Childhood airway manifestations of lymphangioma: a case report.

Lymphangioma is a congenital malformation of the lymphatic system, often involving areas of the head and neck. The involved structures may include enlarged tongue and lips, swelling of the floor of the mouth, and direct involvement of the upper respiratory tract. The definitive treatment for lymphangioma is surgery, often during the first years of life. Despite surgical removal, lymphangioma may persist. Anesthetic concerns include bleeding, difficulty visualizing the airway, extrinsic and intrinsic pressure on the airway causing distortion, and enlarged upper respiratory structures, including the lips, tongue, and epiglottis. This is a case report of a 9-year-old patient with lymphangioma who had impacted teeth and a suspected odontogenic cyst. There seems to be little information on the optimal anesthetic management for this age group. The challenges with airway management, including bleeding, laryngospasm, and a difficult intubation, are outlined. Awareness of potential airway involvement and possible complications is necessary to provide a safe anesthetic to a patient with lymphangioma. A review of the literature, airway management techniques, and current airway equipment will be discussed.

Air embolism during anaesthesia for shoulder arthroscopy.

We report a case of venous air embolism during an elective shoulder arthroscopy in which air was used as a joint distending agent. Venous air embolism was diagnosed by the sudden decrease in the end-tidal carbon dioxide concentration. The patient suffered no serious complications of venous air embolism and made a full recovery. We present this case to make surgeons and anaesthetists aware of the possibility of gas/air embolism during elective arthroscopy, when gas/air is used to distend the joint. This case also illustrates that the end-tidal carbon dioxide monitor, which is part of the standard anaesthetic monitoring system, is very sensitive in detecting venous air embolism.

Anaesthetic assistants: their role in the development and resolution of anaesthetic incidents.

Trained anaesthetic assistants are considered essential for the safe conduct of anaesthesia. Data from 5837 AIMS (Anaesthetic Incident Monitoring Study) reports were evaluated for issues concerning anaesthetic assistants in the generation and resolution of anaesthetic incidents. "Inadequate assistance" as a contributing factor was identified in 187 reports, whilst "skilled assistance" which minimized the incident was present in 808 cases. One hundred and seventy-two reports specifically commented on anaesthetic assistants in the narrative section of the AIMS form. All surgical specialties were represented. In 147 of these reports the assistant actually contributed to or failed to assist with the incident. Although the majority of outcomes from the reports were uneventful, prolonged stay, awareness and ICU admission did ensue in a small number of cases. The most common incidents were related to problems with equipment, communication and inadequate staffing levels (number and/or skill mix). Results from this study have implications for anaesthetic assistant staffing levels and the orientation of course content.

Intracerebral hemorrhage remote from the site of the initial neurosurgical procedure.

Four cases of intracerebral hemorrhage remote from the site of the initial neurosurgical procedure are presented. Two of the four patients had preoperative hypertension. Possible mechanisms are discussed, and labile hypertension and unstable blood pressure during the perisurgical period may be contributory. Clinical awareness of this rare but potential complication is essential to early diagnosis and treatment. Difficulty in awakening from anesthesia and the development of new neurological deficits not attributable to the operative site are the most important keys to early diagnosis. Computed tomography is the diagnostic method of choice.

Triple arthrodesis.

Triple arthrodesis is a useful operation for the relief of chronic pain and repair of instability and deformity in the rearfoot. Due to the nature of the procedure, preoperative surgical planning is of extreme importance to minimize the incidence of long-term problems associated with rearfoot fusion. Complete intraoperative reduction of the deformity and stable rigid fixation is necessary to avoid complications associated with arthrodesis failure and any long-term problems in neighboring joints, particularly in the ankle joint and joints of the mid- and forefoot. Even with good reduction and fixation, there is still the possibility of nonunion or painful pseudoarthrosis. Gait alterations that may lead to residual pain and degenerative joint disease can also be seen. While these problems can occur, they might not be as symptomatic as the patients' preoperative complaints. The surgeon, however, needs to be aware that these conditions exist and may need to be addressed in the long-term care of the patient.

Ampullary disconnection during the course of biliary and duodenal surgery.

Ampullary disconnection is fortunately rare. As this experience indicates, the long-term salvage rate is good but demands immediate recognition, precise repair and frequently reoperation to obtain a satisfactory result. One should be aware that the ampulla may be located very proximally in patients with long-standing peptic ulceration. The common duct should be catheterized while reoperation is required in this area in cases of obscured anatomy of the distal bile and pancreatic ducts.

The short-lasting analgesia and long-term antihyperalgesic effect of intrathecal clonidine in patients undergoing colonic surgery.

