Traumatic anterior dislocation of the hip joint with posterior acetabular wall fracture.

The incidence of traumatic hip dislocation has increased in recent years as a result of high-energy trauma. Anterior hip dislocation forms less than 10-15% of all traumatic hip dislocations. Only a few case reports describe anterior dislocation along with acetabular fractures. The acetabular fracture involved the anterior wall or column in all such cases. We describe a rare case in which anterior superior dislocation of the hip was associated with a large fracture fragment of theposterior acetabular rim and adjacent wall.

Intraosseous neurilemmoma of L2 vertebra--a case report.

Intraosseous neurilemmoma (schwannoma) is a rare bone tumor with incidence less than 0.2% of all primary bone tumors. It is a benign neoplasm arising from the schwann cells of the nerve sheath. When they occur, they are usually found in the mandible. This paper reports an unusual occurrence of intraosseous neurilemmoma in L2 vertebral body. This patient presented with complaints of backache and progressively increasing weakness in both lower limbs. Roetengenograms showed an osteolytic lesion of L2 vertebra localized in the left half of the body and pedicle. Computed tomograph revealed a large soft tissue component of the tumor mass with thecal sac compression. A computed tomograph assisted needle biopsy revealed the tumor to be neurilemmoma. Subsequently, during decompression, it was possible to shell out tumor from surrounding tissues. Remaining tumor was curettedfrom bone and the cavity packed with autograft. The recovery was uneventful with incorporation of graft. The aim of this article is to highlight intraosseous neurilemmoma as a possible differential diagnosis in bony tumors. Intraosseous neurilemmoma of lumbar vertebrae is an extremely rare occurrence and till date only four cases are reported in English literature.

Rapid preparation of severe uncontrolled thyrotoxicosis due to Graves' disease with Iopanoic acid--a case report.

PURPOSE: To report the rapid preoperative preparation of a case of thyrotoxicosis due to Graves' disease resistant to medical treatment. CLINICAL FEATURES: A 14-yr-old boy presented with a history of progressive swelling in the neck. Signs and symptoms were compatible with hyperthyroidism. Thyroid function tests revealed: serum T4 296.5 nmol.L(-1), serum T3 6.06 nmol.L(-1) and serum thyroid-stimulating hormone < 0.15 mIU.L(-1). The diagnosis of thyrotoxicosis due to Graves' disease was made. Therapy was instituted with carbimazole 30 mg.day(-1) and propranolol 80 mg.day(-1), which were gradually increased to carbimazole 80 mg.day(-1) and propranolol 120 mg.day(-1), without response. Preparation was attempted by adding Iopanoic acid 500 mg four times a day and dexamethasone 0.5 mg four times a day in addition to the above drugs for five days. T3 levels declined to 1.8 nmol.L(-1), but the serum T4 remained elevated. Symptoms of hyperthyroidism persisted but with decreased intensity. As the patient could not be made euthyroid, surgery was planned to relieve the symptoms. Anesthesia was uneventful except for intraoperative and postoperative tachycardia, which was managed successfully with esmolol. CONCLUSION: In life threatening thyrotoxicosis refractory to medical treatment, Iopanoic acid may be used as an adjuvant to antithyroid drugs for rapid preparation of the patient prior to surgery.

Vein pretreatment with magnesium sulfate to prevent pain on injection of propofol is not justified.

PURPOSE: Propofol produces anesthesia with rapid recovery. However, it causes pain or discomfort on injection. A number of techniques have been tried for minimizing propofol-induced pain with variable results. We have compared the efficacy of magnesium and lidocaine for the prevention of propofol induced pain. METHODS: Three hundred ASA I and II adults undergoing elective surgery were randomly assigned into three groups of 100 each. Group I received magnesium sulfate 1 g, Group II received lidocaine 2% (40 mg) and Group III received normal saline, all in a volume of 2 mL and accompanied by venous occlusion for one minute. Induction with propofol 2.5 mg.kg(-1) was accomplished following the release of venous occlusion. Pain was assessed on a four-point scale: 0 = no pain, 1 = mild pain, 2 = moderate pain, and 3 = severe pain at the time of pretreatment and propofol injection. Results were analyzed by 'Z' test. A P value of < 0.05 was considered as significant. RESULTS: Pain during i.v. pretreatment with magnesium was 31% as compared to 2% for both the lidocaine and control groups (P < 0.05). Seventy-six percent of patients in the control group had pain during i.v. propofol as compared to 32% and 42% in the magnesium and the lidocaine groups respectively (P < 0.05). Lidocaine and magnesium pretreatment were equally effective in attenuating pain during the propofol injection (P > 0.05). CONCLUSIONS: Intravenous magnesium and lidocaine pretreatment are equally effective in attenuating propofol-induced pain. However, magnesium pretreatment itself causes pain. Therefore, there is no justification in the use of magnesium pretreatment for attenuating pain associated with i.v. propofol.

