How Does an Eating Disorder Affect Your Physical and Mental Health and How It Is Related to Sleeve Gastrectomy?

Background Obesity is the pandemic of this era. At the same time, the commercialisation of thinness has also increased its adversity. Dissatisfaction with body shape is leading to many eating disorders. These disorders further cause several health problems. It has been found that individuals with eating disorders experience insomnia, depression, and anxiety. It also affects the endocrine system and digestive systems of the body. The surgical approach provides a more efficient treatment of obesity with sustainable results. Sleeve gastrectomy is the most popular surgical treatment. Sleeve gastrectomy is one of the prominent bariatric surgeries. Patients going through sleeve gastrectomy not only lose weight but also improve their mental health. Objective This study assesses the relationship between obesity, eating disorders, and physical health. It also focuses on the prevalence of sleeve gastrectomy procedures in such individuals and their outcomes. Methods This study used a cross-sectional design and a convenient sampling technique. The obese individuals who had eating disorders residing in Medina Al-Munawara and Riyadh city were taken as the samples. Online questionnaires were shared with participants to collect their perspectives on their weight, eating disorders, and their impact on physical health. The study collected both retrospective and present data. Results A total sample of 335 participants was taken, of which 181 (54%) were females and 154 (46%) were males, with a mean BMI of 28.85±2.57. The fear of weight gain was found among 265 (79%) of participants, 151 (45%) were feeling guilt while eating, 275 (82%) were weighing themselves daily, 325 (97%) were unable to stop eating even when complete, and 117 (35%) were unable to control themselves when they have food. As per the methods of avoiding weight gain, 166 (49.6%) were skipping a meal, 157 (47%) were following a diet, 17 (5%) were inducing vomiting, and 16 (4.8%) reused laxatives and diuretics. A total of 158 (47.2%) were involved in sports, but it was reduced to 61 (18.25%) upon sickness. Only 24 (7%) participants had undergone sleeve gastrostomy, and 181 (54%) believed that their cravings had increased, 238 (71%) complained of dizziness, and 151 (45%) believed that fast food caused gut unrest. Conclusion Obese individuals who are going through eating disorders are psychologically and physically compromised. They consider skipping meals to be the most efficient means of weight loss, and only a small percentage prefer to go for sleeve gastrectomy.

Assessing the Burden of Osteoarthritis in Africa and the Middle East: A Rapid Evidence Assessment.

Introduction/Objectives: This rapid evidence assessment (REA) was conducted to assess the burden of weight-bearing joint osteoarthritis in the developing countries of Africa and the Middle East. Methods: Our REA methodology used a standardized search strategy to identify observational studies, published between January 1, 2010, and April 23, 2020, reporting on outcomes pertaining to the epidemiology and humanistic or economic burden of weight-bearing osteoarthritis. Relevant data from the included studies were used for qualitative analysis. Results: Among the 20 publications reporting on knee osteoarthritis in 10 countries in Africa and the Middle East, 2 also reported on hip, and 1 on foot osteoarthritis. Prevalence of symptomatic/radiographic knee OA was 9-14% among rheumatology outpatients and 31-34% among those with mixed etiology osteoarthritis. Prevalence of knee OA diagnosed by magnetic resonance imaging was 70% among patients ≥40 years of age attending a hospital in Saudi Arabia. Quality-of-life outcomes were reported in 16 publications and suggested a substantial humanistic burden of osteoarthritis, including worse pain, function, and quality of life, and more depression; comparisons between studies were hampered by the variety of tools and scoring scales used, however. No studies reported on economic outcomes. Conclusion: This REA indicates a substantial burden of osteoarthritis in weight-bearing joints in Africa and the Middle East, consistent with publications from other regions of the world.

Pain Management in the Post-COVID Era-An Update: A Narrative Review.

