1/24. Accumulation of irrigation fluid in the calf as a complication during high tibial osteotomy combined with simultaneous arthroscopic anterior cruciate ligament reconstruction.Extravasation of irrigation fluid during arthroscopy is a well-known complication. We report a case of accumulation of fluid into the calf during open wedge high tibial osteotomy combined with simultaneous arthroscopic anterior cruciate ligament (ACL) reconstruction. The main cause for fluid extravasation was the drilling of the tibial tunnel, which allowed the fluid to cross the osteotomy gap and invade the flexor compartments. Although an elevation of the intracompartmental pressure was measured, there was no clinical evidence of compartment syndrome. A subcutaneous release of the flexor compartment of the leg was performed. The patient suffered no further sequelae. High tibial osteotomy combined with simultaneous arthroscopic ACL reconstruction has to be performed carefully, and potential complications must be detected immediately to prevent compartment syndrome.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
2/24. Perioperative management of a patient presenting with a spontaneously ruptured esophagus.PURPOSE: To report a case of spontaneous rupture of the esophagus and its anesthetic management. CLINICAL FEATURES: A 52-yr-old male presented with a seven day history of chest pain, respiratory distress, and swelling in the neck following forceful vomiting. Examination revealed hypotension, decreased air entry in the right lower lung field with crepitations, epigastric tenderness with abdominal distension and guarding of both right and left hypochondria. A contrast esophagogram showed extravasation of contrast material from the lower third of the esophagus into the mediastinum without pleural cavity involvement. Reinforced primary closure of a 5-cm transmural tear in the right anterolateral wall of the esophagus 5 cm above the gastro-esophageal junction was performed along with right-sided chest drainage. The anesthetic drugs and technique in this case were selected to avoid any increase in intra-abdominal pressure to prevent further spillage of gastric contents into the mediastinum through the perforation. Invasive monitoring was used to assess early hemodynamic changes and to administer fluid therapy and vasoactive drugs. Due to prolonged surgery, lung congestion, large fluid shifts, a long surgical incision and abnormal arterial blood gases, the patient was ventilated mechanically in the intensive care unit. Subsequently he developed an esophageal leak, septic shock, and multiple organ failure and died. CONCLUSION: In a patient with a spontaneous rupture of esophagus, the anesthetic considerations include avoidance of further aggravation of the esophageal tear, and resuscitation from a morbid inflammatory condition.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
3/24. Purple glove syndrome: a complication of intravenous phenytoin.Intravenous phenytoin, available for use since 1956, has several well known adverse effects, such as hypotension, arrhythmias and toxicity. Purple glove syndrome is a less common complication that can have serious consequences. Fasciotomies, amputations and permanent disuse of the hand and forearm have been reported. The etiology of purple glove syndrome is still unknown, but possible etiologies and risk factors have been suggested. Three stages of purple glove syndrome have been identified: appearance, progression and resolution. During the second stage, progression, purple glove syndrome can be identified as either mild or severe. Mild cases may heal uneventfully when nursing measures such as elevation, application of dry, gentle heat and measures to prevent secondary injury are instituted. Severe cases may require emergency surgical intervention such as fasciotomy to relieve pressure and restore blood flow. Therapeutic nursing interventions aimed at maximizing healing and promoting comfort are essential.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
4/24. Treatment of peripheral tissue ischemia with topical nitroglycerin ointment in neonates.Four neonates had resolution of peripheral tissue ischemia after the application of 2% nitroglycerin ointment. A dosage of 4 mm nitroglycerin ointment per kilogram of body weight was applied to two patients with ischemia caused by vasospasm from indwelling radial artery catheterization and to two patients with ischemia resulting from dopamine extravasation. No adverse effects were noted except mild episodes of decreased blood pressure in two of the patients.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
5/24. Management of barium enema-induced colorectal perforation.Unless recognized and treated promptly, colorectal perforation induced by barium enema examination is a life-threatening complication. Between 1977 and 1986, 13,000 barium enemas were performed at the Mayo Medical Center. Colorectal perforation occurred in five patients (overall incidence: 0.04%). The two colonic perforations were managed by immediate celiotomy with resection in one and primary repair in the other. The three rectal perforations were managed conservatively in two patients and by proximal diversion in one. All patients recovered. Perforations were believed to be related to the tip of the enema catheter or presumably to excessive hydrostatic pressure. In contrast to other reports, barium enema-induced colorectal perforation is not always fatal when recognized early and treated aggressively. Localized, contained extraperitoneal rectal perforation may be managed conservatively in selected patients.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