UNLABELLED: In this study, we investigated the antihyperalgesic effect of clonidine after surgery. Sixty patients undergoing right colic resection were studied. Patients were randomized to receive prior to general anesthesia a 2-mL intrathecal (IT) injection of 300 microg of clonidine or saline, or 10 mg of bupivacaine. General anesthesia was achieved using a target concentration propofol infusion and monitored using bispectral index. Postoperative analgesia was provided by morphine IV given through a patient-controlled analgesia device. Postoperative analgesia was assessed by morphine requirements and visual analog scale pain scores at rest, cough, and movement during the first 72 h. Mechanical hyperalgesia was measured by von Frey filaments. Patients were questioned regarding residual pain at 2 wk,1, 6, and 12 mo. The patient-controlled analgesia morphine requirements were significantly smaller in the IT clonidine group (31.5 +/- 12 versus 91 +/- 25.5 and 43 +/- 15 mg, respectively, in groups clonidine, saline, and bupivacaine: P < 0.05 at 72 postoperative hours). The area of hyperalgesia at 72 h was 3 +/- 5 cm(2) in the clonidine group versus 90 +/- 30 and 35 +/- 20 cm(2) in the saline and bupivacaine groups (P < 0.05). At 6 mo, fewer patients in the clonidine group experienced residual pain than in the saline group (0 of 20 versus 6 of 20, P < 0.05). We conclude that both intraoperative spinal clonidine and bupivacaine improve immediate postoperative analgesia. IT clonidine was, however, more potent than IT bupivacaine to reduce postoperative secondary hyperalgesia. IMPLICATIONS: Spinal clonidine contributes to the reduction of secondary hyperalgesia in patients recovering from abdominal surgery.

Symptomatic pneumorachis associated with incidental durotomy during microscopic lumbar disc surgery. Case report.

Unintended incidental durotomy is not a rare complication of lumbar microsurgery and is usually recognized and treated immediately. The reconstruction process can be complicated further by unpredictable factors. To their knowledge, the authors report the first case of a symptomatic pneumorachis associated with the accidental awakening of a patient during reconstruction of an incidental durotomy following lumbar microdiscectomy. Incomplete cauda equina syndrome developed in the patient on awakening from surgery after reconstruction of an unintended incidental dural tear that occurred during lumbar microdiscectomy. Symptomatic pneumorachis was revealed on an emergency computed tomography scan, and the patient underwent immediate repeated operation to remove air and decompress the spinal canal. The increasing number and complexity of surgical procedures in the lumbar spine contribute to the growing incidence of unintended durotomy. The surgeon should be aware of rare complications that may arise. Development of a vacuum phenomenon in conjunction with a ball-valve mechanism may lead to pneumorachis during durotomy repair. If this rare complication is promptly recognized and confronted, the outcome will not be associated with long-term sequelae.

Minimizing the use of homologous blood products during repair of abdominal aortic aneurysms.

The recent threat of post-transfusion AIDS and increased awareness of blood-related hepatitis have compelled surgeons to minimize the use of homologous blood products during aortic aneurysm repair. Reducing or eliminating homologous blood transfusion can be achieved by aggressive attention to three aspects of patient care: (1) routine use of autologous transfusion; (2) careful surgical technique, emphasizing the minimum dissection needed to expose the aneurysm adequately; and (3) a higher threshold for use of any blood products. In a prospective study of 100 consecutive aortic reconstructions, 80 per cent of patients undergoing aneurysm repair received only their own blood during hospitalization. Routine intraoperative autologous red-cell salvage has also conserved the bank blood supply by reducing usage of homologous blood by 75 per cent. The key to minimizing homologous blood requirements for aneurysm repair has been the development of rapid cell-washing autotransfusion devices.

Perioperative fluid therapy in children: a survey of current prescribing practice.