An extensive computer search (from January 2020 to January 2023) was conducted including literature from the PubMed, Scopus, MEDLINE, Web of Science, and EMBASE databases. According to preset criteria, a total of 58 articles were included in this review article. Generally, any patient who becomes infected with COVID-19 can develop post-COVID-19 conditions. The course of COVID-19 is divided into three main stages: acute COVID-19 (up to 4 weeks), post-acute COVID-19 (from 4 to 12 weeks), and post-COVID (from 12 weeks to 6 months). If a more protracted course of COVID (over 6 months) is demonstrated, the term "long-COVID" is used. Although the acute stage of COVID-19 infection most commonly manifests with acute respiratory symptoms, one very common symptom of the disease is pain, while the most common symptoms of post-COVID syndrome are shortness of breath, dry cough, fatigue, loss of olfactory and gustatory function, tightness and chest pain, sleep and mood disturbances, body aches, muscle and joint pain, sore throat, fever, and persistent headaches. All observations demonstrated a high incidence of chronic pain syndromes of various localization in the post- and long-COVID period. Post-COVID chronic pain might include a newly developed chronic pain as a part of post-viral syndrome; worsening of preexisting chronic pain due to the associated changes in the medical services, or a de novo chronic pain in healthy individuals who are not infected with COVID. Chronic pain during and post-COVID-19 pandemic is an important health issue due to the significant impacts of pain on the patients, health care systems, and society as well. Therefore, it is important that patients with chronic pain receive effective treatment according to their specific needs. Accordingly, the main goal of this review article is to provide a broad description about the post-COVID pain and to explore the impact of long COVID-19 on chronic pain patients, and also to give brief reports about the prevalence, risk factors, possible mechanisms, different presentations, and the management tools through a systematic approach.

Efficacy of bupivacaine injection after pulsed radiofrequency ablation in the management of trigeminal facial pain: A prospective, randomized, and double-blind study.

OBJECTIVES: To assess the effect of bupivacaine application following pulsed radiofrequency (PRF) ablation on trigeminal facial pain. METHODS: A total of 73 patients with trigeminal facial pain refractory to conservative therapy were randomized into 2 groups. Group I subjects underwent PRF ablation procedure, followed by the injection of 1 ml of bupivacaine. Whereas, Group II underwent the same procedure followed by the injection of 1 ml of normal saline. Pain relief duration, the time of onset of pain relief, and analgesic effect evaluated by numerical pain rating scale were considered as outcomes. RESULTS: Thirty-nine patients in Group I and 34 in Group II. The duration of pain relief in the 2 groups was comparable (5 months in Group I vs. 6 months in Group II, p=0.53). The onset of pain relief in the patients of Group I was shorter than Group II (0 days vs. 4.5 days, p<0.001). The binary logistic regression analysis revealed that the application of bupivacaine alone had a significant effect on the reduction of the intake of medications (p<0.05). CONCLUSION: In situations involving patients who require rapid pain relief, bupivacaine injection following PRF ablation can be employed to provide immediate relief without subjecting the patients to the risks associated with major complications.

Post-amputation pain among lower limb amputees in a tertiary care hospital in Jeddah, Saudi Arabia: A retrospective study.

OBJECTIVES: To estimate the prevalence of post- amputation pain among lower-limb amputees and its burden on their lives. METHODS: A retrospective patients record review of lower limb amputation surgeries was carried out at King Abdulaziz University Hospital, Jeddah, Saudi Arabia, between 2008-2019. e collected data included: patients demographics, surgical operations, chronic pain characteristics, functional impairment, and treatment. RESULTS: A total of 645 lower-limb amputations carried out on 509 patients, 104 (20.4%) patients had more than one amputation surgery carried out, and 40 (7.9%) patients having bilateral amputations. The estimated prevalence of chronic post-amputation pain among the lower-limb amputees was approximately 61.5%. Persistent postoperative neuropathic pain was the most common type of pain following amputation, followed by residual limb pain, then phantom limb pain. The most common cause of amputation was diabetes and its related complications (76%). The mean age at surgery was 57.46±12.02 years. Although diabetes was a common comorbid illness (95.6%), it had no correlation with the development of chronic post-amputation pain. However, peripheral vascular disease had a strong association (p=0.009), especially with the development of phantom limb pain (54.5%; p=0.016). The most common reason for functional impairment among the amputees was disability (52.7%), while only 6.6% said it was secondary to pain. CONCLUSION: Post-amputation pain is one of the major consequences of amputation. Pain was poorly managed among these patients. Special considerations should be obtained to manage these patients' pain and reduce their suffering.

Saudi Heart Association, National Heart Center and National Cardiopulmonary Resuscitation Committee taskforce statement on CPR and resuscitation during COVID-19 pandemic.