Concomitant double epiphyseal injuries of the tibia with vascular compromise: a case report.

A rare case of double epiphyseal injuries in the same tibia is reported. A 4-year-old child was struck by a vehicle and presented with the above fractures and vascular compromise to the extremity. Following localization of the vascular occlusion level by arteriography, popliteal vessel anastomosis was attempted. The vascular repair failed, resulting in disarticulation through the knee. Simultaneous displaced proximal and distal epiphyseal injury in the same tibia has not been previously reported in the literature. The most serious complication of injury to the proximal tibia is vascular compromise. A delay in recognition or intervention in such cases can be devastating.

Pretreatment with thiopental for prevention of pain associated with propofol injection.

UNLABELLED: Propofol causes pain on IV injection in 28%-90% of patients. A number of techniques have been tried to minimize propofol-induced pain, with variable results. We compared the efficacy of pretreatment with thiopental 0.25 mg/kg and 0.5 mg/kg and lidocaine 40 mg after venous occlusion for prevention of propofol-induced pain. One-hundred-twenty-four adult patients, ASA physical status I-II, undergoing elective surgery were randomly assigned into 4 groups of 31 each. Group I received normal saline, group II received lidocaine 2% (40 mg), and groups III and IV received thiopental 0.25 mg/kg and 0.5 mg/kg, respectively. All pretreatment drugs were made in 2 mL and were accompanied by manual venous occlusion for 1 min. Propofol was administered after release of venous occlusion. Pain was assessed with a four-point scale: 0 = no pain, 1 = mild pain, 2 = moderate pain, and 3 = severe pain at the time of propofol injection. Twenty-four patients (77%) complained of pain in the group pretreated with normal saline as compared with 12 (39%), 10 (32%), and 1 (3%) in the groups pretreated with lidocaine 40 mg, thiopental 0.25 mg/kg, and thiopental 0.5 mg/kg, respectively (P < 0.05). Thiopental 0.5 mg/kg was the most effective treatment. We therefore suggest routine pretreatment with thiopental 0.5 mg/kg along with venous occlusion for 1 min for prevention of pain associated with propofol injection. IMPLICATIONS: Pain associated with IV injection of propofol is seen in 28%-90% patients. Pretreatment with thiopental 0.25 mg/kg and 0.5 mg/kg after manual venous occlusion for 1 min effectively attenuated pain associated with propofol injection. Thiopental 0.5 mg/kg was the most effective in prevention of propofol pain and can be used routinely.

Pain during injection of propofol: the effect of prior administration of butorphanol.

Propofol causes pain or discomfort on injection in 28%-90% of patients. A number of techniques have been tried for minimizing propofol-induced pain with variable results. We compared the efficacy of butorphanol and lidocaine for prevention of propofol-induced pain. One-hundred-fifty ASA I-II adults, undergoing elective surgery were randomly assigned into 3 groups of 50 each. Group I (NS) received normal saline, Group II (L) received lidocaine 2% (40 mg), and Group III (B) received butorphanol 2 mg. All patients received pretreatment solutions made in 2 mL with normal saline administered over 5 s. One min after pretreatment patients received one-fourth of the total calculated dose of propofol (2.5 mg/kg) over 5 s. Assessment of pain with IV propofol was done by using a four-point scale: 0 = no pain, 1 = mild pain, 2 = moderate pain and 3 = severe pain at the time of propofol injection. In the control Group 39 (78%) patients had pain during propofol injection as compared to 21 (42%) and 10 (20%) in the lidocaine and butorphanol groups, respectively (P < 0.05). Butorphanol was the most effective. We therefore suggest the IV pretreatment with butorphanol 2 mg for attenuation of pain associated with propofol injection.