BACKGROUND: Fluid therapy in children may be associated with iatrogenic hyponatraemia. We surveyed anaesthetists' current fluid prescribing practice during the perioperative period, departmental fluid protocols and awareness of the concerns of the Royal College of Paediatrics and Child Health (RCPCH) about the use of dextrose 4%/saline 0.18% in children. METHODS: Questionnaire survey of 477 consultant anaesthetists in two training areas in the UK. RESULTS: Responses were received from 289 anaesthetists (60.6%)--responses from the 203 consultants that anaesthetized children were analysed. A total of 67.7% did not have a local departmental policy for fluid prescription, and 58.1% were unaware of the concerns of RCPCH. A total of 60.1% of anaesthetists said that they prescribed hypotonic dextrose saline solutions in the intraoperative period and 75.2% did so in the postoperative period. Anaesthetists working in specialist paediatric hospitals were 5.1 times more likely to prescribe isotonic fluids intraoperatively than those working in district hospitals (95% CI 1.48-17.65, P=0.01), but they all prescribed hypotonic dextrose saline solutions postoperatively. The Holliday and Segar formula for maintenance fluid was quoted by 81.8% of anaesthetists; only 5.9% of anaesthetists would restrict fluids in the immediate postoperative period. Anaesthetists working in specialist paediatric hospitals were 13.2 times more likely to restrict fluids postoperatively than those working in district hospitals (95% CI 2.8-61.8, P=0.001). CONCLUSIONS: The prescription of hypotonic dextrose saline solutions by anaesthetists may be putting children at risk from iatrogenic hyponatraemia. Departmental protocols for perioperative fluid prescription in children are uncommon. We suggest that national guidance is required.

Intracerebral pneumocephalus and hemiparesis as a complication of a halo vest in a patient with multiple myeloma. Case report.

A halo orthosis is often used to immobilize the cervical spine after severe injury in patients who cannot tolerate surgery. Although complications such as pin loosening or brain abscess have been reported, there are no reported cases of hemiparesis following pneumocephalus associated with halo use. The authors report the case of a 77-year-old man with multiple myeloma who, after undergoing halo vest therapy and chemotherapy, suddenly developed hemiparesis and speech disturbance. Diagnostic neuroimaging demonstrated penetration of the inner table at the right posterior pin site and intracerebral pneumocephalus at the parietal lobe. Intraoperative inspection revealed only air and no purulent materials or cerebrospinal fluid in the cystic lesion. When a halo device is used, attention to detail in pin application, maintenance, and proper pin-site care must be undertaken to minimize complications. The tightening of the pin in cases in which late-onset loosening has occurred should not be performed. Additionally, because late loosening of the pin and pin-site infection increase the risks of complications, a halo vest should be used only as a short-term treatment, and the clinician should be aware of the possible increased risk of serious complications such as pneumocephalus or subdural abscess formation.

Primary adenocarcinoma of the gallbladder presenting as primary gynecologic malignancy: a report of two cases.

BACKGROUND: Carcinoma metastatic to the uterus from extragenital sites is rare. Such metastatic disease is typically diagnosed at autopsy or in patients with known primary malignancies. This report discusses two cases of primary carcinoma of the gallbladder presenting as abnormalities in gynecologic screening procedures. CASES: A 71-year-old woman presented with postmenopausal bleeding. Uterine curettage revealed poorly differentiated adenocarcinoma of presumed endometrial origin. Intraoperative frozen-section analysis of the uterus showed carcinoma involving the lymphatics, but no primary tumor. Further exploration revealed primary adenocarcinoma of the gallbladder, with widespread metastases. The second case was a 67-year-old asymptomatic woman. Routine cervical cytology showed adenocarcinoma, but tissue studies were negative. She developed jaundice 1 month later. Computed tomography of the upper abdomen revealed a mass in the gallbladder fossa, and needle biopsy of the lesion showed adenocarcinoma. CONCLUSIONS: Metastatic carcinoma of non-genital tract origin may present as primary gynecologic malignancy. The physician should be aware of the implications of both the common and unusual interpretations of screening and diagnostic procedures. When the clinicopathologic presentation is atypical, a thorough knowledge of the differential diagnoses of abnormal test results allows appropriate and expeditious patient management.

Liver abscess after hemorrhoidectomy. Report of two cases.

PURPOSE: Pyogenic liver abscess after hemorrhoidectomy is extremely rare. Only two such cases have been previously reported; the diagnosis in each was made intraoperatively. We report two additional cases of hepatic abscess after hemorrhoidectomy, both treated nonoperatively with a successful outcome. METHODS: The two cases were analyzed for history, presentation, laboratory data, radiologic studies, and bacteriology. RESULTS: In both cases, the patients presented within one week of the hemorrhoidectomy. Treatment with broad-spectrum intravenous antibiotics was successful in achieving significant clinical improvement. The liver function test values reverted back to normal and follow-up computed tomography (CT) scans of the liver revealed marked improvement of the abscesses. Laparotomy was avoided in both of the patients. CONCLUSIONS: Increased awareness of this serious complication will afford earlier diagnosis. In addition, proper aerobic and anaerobic bacterial isolation techniques will allow appropriate nonoperative therapy, decreasing the high morbidity and mortality rates associated with this complication.

Femoral nerve palsy after mandibular reconstruction with microvascular iliac flap: a complication under anticoagulation therapy.