Corona virus disease 2019 is a global pandemic, which affects around 2million individuals with a high death rate that exceeds 90,000 death cases across the globe. The Saudi Heart Association and the national cardiopulmonary resuscitation committee developed a taskforce to discuss the magnitude of clinical situation and CPR management on COVID-19 patients in a prehospital and in-hospital settings. Meanwhile, the taskforce aims to develop a nation-wide clinical guidance to be used by health care workers and untrained laypersons to resuscitate COVID-19 suspected and diagnosed patients.

Knowledge of Signs, Symptoms, Risk Factors, and Complications of Obstructive Sleep Apnea among Dental Interns.

Dentists are uniquely positioned to identify patients at risk of obstructive sleep apnea (OSA) and its complications. However, previous reports have shown that the average general dentist possesses insufficient knowledge about the clinical manifestations and complications of OSA. AIM: The purpose of this study was to examine Saudi dental interns' knowledge related to the clinical manifestations and impact of OSA. MATERIALS AND METHODS: This was a cross-sectional study using a self-administered questionnaire to assess the interns' knowledge related to the symptoms, signs, diagnosis, risk factors, and complications of OSA in adults and children. RESULTS: The average of the proportions of factually correct participant responses of the questionnaire categories was 47%. Participants did best in the category of questions related to predisposing factors (50% of questions were answered correctly), but less than 50% of questions were answered correctly in other OSA-related areas. Most participants scored 49% or lower in this questionnaire. CONCLUSION: Saudi dental interns had poor knowledge related to OSA. This may relate to the insufficiency of teaching sleep-related topics in dental curricula, among other reasons. CLINICAL SIGNIFICANCE: Given the potential impact of OSA on cardiovascular health, metabolic syndrome, and other public health problems, it is important to remedy this knowledge gap and empower future physicians with the knowledge required to participate in detecting OSA patients and referring them for evaluation.

Wet Cupping Reduces Pain and Improves Health-related Quality of Life Among Patients with Migraine: A Prospective Observational Study.

OBJECTIVES: To determine the benefits of wet cupping on pain and health-related quality of life (HRQOL) in adult patients with migraine headaches. METHODS: We conducted a prospective observational study of wet cupping in 128 patients referred to the cupping clinic at King Abdulaziz University Hospital, Jeddah, Saudi Arabia between January 2013 and December 2015. Bloodletting was performed at the base of the head and between the shoulders monthly four times. We assessed migraine headache pain using the visual analog scale (VAS) and the quality of life of patients before and after each cupping session using the World Health Organization Quality of Life assessment instrument. RESULTS: The mean age of the patients was 40.5±11.3 years with a preponderance of females (n = 114, 89.1%). VAS was averaged at 7 before the procedure and reduced to 3 after wet cupping, both during rest and activity (p ≤ 0.005). Ninety-five patients agreed to complete the quality of life questionnaire. There was a significant improvement in the quality of life after wet cupping treatment in most of the displayed items (p < 0.050). None of the patients reported post-procedure complications. CONCLUSIONS: Wet cupping might be considered a complementary treatment for migraine headache pain relief and improvement to a patient's quality of life.

Assessment of medical practitioners' knowledge of fibromyalgia in Saudi Arabia.

BACKGROUND: Fibromyalgia (FM), a relatively common disease, is difficult to diagnose owing to its subjective symptoms and poor knowledge among medical practitioners. The purpose of this study was to assess the knowledge regarding FM among medical practitioners in Saudi Arabia and the need for educational programs at the undergraduate level. SUBJECTS AND METHODS: An online survey was administered to physicians, nurses, and technologist/technicians in different regions of the country. Responses were obtained from 104 medical practitioners. Knowledge regarding FM including clinical symptoms, diagnosis, and treatment was assessed. RESULTS: Only 26% of the respondents reported that FM was part of their undergraduate curriculum, and only 8.7% attended educational programs about FM. (Approximately 50% of the medical practitioners either referred FM patients to unrelated specialty or did not know whom to refer these patients to). Only 33.7% of the respondents were familiar with the diagnostic criteria. Physiotherapy (69.4%) and pharmacological treatment (63.9%) were predominantly reported as the appropriate treatment. CONCLUSIONS: Knowledge regarding FM among medical practitioners in Saudi Arabia is poor. Further education at the undergraduate level is needed to improve knowledge and avoid delays in diagnosis and treatment.

An audit of in-hospital cardiopulmonary resuscitation in a teaching hospital in Saudi Arabia: A retrospective study.

