تماشاگران فیلم‎های احساسی و رمانتیک بیش از دوستداران فیلم‎های کمدی تمایل به خوردن تنقلات دارند. تحقیقات دانشمندان آمریکایی نشان می‎دهد تماشاگران فیلم‎های احساسی و رمانتیک بیش از دوستداران فیلم‌های کمدی تمایل به خوردن تنقلات دارند. 
 محققان در آزمایش اول به شرکت ‎کنندگان تنقلات داده و گروهی را به تماشای فیلم رمانتیک "Love Story" یا "داستان عشق" و گروه دیگر را به تماشای فیلم کمدی "Sweet Home Alabama" یا "مرا فراموش نکن" دعوت کردند. در پایان تحقیق معلوم شد گروهی که فیلم رمانتیک را تماشا کرده بودند ۳۶ درصد بیشتر از گروه دیگر تنقلات مصرف کرده‎اند. 
 در آزمایش دوم نیز محققان به شمارش زباله‎های پاپ کورن‎ها و دیگر تنقلات در سینماها پرداختند، در پایان تحقیقات انجام شده به این نتیجه رسیدند که تماشاگران فیلم رمانتیک "سولاریس" با بازی جرج کلونی، 55 درصد بیشتر از افرادی که فیلم کمدی "My Big Fat Greek Wedding" را تماشا کرده‎اند، ذرت بوداده خورده‎اند. نتایج این تحقیقات در مجله "JAMA Internal Medicine" نیز به چاپ رسید، بر اساس این تحقیق خوردن تنقلات احساس حزن و اندوه را از بین می‎برد.  

Emergency Pericardiocentesis

The use of emergency pericardiocentesis to aspirate fluid in patients with cardiac tamponade can be a lifesaving procedure that restores normal cardiac function and peripheral perfusion. This video demonstrates the procedure. Pericardiocentesis is indicated as an emergency procedure in patients with cardiac tamponade. Accumulation of fluid in the pericardial sac can increase the pressure around the heart. The intrapericardial pressure then increases until it equals the right ventricular diastolic pressure and then the left ventricular diastolic pressure which leads to impaired cardiac filling and decreased cardiac output

Central Venous Catheterization

The placement of a central venous line is an essential technique in the treatment of many hospitalized patients. This video will demonstrate the placement of a central venous catheter in the internal jugular vein with the use of one of several variations of the Seldinger technique. An additional video on subclavian line placement will be forthcoming. We will demonstrate and review the regional anatomy of the neck, indications for the insertion of a central line, the recommended site and technique for placement of a line in the internal jugular vein, selected complications associated with the procedure

Orotracheal Intubation

Emergency orotracheal intubation is indicated in any situation in which definitive control of the airway is needed. Specific indications include cardiac or respiratory arrest, failure to protect the airway from aspiration, inadequate oxygenation or ventilation, and impending or existing airway obstruction. Orotracheal intubation is also commonly performed as part of the care of the critically ill patient with multisystem disease or injuries, and to facilitate control of the airway during surgical procedures requiring general anesthesia. Contraindications: In emergent cases, such as cardiac arrest, airway management is of paramount importance, and there are very few contraindications to orotracheal intubation

Paracentesis

Abdominal paracentesis is performed as a diagnostic procedure to establish the etiology of new-onset ascites or to rule out spontaneous bacterial peritonitis in patients with preexisting ascites. Large-volume paracentesis is performed in hemodynamically stable patients with tense or refractory ascites to alleviate discomfort or respiratory compromise. Contraindications Many patients undergoing paracentesis will have baseline coagulopathy or thrombocytopenia. However, the incidence of clinically significant bleeding during paracentesis is extremely low, and routine use of fresh-frozen plasma or platelet concentrates is not recommended. Paracentesis should be avoided in patients with disseminated intravascular coagulation

