Surgical management of Ehlers-Danlos syndrome: first report of a pedigree in China.

OBJECTIVE: To describe a case of Ehlers-Danlos syndrome type IV and its pedigree in China. METHODS: Clinical materials of a case of Ehlers-Danlos syndrome type IV and a pedigree of 6 members within 4 generations were analyzed. Dilated internal jugular vein in the proband was removed by operation. The diagnosis, surgical treatment, and postoperative complications were retrospectively reviewed. RESULTS: Vessels of the proband in the pedigree were crisp and easily lacinated during the procedure of removing his internal jugular vein. Repeating postoperative hematomas were found though complete stanching was achieved during the operation. The patient was successfully recovered by promptly debridgement and needle sucking. The other 5 members of the pedigree all had the triads of Ehlers-Danlos syndrome. CONCLUSIONS: Though it was of extremely low morbidity rate, the high mortality rate and complication of Ehlers-Danlos syndrome deserve great attention during surgical management, especially in patients with Ehlers-Danlos syndrome type IV. Surgeons should be aware of the ponderance of its complications and combined diseases to avoid fatal intraoperative vascular lascination and incontrollable hemorrhage.

Primary repair of the cholecyst-enteric fistula in gallstone ileus.

Gallstone ileus is a rare cause of mechanical bowel obstruction. The attendant lack of awareness by the clinician will not only result in the diagnosis being made intraoperatively but will also affect the adequacy of the preoperative preparation of these ill patients. These patients are often elderly, septic and have significant concomitant medical illnesses. Recently two patients with gallstones ileus were managed with enterolithotomy and primary repair of the cholecyst-duodenal fistula at the University Hospital of the West Indies, Jamaica. Their clinical presentations and progress are described along with a review of the classical clinical course, radiological features, and operative choices available.

Intraoperative awakening of the patient during orthognathic surgery: a method to prevent the condylar sag.

PURPOSE: The intraoperative diagnosis, during orthognathic procedures, of an unfavorable condylar position is highly desirable. A simple technique that can reliably identify a malpositioned condyle intraoperatively has obvious advantages. The manual positioning of the condyle is easier, but it requires the utmost care and an experienced operator. Muscle tone is described as maintaining contact across the temporomandibular joint. The anesthetized and curarized patient has a condylar position posterior to that in the same patient when he is awake, with the same seating force applied. Under general anesthesia, the condyle may be inferior and might not feel stable until it moves posteriorly and has adequate compression of the retrodiscal tissues on the posterior wall. Relapse of the occlusion as a result of changes in the condylar position may occur immediately after the removal of the temporary intermaxillary fixation (IMF). The surgeon needs to understand the mechanism of condylar sag and the specific patterns of malocclusion that it may produce. This will enable him to make a diagnosis and to implement the appropriate corrective measures, providing the opportunity for immediate correction of condylar position, thereby obviating the need for a second operation or orthodontic compromise. MATERIALS AND METHODS: A study group (group A, 76 patients) and a control group (group B, 73 patients) were randomly formed from the dysgnathic patients scheduled for bimaxillary orthognathic surgery (Le Fort I osteotomy and bilateral sagittal split osteotomy). The free mandibular proximal segment was gently and manually positioned in the glenoid fossa. All the mandibles were fixed with bicortical screws. In group A, immediately after the fixation, IMFs were removed and the occlusions were checked with light digital pressure on the chin, then the patients were rapidly awakened (maintaining the intubation) in a state of conscious analgo-sedation and asked to open and close, and to laterally move the mandible. If clinical examination of the passive and active movements of the mandible was suitable, the anesthesia was reinforced and the operation was concluded. RESULTS: In 11 of the 76 patients of group A, malocclusion was noted, after the rigid fixation, with the method of digital pressure on the chin; the intraoperative awakening of the patients confirmed the clinical appearance and it provided further clinical signs to identify the offending condyle and to favor appropriate corrections. In 8 of the group A patients, malocclusions were not noted with manipulation of the mandible, but they were pointed out during the intraoperative awakening, and then they were appropriately corrected. In 2 of the group B patients, malocclusion was noted, after the rigid fixation, with the method of digital pressure on the chin, and it was immediately corrected. In 7 of the group B patients, malocclusion was not noted during the operation with the method of digital pressure on the chin, but it was noted at the end of the surgical procedure (12-24 hours after). CONCLUSION: Muscle tone, muscular activity, and proprioception appear to have important roles in the clinical evidence of a postoperative malocclusion during the intraoperative awakening; they can reliably implement the accuracy of the diagnosis of condylar sag, and they can favor its correction.

