[The administration of continuous epidural block under prone position with fluoroscopic guidance].

Continuous epidural block is often used for the treatment of pain. But there have been unsuccessful cases by the routine blind method. We devised a modified method of administering continuous epidural block under prone position with fluoroscopic guidance. The purpose of this study was to evaluate the utility of our modified method. There were 18 cases with pain of lumbar region and 28 cases of thoracocervical region in whom it was not possible to obtain successful control of pain by routine method. By our method, 14 cases (77.8%) with pain of lumbar region and 24 cases (85.7%) of thoracocervical region had effective epidural catheterization. There was no complication. As unsuccessful cases were accompanied with epidural adhesion or psychological disease, they might have no indication for continuous epidural block.

Modified prone position for cranial remodeling procedures in children with craniofacial dysmorphism: a technical note.

A new head position for use during operation on young children with cranial deformities is described. The position allows exposure of the entire calvarium from the supraorbital ridges to the posterior rim of the foramen magnum. It is a modification of the conventional prone position involving hyperextension of the neck. The authors have safely used this position to perform one-stage radical cranial remodeling procedures that previously required two stages. The advantages of this position and the methods for achieving it are discussed.

Repeat ketamine anaesthesia of a child for radiotherapy in the prone position.

Sixteen ketamine anaesthetics over an eight-week period for a course of postoperative radiotherapy following removal of a medulloblastoma in an 18-month-old child are described. On each occasion the child was in the prone position with a tight fitting shell covering the head, trunk and arms. The problems of repeated anaesthetics, isolation of the child in one room from the anaesthetist in another, and psychological upset to the mother and child are discussed. Ketamine was chosen because with this agent the patient usually maintains a clear airway, even in unusual postures. It was used successfully by both the intramuscular and rectal routes, thus avoiding repeated venepuncture and intubation. Post-anaesthetic nausea was a problem, but tolerance to ketamine and psychological emergence phenomena did not occur.

[Acute tension pneumocephalus as a complication of surgical procedures of the posterior cranial fossa in prone position].

The authors describe a case of acute tension pneumocephalus (TP) developing as a complication of an operation in the posterior cranial fossa, in a boy aged 3 years with a large cystic tumour of the vermis, operated on in prone position with flexed head. The authors discuss the circumstances leading to development of tension pneumocephalus.

Cardio-respiratory changes with increased intra-bladder pressure in prone position during anesthesia.

Twenty non-obese patients, 13-29 years of age, operated on for scoliosis were examined for cardio-respiratory changes that occur during positioning on bolsters, and the effect on the cardio-respiratory system of raised intra-abdominal pressure was evaluated. Hemodynamic and respiratory responses were measured when the position was changed from supine to prone and back to supine during anesthesia. We measured the intra-bladder pressure using a transurethral catheter (IBP) as an index of the intra-abdominal pressure. When the position was changed from supine to prone, the cardiac index (CI) decreased by 10-30% and the systemic vascular resistance index increased by 8-14%. IBP rose significantly ( P < 0.001), but it remained below 5 mmHg. These changes continued to be mild until the patient was returned to the supine position. Pa(O)(2), A-aD(O)(2)and Qs/Qt remained unchanged. CI decreased significantly ( P < 0.001) when IBP was increased to 10 mmHg by abdominal compression, but was not affected when IBP was increased to only 5 mmHg. It was concluded that mild abdominal compression in the prone position during anesthesia has little effect on the cardio-respiratory system in lean young subjects.

The prone position for transurethral resection of anterior bladder-wall tumours.

Transurethral resection of tumours of the anterior bladder wall may be technically difficult. The resectoscope must be held with an awkward upside-down grip and the surgeon assume an uncomfortable position, particularly as the bladder fills and causes the tumour to drift away from the surgeon. There is a risk of intraperitoneal perforation as the surgeon cuts more deeply to resect the tumour. When the patient is in the prone position the tumour is more accessible. This allows it to be resected more easily, more thoroughly and more comfortably. The technique may be used in men as well as in women.

[Computerized tomography in ventral and lateral prone position in the differential diagnosis of subdural hematoma and cortical atrophy].

The differential diagnosis between brain atrophy versus subdural effusion in children has shown some difficulties in a few cases, mainly when the frontal subarachnoid space is very large on computed tomography. We think that a simple procedure, that is, CT scans in the lateral and prone position following the standard examination, may be worth to clarify those cases of doubtful diagnosis.

Value of prone positioning in the ultrasonographic diagnosis of gallstones: prospective study.

To determine prospectively the value of prone/postprone positioning in the sonographic detection of gallstones, 682 patients were scanned in the recumbent, erect, and prone or postprone positions. The gallbladder was evaluated for an intraluminal hyperechoic focus, shadowing, and gravitational dependence and was identified in 679 patients. Among these, 28% had cholelithiasis. In five cases, prone positioning alone revealed gallstones. In 11 of 140 cases, gravitational dependence was only seen with prone scanning. The gallbladder was seen more frequently when the patients were prone than erect. Prone or postprone scanning is a useful supplement to the gallbladder examination, allowing increased demonstration of gravitational dependence and increased stone detection.

[Lesions of the pineal and tentorial region. Occipito-parietal approach in three-quarter prone position with infrasagittal craniotomy].

Surgical treatment of pineal-tentorial region lesions remains a challenge. The difficulty in approaching the pineal region can be verified with the number of operative plans that have been proposed to reach this area: transcallosal, occipital transtentorial, infratentorial supracerebellar approaches and sitting, prone or Concorde positions. This emphasizes the surgeon's dissatisfaction with the surgical techniques described. Recently, a three-quarter prone position with the bone flap placed under the midline has been described (1, 3, 8). We have decided to test this approach that we have slightly modified and we report our results on 13 cases: 2 arachnoid cysts, 3 vascular malformations and 8 tumors (3 brainstem gliomas, 2 dysgerminomas, 1 quadrigeminal plate metastasis and 1 meningioma plus 1 metastasis of the falx). Keeping the table in a horizontal plane, risks of air embolus are eliminated. Using the natural effect of gravity, traction on the occipital lobe is no more necessary and hemianopsia no more occurs. We recommand the parieto-occipital route which is the shortest way to reach epiphysis and falco-tentorial notch. We confirm the results of american colleagues (1, 3, 8, 15) and we advise to use this approach which seems to us the best way to treat pineal-tentorial lesions.