Basic Laceration Repair

Lacerations are among the most common reasons for visits to emergency departments. Although most lacerations will heal without treatment, repair of these injuries reduces infection, scarring, and patient discomfort. Sutures, tissue adhesives, and wound tapes may all be used for laceration repair. Tissue adhesives and wound tapes are suitable for smaller lacerations that are not subject to substantial tension. In this video, however, we will demonstrate the use of simple interrupted sutures. Contraindications Not all lacerations are suitable for primary closure. Some should be allowed to heal by secondary intention (i.e., granulation and re-epithelialization)

Thoracentesis

Thoracentesis is used diagnostically to establish the cause of a pleural effusion. It can also be performed to drain large effusions that lead to respiratory compromise. Contraindications Limited data exist regarding the safety of thoracentesis in patients with coagulation abnormalities. The procedure is probably safe in patients with mild or moderate elevations of the prothrombin time or partial-thromboplastin time. The decision to use fresh-frozen plasma or platelet concentrates in patients with clinically significant coagulopathy or thrombocytopenia must be made on an individual basis

Lumbar Puncture

This video will demonstrate safe and successful methods of performing lumbar puncture. Lumbar puncture is indicated for both diagnostic and therapeutic purposes. Also, the administration of spinal and epidural anesthesia involves the use essentially of the same technique. Analysis of cerebrospinal fluid may be helpful in the diagnosis of infectious processes such as meningitis, inflammatory diseases such as multiple sclerosis, cancers such as leukemia, and metabolic processes. Therapeutically, lumbar puncture allows for the intrathecal administration of chemotherapeutic agents and antibiotics. There are specific contraindications to lumbar puncture

Male Urethral Catheterization

Urethral catheterization may be performed as either a therapeutic or a diagnostic procedure. Therapeutically, catheters may be placed to decompress the bladder in patients with acute or chronic urinary retention. In addition, catheters may be placed to facilitate bladder irrigation in patients with gross hematuria. Diagnostically, urinary catheters may be placed to obtain an uncontaminated urine sample for microbiologic testing, to measure urinary output in critically ill patients or during surgical procedures, or to measure post-void residuals. The only absolute contraindication to urethral catheterization is known or suspected urethral injury, usually in the setting of a pelvic fracture

Arthrocentesis of the Knee

Diagnostically, arthrocentesis is indicated to rule out septic arthritis in individuals presenting with a single or several inflamed joints. Arthrocentesis can also be used to differentiate between crystal arthropathies, such as gout and pseudogout, inflammatory and noninflammatory effusions, and hemarthroses. It should be emphasized that a single inflamed joint should almost always undergo at least one diagnostic aspiration. Therapeutically, arthrocentesis may be performed to drain large effusions, hemarthroses, or to inject steroids or local anesthetic. Arthrocentesis should be avoided in patients with cellulitis overlying the site of needle entry, out of concern of seeding the joint cavity with bacteria

Nasogastric Intubation

Common indications for nasogastric intubation include decompression of the GI tract in patients with bowel obstruction and gastric emptying in intubated patients to prevent aspiration. NG tubes may be placed as an adjunct for the delivery of oral agents, such as activated charcoal or oral radiographic contrast medium. NG tubes are often placed in patients with suspected upper GI hemorrhage. However, the sensitivity and negative predictive value of nasogastric aspirates for detecting active bleeding is suboptimal, and the absence of bloody return cannot be relied upon to rule out hemorrhage. Nonetheless, nasogastric intubation may be useful in selected patients

Placement of an Arterial Line

Arterial Line Placement (Introduction) This video will demonstrate arterial line placement in the radial artery using two of the many techniques available for arterial line placement, an over-the-wire technique and an over-the-needle technique. Placement of an arterial line is indicated for continuous monitoring of arterial pressure and direct arterial blood sampling. The radial pulse is palpated between the distal radius and the flexor carpi radialis tendon. Prior to line placement, perfusion of the extremity should be checked. For radial arterial catheters, an Allen test or a modified Allen test may be performed