OBJECTIVES: Data reflecting cardiopulmonary resuscitation (CPR) efforts in Saudi Arabia are limited. In this study, we analyzed the characteristics, and estimated the outcome, of in-hospital CPR in a teaching hospital in Saudi Arabia over 4 years. METHODS: A retrospective, observational study was conducted between January 2009 and December 2012 and included 4361 patients with sudden cardiopulmonary arrest. Resuscitation forms were reviewed. Demographic data, resuscitation characteristics, and survival outcomes were recorded. RESULTS: The mean ± standard deviation age of arrested patient was 40 ± 31 years. The immediate survival rate was 64%, 43% at 24 h, and 30% at discharge. The death rate was 70%. Respiratory type of arrest, time and place of arrest, short duration of arrest, witnessed arrest, the use of epinephrine and atropine boluses, and shockable arrhythmias were associated with higher 24-h survival rates. A low survival rate was found among patients with cardiac types of arrest, and those with a longer duration of arrest, pulseless electrical activity, and asystole. Comorbidities were present in 3786 patients with cardiac arrest and contributed to a poor survival rate (P < 0.001). CONCLUSIONS: The study confirms the findings of previously published studies in highly developed countries and provides some reflection on the practice of resuscitation in Saudi Arabia.

Determination of lumbosacral transitional vertebrae in kidney urinary bladder x-ray films in the Saudi population.

OBJECTIVES: To investigated the rate of occurrence of lumbosacral transitional vertebrae (LSTV), spinal variant, in kidney urinary bladder (KUB) plain radiographs in a Saudi population.  Methods: Between January 2012 to January 2015, KUB plain films obtained from patients at King Abdulaziz University Hospital, Jeddah, Saudi Arabia, were reviewed, and the presence or absence of LSTV was documented and classified as incomplete or complete. Patients who had evidence of spinal surgery that would obscure the view were excluded.  Results: A total of 2078 patients underwent KUB examinations during the study period; LSTV anomalies were detected in 158 of these. Sacralization was present in 153 (96.8%) of this cohort, while lumbarization was present in 5 (3.2%). A total of 136 (86.1%) of the sacralized segments were of the incomplete type, whereas 17 (10.7%) were complete. Of the lumbarized vertebrae, 3 (1.8%) were incomplete, and 2 (1.2%) were complete. The most frequent type in men was type Ib (28.5%) for sacralized segments, and type IIb for lumbarized segments (0.6%). In women, type Ia was the most common form of sacralized segments (11.3%) and type IIb was the most common form of lumbarized segments (2.8%). Conclusion: The prevalence of LSTV in Saudi patients is 7.6%, with a higher incidence of sacralization than lumbarization. Further studies with larger sample sizes and longer follow-up time are needed to demonstrate the clinical significance thereof.

The effect of wet cupping on quality of life of adult patients with chronic medical conditions in King Abdulaziz University Hospital.

OBJECTIVES: To assess the effect of wet cupping on health-related quality of life (HRQOL) of adult patients with chronic medical conditions, who were referred to the Cupping Clinic of King Abdulaziz University Hospital (KAUH), Jeddah, Kingdom of Saudi Arabia. Methods: A controlled, quasi-experimental study design was carried out among 629 patients referred for cupping from the KAUH Specialty Clinics, during the period from January to December 2014. Patients in the intervention group (309 patients) completed a pre-test included WHO quality of life-BREF, received one wet-cupping session, and filled-out the post-test (1 month later). Patients in the control group (320 patients) completed the pre-test during their enrollment in the study and post-test one month later. Both groups received their ordinary treatment. Descriptive and inferential statistics were performed.  Results: Pain was the most common cause for cupping referral. After cupping intervention, the mean scores of most of the HRQOL domains, especially the physical domain, improved significantly among patients in the intervention group. The mean total score of physical HRQOL domain was 61.6 ± 13.6 before cupping, and reached 69.7 ± 12.6 after intervention (paired t-test=11.3, p=0.000). Improvements in HRQOL were noticed for almost all types of pain and other medical conditions.  Conclusion: There are promising effects in favor of using wet cupping for improving HRQOL of patients with chronic conditions. Cupping is recommended as a complementary treatment modality for chronic medical conditions, especially pain.

Potential Relevance of Melatonin Against Some Infectious Agents: A Review and Assessment of Recent Research.