Post-tonsillectomy hemorrhage: an assessment of risk factors.

Hemorrhage is the most frequent complication of tonsillectomy and is responsible for the majority of post-tonsillectomy fatalities. The incidence of this hemorrhage has been reported to be as high as 20% [6]. Despite continued efforts to reduce this problem, it remains a persistent risk. The charts of 1138 patients who underwent tonsillectomy with or without adenoidectomy from 7-1-89 to 6-30-93 were reviewed. Post-tonsillectomy hemorrhage occurred in 36 patients (3%). Preoperative, intraoperative and postoperative risk factors were assessed. Postoperative bleeding occurred more often in older patients (69% over age 11 years). Seventy-five per cent of these patients were operated on for chronic tonsillitis as compared to 11% operated on for upper airway obstruction. The majority of these patients presented after postoperative day 1 (83%). Four patients required blood transfusions. Postoperative hemorrhage occurred in 14% of patients with elevated postoperative mean arterial pressures. Intraoperative blood loss that exceeded 50 cm3 was also a significant risk factor for post-tonsillectomy hemorrhage. It is concluded that older age, a history of chronic tonsillitis, excessive intraoperative blood loss and elevated postoperative mean arterial pressure are significant risk factors for post-tonsillectomy hemorrhage. An awareness of these risk factors can help identify patients with potential to bleed postoperatively.

Anaphylaxis due to latex allergy.

An anaphylactic reaction to latex is reported in two patients. One occurred intraoperatively with exposure to the surgeon's latex gloves and the other during vaginal contact with a latex condom. Radioallergosorbent test (RAST) and scratch test with latex material identified the allergen. With the increasing use of latex gloves and condoms, one should be aware of the possibility of a severe immediate hypersensitivity reaction to latex products. Latex allergy should be considered when evaluating intraoperative and idiopathic anaphylaxis.

Lateral condyle fractures in children: evaluation of classification and treatment.

OBJECTIVE: To compare intra-operative findings of fractures of the lateral condyle of the humerus in children with existing pre-operative radiographic classification. DESIGN: Prospective, consecutive. SETTING: Large urban hospital. PATIENTS: 25 consecutive displaced lateral condyle (humerus fractures) in 25 children diagnosed on biplanar radiographs. INTERVENTION: Open reduction and internal fixation through a lateral approach to the elbow. MAIN OUTCOME MEASUREMENTS: Anatomic variations of the lateral condyle of the distal humerus based upon intra-operative observations; comparison of findings with pre-operative radiographic classification. RESULTS: Three anatomic types were identified: 1) nine fractures exited on the medial side of the capitellum in the capitello-trochlear groove (36%), 2) eleven fractures exited beyond the capitello-trochlear groove through the trochlear epiphysis (44%), and 3) five fractures extended across the physis medially (20%). No fracture appeared to transverse the ossified portion of the capitellum (Milch Type I). The Milch anatomic classification was found to be inaccurate in 52% of the fractures. CONCLUSION: Intraoperative findings did not correlate with the presumed preoperative radiographic diagnosis in the majority of cases. A heightened awareness of the limitations of this traditional classification system is required for operative decision.

Perioperative pain management.

The clinical anesthesia, general surgery, and gynecology literature addressing the pathophysiology and management strategies for perioperative pain were reviewed. There are few prospective, randomized studies from which to draw meaningful conclusions. Nevertheless, a theoretical construct has been developed which may help the gynecologic surgeon optimizing pain management. The era of managed care and shorter hospital stays has focused physicians and, in particular, surgeons on elements of patient care that can be addressed and improved. Reducing or eliminating postoperative pain without excessive sedation promotes rapid mobilization and return to self-care. Strategies for pain management can be adopted that reduce postoperative ileus and other adverse reactions to analgesics.

Depth of anaesthesia monitoring: what's available, what's validated and what's next?

Depth of anaesthesia monitors might help to individualize anaesthesia by permitting accurate drug administration against the measured state of arousal of the patient. In addition, the avoidance of awareness or excessive anaesthetic depth might result in improved patient outcomes. Various depth of anaesthesia monitors based on processed analysis of the EEG or mid-latency auditory-evoked potentials are commercially available as surrogate measures of anaesthetic drug effect. However, not all of them are validated to the same extent.

