrome (ARDS), but this treatment strategy exposes the patient to several risks and complications. A small number of ARDS patients can be treated with noninvasive ventilation and these patients have less ventilator-associated pneumonia and a lower mortality rate [1]. However, failure to improve oxygenation with noninvasive ventilation indicates the need for endotracheal intubation [1]. In patients with severe respiratory failure, extracorporeal membrane oxygenation (ECMO) is increasingly being used on top of mechanical ventilation to facilitate oxygenation and protective ventilation [2]. A novel concept is the use of ECMO in awake, spontaneously breathing patients to avoid the complications of invasive ventilation. So far, “awake ECMO” has been used predominantly in patients with end-stage lung disease as bridge to lung transplantation [3, 4]. The use of awake ECMO as …

Double lumen bi-cava cannula for veno-venous extracorporeal membrane oxygenation as bridge to lung transplantation in non-intubated patient

Extracorporeal membrane oxygenation (ECMO) is used for refractory respiratory failure. Normally, ECMO is implanted in intubated patients as a last resort. We report the case of a non-intubated patient who benefited from veno-venous (VV) ECMO. A 35-year old cystic fibrosis man presented a severe respiratory decompensation with refractory hypercapnia. We opted for an ECMO instead of mechanical ventilation (MV). We implanted a double lumen bi-cava cannula (DLC) (Avalon Elite(TM)) in the right jugular vein. Before ECMO implantation, the patient presented refractory respiratory failure (pH = 7.1, PaO(2) = 83 mmHg, PaCO(2 )= 103 mmHg). We proposed that the patient be placed on the high emergency lung transplantation waiting list after failure to wean him from ECMO. This registration was effective 10 days after ECMO implantation. The patient was grafted the next day. Under ECMO, mean PaO(2), PaCO(2) and TCA were 80.6 ± 14.2, 53.8 ± 6.4 mmHg and 56.2 ± 9.7 s, respectively. The patient could eat, drink, talk and practice chest physiotherapy. The evolution was uneventful under ECMO. Weaning from ECMO was done in the operating theatre after transplantation. VV ECMO with DLC is safe and feasible in non-intubated patients. It avoids potential complications of MV, and allows respiratory assistance as bridge to transplantation.

A retrospective analysis of benzodiazepine sedation vs. propofol anaesthesia in 252 patients undergoing endoscopic retrograde cholangiopancreatography

BackgroundHistorically, hepatopancreatobiliary surgeons and gastroenterologists have undertaken endoscopic retrograde cholangiopancreatography (ERCP) using benzodiazepine sedation (BS). This is poorly tolerated by a substantial number of patients, which leads to its potential premature abandonment and subsequent additional investigations and therapeutics, and hence to the exposure of patients to avoidable risk and the health service to increased costs. Furthermore, concerns have been raised in the recent literature regarding safe sedation techniques. ObjectivesThe aim of this study was to compare the completion rates and safety profile of ERCP using BS vs. those of ERCP using light propofol anaesthesia (PA). MethodsWe carried out a retrospective, case-matched comparison analysis of consecutive patients who underwent ERCP with BS vs. PA, in the presence of an anaesthetist, over a 2-year period. Benzodiazepine sedation consisted of midazolam, fentanyl and buscopan. Propofol anaesthesia consisted of propofol, fentanyl and buscopan administered via a mouth guard in a non-intubated patient. Patient demographics, complications and completion rates were recorded. Procedural monitoring included pulse oximetry, non-invasive blood pressure, electrocardiography and end-tidal CO2. Statistical analyses used t-tests to compare continuous variables and chi-squared and Fisher's exact tests to compare categorical variables. A P-value of <0.05 was considered significant. ResultsOf 252 patients included in the study, 128 (50.8%) received BS and 124 (49.2%) received PA. Median ages in the BS and PA groups were 69 years (range: 20–99 years) and 65 years (range: 26–98 years), respectively (P= 0.07). Median hospital stays in the BS and PA groups were 1 day (range: day case to 61 days) and 1 day (range: day case to 38 days), respectively (P= 0.61). Incidences of mild anaesthesia-related complications in the BS and PA groups were 2.3% and 2.4%, respectively (P= 0.97). There were no severe anaesthesia-related complications. Incidences of mild procedural complications in the BS and PA groups were 2.3% and 1.6%, respectively (P= 0.68). One severe procedural complication occurred in the PA group. Incidences of incomplete ERCP procedures in the BS and PA groups were 10.9% (n= 14) and 4.0% (n= 5), respectively (odds ratio = 2.92, 95% confidence interval 1.02–8.38; chi-squared test, P= 0.04; Fisher's exact test, P= 0.03). ConclusionsPropofol anaesthesia for ERCP carried out in the presence of an anaesthetist is safe and may improve procedural completion rates.