The effect of epidural bupivacaine on induction and maintenance doses of propofol (evaluated by bispectral index) and maintenance doses of fentanyl and vecuronium.

The growing interest in combining local and general anesthesia has led to studies investigating possible interactions between general anesthesia and local anesthetics administered via spinal, epidural, IV, or IM routes. However, no study has evaluated the effect of local anesthetics on all three components of balanced anesthesia, i.e., hypnosis, analgesia, and muscle relaxation. In this prospective, randomized, double-blind study, we investigated the effect of epidural bupivacaine on the dose requirement of propofol (as evaluated by using the bispectral index [BIS]), fentanyl, and vecuronium for general anesthesia. This study consisted of 30 adults, ASA physical status I and II, undergoing Whipple's pancreaticoduodenectomy for periampullary carcinoma lasting >4 h. An epidural catheter was placed between T9-10. Depending on the group allocation, 10 mL of the study drug was administered as a bolus followed by an infusion at 6 mL/h via the epidural catheter. Patients were divided into 2 groups of 15 each. Patients in the control group received epidural normal saline whereas those in the bupivacaine group received epidural bupivacaine 0.1%. Induction of anesthesia was performed with IV fentanyl 2 mug/kg and propofol titrated to achieve BIS between 40-50. Endotracheal intubation was facilitated by the IV administration of vecuronium 0.1 mg/kg and patient's lungs were ventilated with 66% nitrous oxide in oxygen. After intubation, infusion of propofol 1% was titrated to maintain BIS between 40-50. Inadequate analgesia was defined as an increase in systolic blood pressure and/or heart rate by >20% of baseline values in response to surgical stimulus and was treated with bolus fentanyl 0.5 mug/kg. Neuromuscular monitoring was used to assess the need for additional doses of vecuronium. Data were analyzed by using the Student's t-test and P </= 0.05 was considered significant. The requirement of propofol for induction and maintenance of anesthesia in the bupivacaine group was 1.3 +/- 0.3 mg/kg and 2.4 +/- 0.9 mg . kg(-1) . h(-1), respectively, compared with 2.4 +/- 0.6 mg/kg and 4.4 +/- 1.6 mg . kg(-1) . h(-1) observed in the control group (P < 0.05). Significant reduction was also observed in the requirement of vecuronium and fentanyl during maintenance in the bupivacaine group (P < 0.05). We conclude that epidural bupivacaine given before induction of anesthesia reduces the requirement of propofol, fentanyl, and vecuronium during general anesthesia.

Intravenous lidocaine suppresses fentanyl-induced coughing: a double-blind, prospective, randomized placebo-controlled study.

IV lidocaine is effective in suppressing the cough reflex of tracheal intubation, extubation, bronchography, bronchoscopy, and laryngoscopy. We investigated this effect of lidocaine on fentanyl-induced cough in 502 patients of ASA physical status I and II scheduled for elective surgery. The patients were assigned to 2 equal groups to receive either lidocaine 1.5 mg/kg or placebo (0.9% saline) over 5 s 1 min before the administration of fentanyl 3 mug/kg in a randomized and double-blind fashion. Coughs were classified as coughing and graded as mild (1-2), moderate (3-4), or severe (5 or more). The results of the study suggest that IV lidocaine 1.5 mg/kg, when administered 1 min before fentanyl, is significantly effective in suppressing fentanyl-induced cough compared to placebo (0.9% saline) (218 versus 165 patients) (P < 0.002) but without affecting the severity of cough (P > 0.05).

Floating injuries: a review of the literature and proposal for a universal classification.

