PURPOSE: Although bilevel positive airway pressure (Bilevel PAP) therapy is usually used for overlap syndrome (OS), there is still a portion of OS patients in whom Bilevel PAP therapy could not simultaneously eliminate residual apnea events and hypercapnia. The current study was expected to explore whether auto-trilevel positive airway pressure (auto-trilevel PAP) therapy with auto-adjusting end expiratory positive airway pressure (EEPAP) can serve as a better alternative for these patients...

The holistic self-management plan includes lifelong actions that enable patients to cope with their disease. The present study was designed to evaluate the effect of a holistic self-management plan on asthma control. A 12-month controlled study was conducted. Adult patients with mild-to-moderate asthma (n = 24) who attended the emergency asthma department were randomized to two groups: One group followed four educational sessions and three personal home sessions (n = 12), while a second group received a short manual with asthma information (n = 12)...

Lovina Neil, Ashok Patel
INTRODUCTION: Dexmedetomidine, an α2 agonist, can be used as an adjuvant in general anaesthesia as it attenuates the stress response to various noxious stimuli and helps in maintaining the perioperative haemodynamic stability along with sedation and not causing any significant respiratory depression in the postoperative period. AIM: To study the difference in haemodynamic responses of dexmedetomidine and fentanyl in patients undergoing laparoscopic surgery. MATERIALS AND METHODS: Sixty patients were divided into two groups of 30 each randomly...

OBJECTIVE: Serum bicarbonate reflects dehydration severity in children with gastroenteritis. Previous work in children receiving intravenous rehydration has correlated end-tidal carbon dioxide (EtCO2) with serum bicarbonate. We evaluated whether EtCO2 predicts weight change in children with vomiting and/or diarrhea. METHODS: A prospective cohort study was conducted. Eligible children were 3 months to 10 years old and presented for emergency department (ED) care because of vomiting and/or diarrhea...

REVIEW
Christine M Riley
Capnography or end-tidal carbon dioxide (Etco2) monitoring has a variety of uses in the pediatric intensive care setting. The ability to continuously measure exhaled carbon dioxide can provide vital information about airway, breathing, and circulation in critically ill pediatric patients. Capnography has diagnosis-specific applications for pediatric patients with congenital heart disease, reactive airway disease, neurologic emergencies, and metabolic derangement. This modality allows for noninvasive monitoring and has become the standard of care...

BACKGROUND: Prolonged pneumoperitoneum and Trendelenburg positioning for robot-assisted radical cystectomy (RARC) are essential for optimizing visualization of the operative field, although they worsen hemodynamic and respiratory function. Our hypothesis is that the use of a valveless trocar (VT) may improve respiratory mechanics. METHODS: In this prospective, 2-arm parallel trial, patients ASA II to III undergoing RARC were randomly assigned into 2 groups: in the VT group, the capnoperitoneum was maintained with a VT; in the control group, the capnoperitoneum was maintained with a standard trocar (ST group)...

OBJECTIVE: PaCO2 affects cerebral blood flow (CBF) and its regulatory mechanisms, but the effects of CO2 measurement technique on cerebrovascular parameters are unknown. In order to determine if the two most commonly used approaches, face mask (FM) or nasal cannulae (NC), are interchangeable or not, we tested the hypothesis that the use of FM versus NC does not lead to significant differences in CO2-related systemic and cerebrovascular parameters. APPROACH: Recordings of CBF velocity (CBFV), blood pressure (BP), heart rate, and end-tidal CO2 (EtCO2) were performed in 42 subjects during normocapnia (FM or NC) and 5% CO2 inhalation (FM) or hyperventilation (NC)...

OBJECTIVES: We sought to examine the physiological impact the apneic period has on the respiratory physiology of patients undergoing intubation in the emergency department and whether DAO, the delivery of 15L oxygen by nasal cannula during apnea, can affect the development of respiratory acidosis. METHODS: This was a prospective observational cohort study conducted at an urban academic level 1 trauma center. A convenience sample of 100 patients was taken. Timed data collection forms were completed during the periintubation period...

INTRODUCTION: Children with Down syndrome (DS) have a high incidence of obstructive sleep apnea (OSA) that is often associated with hypoventilation. Little is known, however, about the prevalence of sleep-associated hypoventilation independent of OSA in these children. METHODS: Retrospective chart review of all children with DS under 18 years of age undergoing polysomnography at a tertiary care paediatric hospital during a 2-year period. Exclusion criteria were as follow: those requiring oxygen or positive-pressure ventilation; with tracheostomy, baseline hypoxia, unrepaired cyanotic heart disease, pulmonary hypertension, and cerebral palsy; or OSA with >5 obstructions/hour...

INTRODUCTION: A sustained and effective oropharyngeal sealing with supraglottic airway is required to maintain the ventilation during laparoscopic surgery. Previous studies have observed the Oropharyngeal Seal Pressure (OSP) for Proseal Laryngeal Mask Airway (PLMA) after pneumoperitoneum in supine and trendelenburg position, where PLMA was found to be an effective airway device. This study was conducted with ProSeal LMA, for laparoscopic Urologic procedures done in lateral position. AIM: To measure OSP in supine and lateral position and to observe the effect of pneumoperitoneum in lateral position on OSP...

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...

Cerebrovascular CO2 reactivity is affected by nitric oxide (NO). We tested the hypothesis that sildenafil selectively potentiates NO-cGMP signaling affects CO2 reactivity. Fourteen healthy males (34±2 years) were enrolled in the study. BP, ECG, velocity of cerebral blood flow (CBF, measured by TCD), end tidal CO2 (EtCO2) were assessed at baseline (CO2 ~ 39 mm Hg), during hyperventilation (CO2 ~ 24 mm Hg), hypercapnia (CO2 ~ 46 mm Hg), boluses of phenylephrine (25-200 µg) and during graded head-up tilting (HUT)...

RATIONALE: Pulmonary arterial hypertension (PAH) is characterized in part by increased dead space ventilation, which can be estimated noninvasively at the bedside by measurement of end-tidal CO2 (ETco2). OBJECTIVES: Prior work has demonstrated that ETco2 is lower in patients with PAH than in control patients, but whether ETco2 has prognostic value is unknown. We hypothesized that lower measurements of ETco2 in patients with PAH correlate with worse long-term outcomes...