Efficacy of therapeutic suggestions for improved postoperative recovery presented during general anesthesia.

There have been claims that the postoperative course of patients may be improved by presentation during general anesthesia of therapeutic suggestions which predict a rapid and comfortable postoperative recovery. This study evaluated the effectiveness of such therapeutic suggestions under double-blind and randomized conditions. A tape recording predicting a smooth recovery during a short postoperative stay without pain, nausea, or vomiting was played during anesthesia to about half the patients (N = 109), while the remaining, control patients were played a blank tape instead (N = 100). The patients were primarily undergoing operations on the fallopian tubes, total abdominal hysterectomy, vertical banding gastroplasty, cholecystectomy, and ovarian cystectomy or myomectomy. The anesthesia methods consisted of either isoflurane with 70% nitrous oxide in oxygen to produce end-tidal concentrations of 1.0, 1.3, or 1.5 MAC; or 70% nitrous oxide in oxygen combined with high or low doses of opioids. Assessments of the efficacy of the therapeutic suggestions in the recovery room and throughout the postoperative hospital stay included: the frequency of administration of analgesic and antiemetic drugs; opioid doses; the incidence of fever; nausea, retching, and vomiting; other gastrointestinal and urinary symptoms; ratings of pain; ratings of anxiety; global ratings of the patients' physical and psychological recoveries by the patients and their nurses; and length of postoperative hospital stay. There were no meaningful, significant differences in postoperative recovery of patients receiving therapeutic suggestions and controls. These negative results were not likely to be due to insensitivity of the assessments of recovery, as they showed meaningful interrelations among themselves and numerous differences in recovery following different types of surgery. Widespread utilization of therapeutic suggestions as a routine operating room procedure seems premature in the absence of adequate replication of previously published positive studies.

Awareness under anesthesia during electroconvulsive therapy treatment.

Awareness under general anesthesia is an infrequent phenomenon during which patients become cognizant of some or all events during surgery or any procedure conducted under anesthesia. Awareness experiences can frighten patients and impact their memories in ways that can leave emotional and psychological problems that, over time, may develop into posttraumatic stress disorder. Inadequate anesthesia has been implicated in the causation of awareness under anesthesia. We report first case of patient gaining awareness while under anesthesia undergoing electroconvulsive therapy treatment. The case reported here would suggest that clinicians administering electroconvulsive therapy should be alert to the possibility of awareness during anesthesia and take appropriate measures to maintain professional conduct and adjust anesthetic medication dose to avoid reoccurrence.

Retention of auditory information presented during anaesthesia. A study of children who received light general anaesthesia.

Surgical procedures that involve a local anaesthetic block are often accompanied by light general anaesthesia. It is possible that under these circumstances, the patients are more likely to register auditory events while apparently unconscious. Two groups of children were exposed to auditory stimuli during surgery; one group received a lighter level of anaesthesia than the other. Retention of the stimuli was tested using a cued recall technique, and the performance of the two experimental groups was compared with a control group which had not been exposed to the material but was tested in the same way. The light anaesthesia group retained more items than did the other two groups but this difference was significant (p less than 0.05) only when compared with the other experimental group. This is not very strong evidence of auditory registration, but a greater effect might be found with exposure to emotionally significant material. It is suggested that patients should be protected from unfortunate theatre conversation.

Awareness during anaesthesia for implantable cardioverter defibrillator implantation. Recall of defibrillation shocks.

Implantable cardioverter defibrillator implantation is performed under general anaesthesia. This report describes awareness or recall in two of 33 patients scheduled for implantation. After induction, anaesthesia was maintained using continuous infusions of propofol and atracurium and intermittent boluses of alfentanil. Propofol was given in the same arm as the implantation side. In these two patients propofol flowed out of the bleeding central venous access. To minimise the possibility of awareness, we advise that continuous infusions should be administered intravenously on the contralateral side to the implantation and that neuromuscular blocking agent be given by intermittent bolus injections.

Awareness during anaesthesia: what can be done to prevent it?

Awareness during general anaesthesia is a potentially traumatising risk of any general anaesthetic, which can have lasting effects on the patients who experience it. This article assesses the issues and causes of anaesthetic awareness, together with the current status of research being conducted into its prevention, and the effect of market forces and litigation.