Melatonin, a tryptophan-derived neurohormone found in animals, plants, and microbes, participates in various biological and physiological functions. Among other properties, numerous in vitro or in vivo studies have reported its therapeutic potential against many parasites, bacteria and viruses. In this concern, melatonin was found to be effective against many parasites such as Plasmodium, Toxoplasma gondii, and Trypansoma cruzi, via various mechanisms such as modulation of calcium level and/or host immune system. Likewise, a recent investigation has reported in vitro activity of melatonin against Leishmania infantum promastigotes which is the causative agent of fascinating visceral Leishmaniasis. This review was initially undertaken to summarize some facts about certain physiological and therapeutic effects of melatonin. It also reviews the effects and action mechanisms of melatonin in bacterial and viral infection besides biology of different parasites which may provide a promising strategy for control of many diseases of public health importance.

Tracheal tube cuff inflation guided by pressure volume loop closure associated with lower postoperative cuff-related complications: Prospective, randomized clinical trial.

BACKGROUND: The main function of an endotracheal tube (ETT) cuff is to prevent aspiration. High cuff pressure is usually associated with postoperative complications. We tried to compare cuff inflation guided by pressure volume loop closure (PV-L) with those by just to seal technique (JS) and assess the postoperative incidence of sore throat, cough and hoarseness. MATERIALS AND METHODS: In a prospective, randomized clinical trial, 100 patients' tracheas were intubated. In the first group (n = 50), ETT cuff inflation was guided by PV-L, while in the second group (n. = 50) the ETT cuff was inflated using the JS technique. Intracuff pressures and volumes were measured. The incidence of postoperative cuff-related complications was reported. RESULTS: Demographic data and durations of intubation were comparable between the groups. The use of PV-L was associated with a lesser amount of intracuff air [4.05 (3.7-4.5) vs 5 (4.8-5.5), P < 0.001] and lower cuff pressure than those in the JS group [18.25 (18-19) vs 33 (32-35), P ≤ 0.001]. The incidence of postextubation cuff-related complications was significantly less frequent among the PV-L group patients as compared with the JS group patients (P ≤ 0.009), except for hoarseness of voice, which was less frequent among the PV-L group, but not statistically significant (P ≤ 0.065). Multiple regression models for prediction of intra-cuff pressure after intubation and before extubation revealed a statistically significant association with the technique used for cuff inflation (P < 0.0001). CONCLUSIONS: The study confirms that PV-L-guided ETT cuff inflation is an effective way to seal the airway and associates with a lower ETT cuff pressure and lower incidence of cuff-related complications.

Addition of dexmedetomidine to bupivacaine in transversus abdominis plane block potentiates post-operative pain relief among abdominal hysterectomy patients: A prospective randomized controlled trial.

BACKGROUND: Dexmedetomidine is an alpha 2 adrenergic agonist, prolongs analgesia when used in neuraxial and peripheral nerve blocks. We studied the effect of addition of dexmedetomidine to bupivacaine to perform transversus abdominis plane (TAP) block. MATERIALS AND METHODS: A total of 50 patients scheduled for abdominal hysterectomy were divided into two equal groups in a randomized double-blinded way. Group B patients (n = 25) received TAP block with 20 ml of 0.25% bupivacaine and 2 ml of normal saline while Group BD (n = 25) received 0.5 mcg/kg (2 ml) of dexmedetomidine and 20 ml of 0.25% bupivacaine bilaterally. Time for first analgesic administration, totally used doses of morphine, pain scores, hemodynamic data and side-effects were recorded. RESULTS: Demographic and operative characteristics were comparable between the two groups. The time for the first analgesic dose was longer in Group BD than Group B (470 vs. 280 min, P < 0.001) and the total doses of used morphine were less among Group BD patients in comparison to those in Group B (19 vs. 29 mg/24 h, P < 0.001). Visual analog scores were significantly lower in Group BD in the first 8 h post-operatively when compared with Group B, both at rest and on coughing (P < 0.001). In Group BD, lower heart rate was noticed 60 min from the induction time and continued for the first 4 h post-operatively (P < 0.001). CONCLUSIONS: The addition of dexmedetomidine to bupivacaine in TAP block achieves better local anesthesia and provides better pain control post-operatively without any major side-effects.