Pharmacological prophylaxis and intervention are used extensively in head and neck reconstructions with microvascular flaps. There is no universally accepted protocol, but the microvascular surgery literature recommends intraoperative anticoagulation with heparin. Here is reported a case of iliacus haematoma with subsequent femoral nerve palsy after the harvest of a microvascular iliac flap for mandibular reconstruction in a patient who had been treated with heparin. The association between femoral nerve palsy and anticoagulant therapy has been well described. It remains unclear as to why the iliacus muscle is particularly vulnerable to intramuscular haemorrhage. Femoral nerve neuropathy is also an uncommon but recognized complication after abdominopelvic surgery. Iliacus haematoma secondary to microvascular surgery has not been previously reported. This case illustrates the need to be aware of this type of complication and its clinical manifestations for patients under anticoagulant therapy in the perioperative period during microvascular reconstructions.

The anesthesia preoperative assessment: an opportunity for smoking cessation intervention.

Smoking is the single most cause of preventable disease and premature death in the United States. We discuss potential hazards that the anesthesiologist should be aware of when caring for patients who abuse tobacco. A review of recent preoperative smoking cessation initiatives is also provided in addition to recommendations on how anesthesiologists may use the preoperative visit as an opportunity to play a more active role in reducing the burden of tobacco-related disease.

Major vascular injuries during laparoscopic procedures.

BACKGROUND: Major vascular complications following laparoscopic procedures are rare, with only 20 cases reported in the literature. PATIENTS AND METHODS: The cases of 4 patients who sustained 5 vascular injuries during laparoscopic procedures between June 1991 and May 1994 are presented, and previously reported cases in the literature are reviewed. RESULTS: All injuries occurred during pelvic laparoscopy (2 diagnostic procedures, 1 tubal ligation, and 1 hernia repair). The vascular injury was recognized during laparoscopy in 3 patients. In only 1 patient was immediate vascular surgery consultation requested. The iliac artery was injured in 3 patients, the iliac vein in 1, and the inferior epigastric artery in 1. The mechanism of injury was by the trocar in 2 patients and by sharp dissection in 2 patients. Arterial repair was accomplished by polytetrafluoroethylene (PTFE) interposition, PTFE patch angioplasty, resection and primary anastomosis, and ligation in 1 patient each. The venous injury was repaired by lateral venorrhaphy. Three patients recovered without sequelae, and 1 patient had a stroke. A review of the literature revealed only 20 reported cases of major vascular injuries as a result of the pneumoperitoneum needle or trocar insertion. Characteristically, the terminal aorta, cava, iliac arteries, and veins were injured. Most injuries were treated by direct suture repair. With immediate recognition, recovery was the rule; however, 3 of the 8 patients with delayed recognition died. CONCLUSION: Laparoscopists must be aware of this rare, serious, and potentially lethal complication. Once recognized, immediate conversion to an open procedure and application of appropriate vascular surgical techniques are required to reestablish arterial and venous continuity and minimize morbidity and mortality.

Atraumatic vertebral artery dissection after cervical corpectomy: a traction injury?

STUDY DESIGN: Case report with review of the literature. OBJECTIVES: Presented is the first case of vertebral artery dissection secondary to intraoperative traction in cervical spine surgery. The pathogenesis and management of vertebral dissection in the immediate postoperative period are reviewed in detail. SUMMARY OF BACKGROUND DATA: Vertebral artery dissection is commonly associated with direct trauma, atraumatic or spontaneous. There are numerous reports of direct injury to the vertebral artery with cervical spine surgery, and it is a well-recognized risk. Cervical traction is also used routinely for improved placement of intervertebral devices/grafts. This is the first report of vertebral artery dissection occurring intraoperatively secondary to traction. The postoperative management is reviewed in detail. METHODS: Case study with extensive review of the literature. RESULTS: The patient underwent C6 corpectomy without intraoperative complications. Intraoperative wake-up test was normal. The patient remained intubated overnight for airway precautions. On postoperative day 1, the patient was lethargic and not following commands. Emergent CT of the brain and cervical spine revealed multiple posterior circulation infarcts with normal cervical spine and no hematoma. A stat angiogram revealed vertebral dissection. Medical management was initially attempted; however, infarcts continued, eventually requiring posterior fossa craniectomy/decompression and sacrificing the vertebral at the O-A junction. CONCLUSIONS: This is the first report of vertebral artery dissection occurring secondary to traction in cervical spine surgery. Surgeons must be aware that traction, even when performed appropriately, is not without risks. Anomalous vertebral arteries, osteophytes, and numerous other anatomic variants can lead to vertebral injury with traction.