It is tempting to describe any structure or body part which is not in continuity with its adjacent structures as 'floating'. The indiscriminate use of this word has led to description of complex injury patterns, surgeries, congenital anomalies, functional deformities or even normal anatomical structures by a single vague term 'floating'. The article stresses the importance of proper description of an injury pattern, after enlisting some of the 'floating' entities described in the literature. When the term 'floating' is used to describe an injury in a limb, we suggest use of the proposed universal classification system to prevent ambiguity, help in prognosticating and scientific comparison of results in such injuries.

Salbutamol, beclomethasone or sodium chromoglycate suppress coughing induced by iv fentanyl.

PURPOSE: Fentanyl, a synthetic opioid, is a popular choice amongst anesthesiologists in the operating room. Preinduction iv fentanyl bolus is associated with coughing in 28-45% of patients. Coughing due to fentanyl is not always benign and at times may be explosive requiring immediate intervention. We have studied the role of aerosol inhalation of salbutamol, beclomethasone and sodium chromoglycate in preventing fentanyl induced coughing and have compared their efficacy. METHODS: Two hundred patients aged 18-60 yr, undergoing elective laparoscopic cholecystectomy were randomized into four groups of 50 each. Group I served as control, while Groups II, III and IV received an aerosol inhalation of salbutamol, beclomethasone or sodium chromoglycate 15 min prior to entering the operating room. Following iv fentanyl (2 micro g x kg(-1)) the incidence of cough was recorded and graded as mild (1-2), moderate (3-5) and severe (> 5) depending on the number of coughs observed. Results were analyzed using 'z' and Fischer's Exact test. A P value of < or = 0.05 was considered significant. RESULTS: The incidence of cough was 28% in the control group, 6%, 0% and 4% in the salbutamol, beclomethasone and sodium chromoglycate groups respectively. Occurrence of cough was significantly low (P < or = 0.05) in the treatment groups, however the difference amongst the groups was not significant (P >/= 0.05). CONCLUSION: The use of salbutamol, beclomethasone or sodium chromoglycate aerosol 15 min prior to iv fentanyl administration minimizes fentanyl-induced coughing.

Primary rhabdoid tumor of the gallbladder: report of a case.

A 46-year-old man was operated on for cholelithiasis with chronic cholecystitis. On gross inspection of the resected gallbladder, a slight thickening in the body wall, in an area measuring about 1 x 0.5 cm, was noted. On light microscopic and immunohistochemical examinations, the lesion was diagnosed to be a rhabdoid tumor. After a thorough review of the literature we failed to find any reference to such a lesion in the gallbladder. This is the first known case report of a rhabdoid tumor of the gallbladder.

Oxygen in air (FiO2 0.4) improves gas exchange in young healthy patients during general anesthesia.

PURPOSE: One hundred percent O(2) is used routinely for preoxygenation and induction of anesthesia. The higher the O(2) concentration the faster is the development of atelectasis, an important cause of impaired pulmonary gas exchange during general anesthesia (GA). We evaluated the effect of ventilation with 0.4 FiO(2) in air, 0.4 FiO(2) in N(2)O and 100% O(2) following intubation on the development of impaired gas exchange. METHODS: Twenty-seven patients aged 18-40 yr, undergoing elective laparoscopic cholecystectomy were administered 100% O(2) for preoxygenation (three minutes) and ventilation by mask (two minutes). Following intubation these patients were randomly divided into three groups of nine each and ventilated either with 0.4 FiO(2) in air, 0.4 FiO(2) in N(2)O or 100% O(2). Arterial blood gases were obtained before preoxygenation and 30 min following intubation for PaO(2) analysis. Subsequently PaO(2)/FiO(2) ratios were calculated. Results were analyzed with Student's t test and one-way ANOVA. P value of < or = 0.05 was considered significant. RESULTS: Ventilation of the lungs with O(2) in air (FiO(2) 0.4) significantly improved the PaO(2)/FiO(2) ratio from baseline, while 0.4 FiO(2) in N(2)O or 100% O(2) worsened the ratio (558 +/- 47 vs 472 +/- 28, 365 +/- 34 vs 472 +/- 22 and 351 +/- 23 vs 477 +/- 28 respectively; P < 0.05). CONCLUSION: Ventilation of lungs with O(2) in air (FiO(2) 0.4) improves gas exchange in young healthy patients during GA.