Melatonin administration in diabetes: regulation of plasma Cr, V, and Mg in young male Zucker diabetic fatty rats.

The use of melatonin, a neurohormone present in plants, represents an exciting approach for the maintenance of optimum health conditions. Melatonin administration ameliorates glucose homeostasis in Zucker diabetic fatty (ZDF) rats. The objective of this study was to investigate the effects of melatonin in diabetes in relation to the levels and regulation of plasma chromium (Cr), vanadium (V), and magnesium (Mg) in Zucker diabetic fatty (ZDF) and Zucker lean (ZL) rats. At the age of 6 weeks, ZDF (n = 30) and ZL (n = 30) groups were each subdivided into three groups: control (C) (n = 10), vehicle-treated (V') (n = 10) and melatonin-treated (M) (10 mg kg(-1) per day; n = 10) groups for a 6 week period. After treatment, plasma mineral concentrations were measured by flame (Mg) and electrothermal (Cr and V) atomic absorption spectrometry. No significant differences were found between the C and V' groups (p > 0.05). Plasma Mg levels were significantly lower in C-ZDF vs. C-ZL rats, demonstrating the presence of hypomagnesemia in this diabetes mellitus model. Plasma V and Cr levels were significantly higher in M-ZDF vs. C-ZDF rats. Plasma Mg levels in ZDF rats were not affected by melatonin treatment (p > 0.05). Melatonin administration ameliorates the diabetic status of ZDF rats by enhancing plasma Cr and V concentrations. This appears to be the first report of a beneficial effect of melatonin treatment on plasma Cr and V regulation in ZDF rats.

A survey of the practice of regional anesthesia in Saudi Arabia.

OBJECTIVE: This survey aimed to assess both the extent of practice and need for training in regional anesthesia among anesthesiologists in Saudi Arabia in 2012. METHODS: We distributed an electronic survey among 382 anesthesiologists attending the bi-annual meetings of the Saudi Anesthetic Association, enquiring about their practice in regional anesthesia. Questions concerned the practice of regional anesthesia, use of ultrasound guidance, and the need for training workshops. RESULTS: The response rate of anesthetists was 55.2% with most of them were males and had mean age of 25-50 years. Most anesthesiologists (88.2%) were practicing regional anesthesia frequently in the operating rooms (75.3%) rather than designated block room. From the respondents, only 14.2% did fellowship in regional anesthesia, 21.8% and 18.5% were using ultrasound and nerve stimulation guidance, respectively, 11.4% received formal training, and 86.3% were willing to attend training workshops on regional anesthesia. There was a significant negative correlation between the ultrasound users and their institutional positions (r=-0.191) (P=0.026). CONCLUSIONS: We believe that more could be done to improve the practice of regional anesthesia in the Kingdom of Saudi Arabia, including the implementation of formal training and conduction of more frequent specialized courses/workshops in the field of regional anesthesia with special reference to ultrasound regional anesthesia blockade techniques.

Use of pressure volume loop closure to check for endotracheal tube cuff function. Randomized clinical trial.

OBJECTIVE: To assess the efficacy of pressure volume loop (PV-L) closure as an indicator of adequate endotracheal tube cuff (ETTc) function, and to compare this with commonly used methods of checking cuff pressure. METHODS: We conducted a randomized clinical trial at the Department of Anesthesia, King Abdulaziz University Hospital, Jeddah, Kingdom of Saudi Arabia from October 2011 to February 2012. One hundred and forty patients were intubated, and the ETTc was inflated using one of 3 techniques. The intubating anesthesiologist inflated the cuff at his discretion until he detected no further air leak in the first technique. In the second technique, we maintained the ETTc pressure at 20 centimeter water, while the third technique used PV-L closure. RESULTS: The PV-L technique required lower amounts of air to inflate the ETTc than the other 2 techniques (3.89+/-0.26 for PV-L versus 4.4+/-0.36 for fixed preset pressure, and 5.26+/-0.46 for pilot balloon palpation, p=0.00001) and the mean cuff pressure was lower than other techniques (18.67+/-0.72 for PV-L versus 20 for fixed preset pressure, and 33.48+/-3.49 for pilot balloon palpation, p=0.00001). CONCLUSION: The PV-L closure technique is an alternative way to check for ETTc function with a significantly lower ETTc pressure and volume than those recorded with a manually inflated cuff, or with preset cuff pressure of 20 cmH2O.