Dexmedetomidine Controls Agitation and Facilitates Reliable, Serial Neurological Examinations in a Non-Intubated Patient with Traumatic Brain Injury

We report the effective use of dexmedetomidine in the treatment of a patient with a history of chronic alcohol abuse and an acute traumatic brain injury who developed agitation that was unresolved if from traumatic brain injury, or alcohol withdrawal or the combination of both. Treatment with benzodiazepines failed; lorazepam therapy obscured our ability to do reliable neurological testing to follow his brain injury and nearly resulted in intubation of the patient secondary to respiratory suppression. Upon admission to hospital, the patient was first treated with intermittent, prophylactic doses of lorazepam for potential alcohol withdrawal based upon our institution's standard of care. His neurological examinations including a motor score of 6 (obeying commands) on his Glasgow Coma Scale testing, laboratory studies, and repeat CT head imaging remained stable. For lack of published literature in diagnosing symptoms of patients with a history of both alcohol withdrawal and traumatic brain injury, a diagnosis of agitation secondary to presumed alcohol withdrawal was made when the patient developed acute onset of tachycardia, confusion, and extreme anxiety with tremor and attempts to climb out of bed requiring him to be restrained. Additional lorazepam doses were administered following a hospital-approved protocol for titration of benzodiazepine therapy for alcohol withdrawal. The patient's mental status and respiratory function deteriorated with the frequent lorazepam dosing needed to control his agitation. Dexmedetomidine IV infusion at a rate of 0.5 mcg/kg/h was then administered and was titrated ultimately to 1.5 mcg/kg/h. After 8 days of therapy with dexmedetomidine, the patient was transferred from the ICU to a step-down unit with an intact neurological examination and no evidence of alcohol withdrawal. Airway intubation was avoided during the patient's entire hospitalization. This case report highlights the intricate balance between the side effects of benzodiazepine sedation for treatment of agitation and the difficulties of monitoring the neurological status of non-intubated patients with traumatic brain injury. Given the large numbers of alcohol-dependent patients who suffer a traumatic brain injury and subsequently develop agitation and alcohol withdrawal in hospital, dexmedetomidine offers a novel strategy to facilitate sedation without neurological or respiratory depression. As this case report demonstrates, dexmedetomidine is an emerging treatment option for agitation in patients who require reliable, serial neurological testing to monitor the course of their traumatic brain injury.

The mouth-to-bag resuscitator during standard anaesthesia induction in apnoeic patients

Aim Ventilation of a non-intubated emergency patient by inexperienced rescuers with a standard bag-valve device may result in high inspiratory flow rates and subsequently high airway pressures with stomach inflation. Therefore, a self-inflating bag has been developed that requires lay rescuers to blow up a single-use balloon inside an adult bag-valve device, which, in turn, displaces air within the bag towards the patient. This concept has been compared to standard adult bag-valve devices earlier in bench models but not in patients. Methods An anaesthetist who was blinded to all monitor tracings ventilated the lungs of 40 apnoeic patients during routine anaesthesia induction either with a standard bag-valve device or with the mouth-to-bag resuscitator in a random order. Study endpoints were peak inspiratory flow rates, peak airway pressure, tidal volumes and inspiratory time. Results Peak inspiratory flow was 40 ± 10 l min −1 for the standard bag-valve device versus 33 ± 13 l min −1 for the mouth-to-bag resuscitator ( P < 0.0001); peak airway pressure was 17 ± 5 cmH 2O versus 14 ± 5 cmH 2O ( P < 0.0001); inspiratory tidal volume was 477 ± 133 ml versus 644 ± 248 ml ( P < 0.001) and inspiratory time was 1.1 ± 0.3 s versus 1.9 ± 0.6 s ( P < 0.0001). Conclusion Employing the mouth-to-bag resuscitator during simulated ventilation of a non-intubated patient in respiratory arrest significantly decreased peak inspiratory flow and peak airway pressure and increased inspiratory tidal volume and inspiratory times compared to a standard bag-valve device.

Effect of decreased inspiratory times on tidal volume

During cardiopulmonary resuscitation (CPR) with a chest compression rate of 60-100/min the time for secure undisturbed ventilation in the chest decompression phase is only 0.3-0.5 s and it is unclear which tidal volumes could be delivered in such a short time. Attempts were made to assess the tidal volumes that can be insufflated in such a short time window. In a bench model tidal volumes were compared in simulated non-intubated and intubated patients employing an adult self-inflating bag-valve with inspiratory times of 0.25, 0.3, and 0.5 s. Respiratory system compliance values were 60 mL/cmH(2)O being representative for respiratory system conditions shortly after onset of cardiac arrest and 20 mL/cmH(2)O being representative for conditions after prolonged cardiac arrest. With a respiratory system compliance of 60 mL/cmH(2)O, tidal volumes (mean+/-SD) in non-intubated versus intubated patients were 144+/-13 mL versus 196+/-23 mL in 0.25 s (p<0.01), 178+/-10 versus 270+/-14 mL in 0.3 s (p<0.01), and 310+/-12 mL versus 466+/-20 mL in 0.5 s (p<0.01). With a respiratory system compliance of 20 mL/cmH(2)O, tidal volumes in non-intubated patient versus intubated patients were 128+/-10 mL versus 186+/-20 mL in 0.25 s (p<0.01), 158+/-17 versus 250+/-14 mL in 0.3 s (p<0.01) and 230+/-21 mL versus 395+/-20 mL in 0.5 s (p<0.01). Ventilation windows of 0.25, 0.3, and 0.5 s were too short to provide adequate tidal volumes in a simulated non-intubated cardiac arrest patient. In a simulated intubated cardiac arrest patient, ventilation windows of at least 0.5 s were necessary to provide adequate tidal volumes.