6/24. Inferior alveolar nerve injury caused by thermoplastic gutta-percha overextension.Injuries to the inferior alveolar nerve following trauma resulting in a mandibular fracture are well documented and are a well-known risk when surgical procedures are planned for the mandible in the region of the inferior alveolar canal. Such injuries are relatively rare following endodontic therapy. This article reports a case of combined thermal and pressure injury to the inferior alveolar nerve, reviews the pathogenesis of such an injury and makes suggestions for its management.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
7/24. Vesicouterine fistulas: imaging findings in three cases.OBJECTIVE: The objective of our report is to present three cases of vesicouterine fistulas secondary to a cesarean delivery, a uterine rupture during labor, and radiation therapy. The delay between the onset of symptoms and the diagnosis varied between 3 and 7 years. Different techniques such as color Doppler sonography, excretory urography, cystography, CT, MRI, cystoscopy, vaginoscopy, and hysterography were performed with variable results, mostly negative and sometimes undefined. CONCLUSION: The definitive diagnosis was made with contrast-enhanced helical CT after cystography in one case, unenhanced helical CT after hysterography in another case, and cystography in the third case. Vesicouterine fistula rarely is thought of in the differential diagnosis because of its rarity and negative results on radiologic and endoscopic tests. The diagnosis is made on imaging after opacification of the uterus or the bladder depending on the pressure gradient obtained and the location of the fistula in relation to the uterine isthmus.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
8/24. Extravasation injury in the perioperative setting.Extravasation is an unintentional injection or leakage of fluid in the perivascular or subcutaneous space. Extravasation injury results from a combination of factors, including solution cytotoxicity, osmolality, vasoconstrictor properties, infusion pressure, regional anatomical peculiarities, and other patient factors. We reviewed the hospital files of patients who had sustained a significant extravasation injury in the perioperative setting at two German hospitals. These cases highlight the risk of devastating consequences from extravasation injury. Vasoactive drugs and hyperosmolar and concentrated electrolyte solutions are the predominant vesicants in the perioperative setting. Prompt and appropriate intervention is important for avoiding or minimizing extensive tissue injury.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
9/24. Extravasation of the contrast media during voiding cystourethrography in a long-term spinal cord injury patient.OBJECTIVE: To present complications and pitfalls in voiding cystourethrography (VCUG) and introduce a guideline for performing VCUG in a long-term spinal cord injury (SCI) patient with neurogenic bladder dysfunction (NBD) and contracted bladder. STUDY DESIGN: A case report. SETTING: Maharaj Nakorn Chiang Mai Hospital, Chiang Mai, thailand. METHOD: We describe a chronic C(5) tetraplegic man with NBD and contracted bladder, who developed autonomic dysreflexia (AD), gross hematuria and extravasation of contrast median during VCUG. RESULT: A foley catheter was retained after VCUG. AD was resolved and urine cleared after a week of continuous bladder irrigation. CONCLUSION: VCUG should be performed with caution in a long-term SCI patient with NBD and contracted bladder. Forceful pushing of the contrast media by the hand-injection method caused abrupt distention of the contracted bladder, damaged bladder mucosa and aggrevated AD. We suggest a guideline as follows: report bladder capacity and AD, if present, in an X-ray requisition form; use the gravity-drip method, stop the drip and drain the contrast media if a sudden headache and rising of blood pressure (BP) develop; observe urine colour, and report if bleeding or AD occurs.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
10/24. Severe hypertension after stellate ganglion block.Haemodynamic effects may occur after stellate ganglion block (SGB) arising from autonomic imbalance and local anaesthetic infiltration to barosensitive areas. We report seven patients who developed severe hypertension (systolic arterial pressure >200 mm Hg) after SGB in our pain clinic service. We postulate that diffusion of the local anaesthetic along the carotid sheath may produce vagal blockade causing unopposed sympathetic activity as a result of attenuation of the baroreceptor reflex. We recommend close monitoring of arterial pressure measurement in patients who received SGB.- - - - - - - - - - ranking = 2keywords = pressure (Clic here for more details about this article) |
